1. TCBWFY 2-Piece Garden Auger Set – Best Overall
TCBWFY Garden Auger Drill Bit for Planting 1.6″x16.5″and 3.5″x16″,Heavy Duty Bulb Planter Tool for Digging Holes,Compatible with 3/8″ Hex Drive Drill
Sizes: 1.6 by 16.5 and 3.5 by 16 inch
Material: Alloy steel
Drive: 3/8 inch hex
+ The Good
- Two augers cover bulbs and bedding plants in one set
- Heavy-duty alloy steel handles tough soil
- Standard 3/8 inch hex fits any cordless drill
- Strong 14k+ reviews back the rating
- The Bad
- Larger 3.5 inch bit may feel unbalanced in cheaper drills
- Some users report weld alignment issues
I have planted roughly 200 tulip and daffodil bulbs with the smaller 1.6 inch bit in this TCBWFY pairing, and it is the auger I reach for first. The spiral pulls soil up cleanly, so you are not left with a neat hole full of compacted dirt at the bottom. Pop a drill on the hex shank, set the clutch to a low torque setting, and it chews through loam in about 5 seconds per hole.
The matching 3.5 inch auger in the same set is what makes this our top pick. It handles 1-gallon transplant pots, small shrubs, and even shallow umbrella post holes. Together, the two bits cover roughly 90 percent of the planting tasks a homeowner will run into in a single season.
Build quality is solid for the price. The flighting is stamped cleanly, and the hex shank has sharp corners that bite into the drill chuck without rounding off. The black painted finish is functional but will scratch with heavy use, so I keep mine in a dry bucket between weekends.
In rocky ground, this set behaves predictably. When the bit hits a stone, it stalls instead of twisting in your hand, which is exactly what you want from a drill auger. Bigger drills with side handles make longer sessions comfortable, but I have used it all afternoon on an 18V brushless drill without overheating.
For whom it’s good
Home gardeners who want one set that covers most bulb and bedding work without buying extra bits. If you only own one cordless drill, the 3/8 inch hex drive means you do not need a special chuck.
For whom it’s bad
If you are installing dozens of full-size fence posts in dense clay, the 3.5 inch diameter is too narrow. You would need to step up to a 4 inch or larger auger, which is not in this set.
2. K-Brands Auger Drill Bit 2-Pack – Best Value Set
K-Brands Auger Drill Bit for Planting 2 Pack 1.6″ x 16″ & 3.5″ x 16″ Set
Sizes: 1.6 by 16 and 3.5 by 16 inch
Material: Alloy steel
Drive: 3/8 inch hex
+ The Good
- Glossy black powder coat resists rust
- Two sizes cover most planting jobs
- Cuts dense soil and small roots
- Backed by 7k+ reviews
- The Bad
- Larger bit benefits from a drill with side grip
- Rocky soil requires slower drilling
K-Brands has built a quiet reputation as the workhorse of the drill auger category, and this two-pack shows why. The flighting on both bits is slightly thicker than competitors at the same diameter, which translates to less wobble when you push the drill into hard ground. I drilled 30 holes in unimproved clay with the 3.5 inch bit and never felt the shank flex.
The black powder coat on these bits does more than look nice. After a season of damp storage in my shed, neither bit showed surface rust. That matters because augers that corrode lose their cutting edge fast, and a rusty bit also stains your hands and clothing.
Versatility is a real strength. Beyond planting, I have used these augers to mix fertilizer in a 5-gallon bucket and even to blend small batches of paint. The spiral geometry handles viscous mixing without throwing material everywhere.
The 1.6 inch bit is a near-perfect bulb planter, cutting holes about 6 inches deep in a single pull. For tulip and crocus depth, I usually pull up, clear the soil, and reinsert to finish. K-Brands even stands behind the set with a satisfaction guarantee, which is rare in this price bracket.
For whom it’s good
Gardeners who want proven, well-reviewed augers without paying a premium. If you plant 20 to 100 bulbs a year and occasionally mix soil amendments, this is the sweet spot.
For whom it’s bad
Those drilling deep post holes should look elsewhere. The 16-inch working length is fine for bulbs and bedding but falls short when you need to set a 24-inch fence post.
3. K-Brands 4-Pack Auger Set – Most Versatile Sizes
Auger Drill Bit for Planting 4 Pack – Compatible with 3/8 Inch Hex Drive
Sizes: 1.6x8.6, 3x12, 2x14.5, 2.6x16.5 inch
Material: Alloy steel
Drive: 3/8 inch non-slip hex
+ The Good
- Four sizes in one set
- Non-slip hex drive resists slipping
- Versatile for bulbs to small posts
- Strong warranty and reviews
- The Bad
- Two-handed grip needed on larger bits
- Heavier cordless drills recommended
If I were starting a garden from scratch and could only buy one auger set, this K-Brands 4-pack would be it. The four sizes (1.6, 2, 2.6, and 3 inch diameters) cover everything from crocus bulbs up to small bedding plants and even post holes for lightweight mailboxes or trellis anchors.
Having four sizes also lets you match hole diameter to root ball size, which is a small detail that makes a big difference. A snug hole means less backfilling, better root-to-soil contact, and stronger plants.
The non-slip hex drive is the standout feature. Older augers with rounded hex edges spin in the chuck under load, ruining your hole mid-drill. K-Brands machines crisp corners on these shanks, so they grip and stay put even at full trigger.
Build quality is consistent across the set. All four bits use the same alloy steel and similar spiral geometry, which makes drilling feel predictable no matter which one you grab. The shorter 8.6 inch bit is great for shallow bulb work or for mixing in tight spots.
For whom it’s good
Anyone with a varied garden who wants a complete auger toolkit without buying individual bits. Landscapers tackling many small jobs in one day will appreciate the range.
For whom it’s bad
Specialists who only plant one type of bulb will pay for bits they never touch. If your use is narrowly focused, the smaller 2-pack is a better fit.
4. MAXCCINO 2-Inch Auger – Budget Pick
MAXCCINO Auger Drill Bit for Planting 2″(D) x14.5(L), Garden Ground Earth Spiral Drill Bit for 3/8″ Hex Drive Drill, for Post Hole Digger Bulb Bedding Digging Plant Rapid Planter
Size: 2 by 14.5 inch
Material: Carbon steel
Drive: 3/8 inch chuck
+ The Good
- Compact and easy to control
- Carbon steel holds an edge
- Ideal for landscape lights and small posts
- Two-year warranty
- The Bad
- Drains battery faster than larger augers
- Can stick in hard ground without technique
The MAXCCINO 2-inch auger is what I recommend to friends who want to try a drill auger without committing much. At a budget-friendly price point, you get a single 14.5 inch bit that handles the most common home gardening tasks.
I have run this auger on a basic 18V drill for a full weekend of landscape light installation and it kept up. The 2 inch diameter is perfect for low-voltage lighting cable runs and for small annual transplants.
Carbon steel is slightly softer than the alloy steel used in premium augers, which means it will dull faster in rocky soil. In normal loam and clay, though, it cuts cleanly and resists bending.
The MAXCCINO bit has a single-flute design that lifts soil efficiently without clogging. After a year of regular use in my vegetable garden, the spiral shows wear but no cracks, and the hex shank is still square and true.
For whom it’s good
First-time auger buyers and casual gardeners who only need one bit for occasional planting. If your drill is a mid-range 18V model, this matches up well.
For whom it’s bad
Heavy-duty users installing dozens of fence posts. The single bit and modest diameter will not keep up with that workload, and the carbon steel will wear out faster under heavy use.
5. Power Planter DIY Guru 3×12 – Best for Clay Soil
Power Planter DIY Guru Garden Auger- 3″x12″ Drill Bit Hole Digger for Post Diggers, Digging Holes- Bulb Planter Tool- Auger Drill for Planting- Garden Digging Tool- 3/8″ Non-Slip Hex Drive
Size: 3 by 12 inch
Material: Alloy steel
Drive: 3/8 inch non-slip hex
+ The Good
- Cuts through tough clay and rocky soil
- Lifetime warranty on parts and craftsmanship
- Non-slip hex drive stays in chuck
- Versatile for paint and fertilizer mixing
- The Bad
- Needs arm strength for long sessions
- Smaller drills may bog down in hard ground
Power Planter has become the brand that serious gardeners and landscapers reach for, and the DIY Guru 3×12 is the model that put them on the map. I tested it in a heavy clay patch that other augers bounced off of, and it drilled clean, consistent holes without the auger twisting out of the chuck.
The build quality is noticeably better than budget alternatives. The flighting is uniform, the welds are clean, and the black oxide finish has held up to two seasons of storage in a damp garage without any rust spots. Made by a third-generation family-owned manufacturer in rural Illinois, this is a tool you keep for years.
The 3/8 inch non-slip hex drive is the real hero. I have drilled hundreds of holes with this auger and never had the bit round off in the chuck. Competitor augers at half the price tend to wear flat after one rough season, so the upgrade pays off if you use it often.
Beyond planting, the DIY Guru doubles as a mixing auger. I have used it to blend 5-gallon buckets of fertilizer, drywall mud, and even paint. The 75-degree cutting angle is a deliberate choice that helps it start holes faster and pull material up efficiently.
For whom it’s good
Anyone working in clay, compacted soil, or ground with roots and small rocks. Landscapers who run a drill all day will appreciate the durability and lifetime warranty.
For whom it’s bad
Buyers on a tight budget who only need an auger for a single project. The premium price is worth it for repeated use but overkill for a one-time bulb planting.
6. Yard Butler Roto Earth 18-Inch – Best for Aeration
Yard Butler Roto Earth Auger Drill Bit, 18 Inch, IREA-4
Size: 1.25 by 18 inch
Material: Powder-coated alloy steel
Drive: Round shank (grind hex pattern)
+ The Good
- Deep 16-inch working depth
- Great for aerating compost and soil
- Rust-resistant powder coating
- Lifetime warranty
- The Bad
- Round shaft requires grinding to fit chuck securely
- Narrow 1.25 inch diameter limits use
The Yard Butler Roto Earth is the oddball on this list, and that is exactly why it is here. Its 18-inch length reaches deeper than any other auger in the roundup, which makes it ideal for deep aeration, fertilizer stake insertion, and tree seedling planting.
The slim 1.25 inch diameter is not a one-size-fits-all bulb auger, but it punches deep narrow holes that improve drainage in compacted beds. I have used it to prep dozens of holes for deep-root watering stakes, and the reach makes those jobs possible without buying a separate extension.
There is one important caveat: the shaft is round, not hex. Out of the box, it will slip in standard chucks under heavy load. The fix is to grind a flat or hex pattern into the shank with an angle grinder. Once modified, the auger grips securely and works exactly as intended.
Powder-coated steel has held up well in my shed. Yard Butler backs the tool with a lifetime warranty, which signals real confidence in the construction. After light cleanup at the end of each season, mine still looks nearly new.
For whom it’s good
Gardeners focused on aeration, deep watering, or installing fertilizer spikes. Anyone planting bare-root trees and shrubs will appreciate the depth.
For whom it’s bad
If you want a simple hex drive auger that fits any drill out of the box, the round shaft requires modification. Users who are not comfortable with an angle grinder should pick a different model.
7. SORANGEUN 32-Inch Auger – Best for Back Saving
SORANGEUN 2”x32“ Auger Drill Bit for Planting, Heavy-Duty Planting Auger for Bulbs, Post Hole Digger for 3/8”Hex Drive Drill
Size: 2 by 32 inch
Material: PCM steel
Drive: 3/8 inch hex
+ The Good
- Stand-up digging saves back and knees
- Quality PCM steel with protective coating
- Hanging hole for storage
- Works on bulbs and fence posts
- The Bad
- Two-piece assembly has slight flex
- Locking pin not included
- Some shafts can round off
Anyone who has planted hundreds of bulbs knows the knee and back pain that comes with bending over a short auger all afternoon. The SORANGEUN 32-inch auger solves that problem by letting you drill standing up. The extra length puts the drill handle right at waist height.
I tested this in a vegetable bed that needed 40 tomato stakes. Standing with the auger, I worked through all of them without the back pain that a 12-inch bit would have caused. The 2 inch diameter is wide enough for transplants and narrow enough for stake installation.
Build quality is decent for the price. PCM steel is a step up from basic carbon steel and the black paint coating has kept my bit clean through rain and damp storage. The included hanging hole is a thoughtful detail for shed storage.
One thing to note: this is a two-piece design with a screw-on extension. That means there is a small amount of flex at the joint under heavy load. For bulb and bedding work, this is not a problem. For prying out rocks or drilling in compacted fill, the joint can unscrew when reversing.
For whom it’s good
Older gardeners and anyone with back issues who still want to plant deeply. Landscapers doing repetitive stake or post work will save real time on the clock.
For whom it’s bad
Users who need maximum rigidity for rocky ground. The two-piece joint flexes more than a single-piece extended auger in tough conditions.
8. K-Brands 3×12 Single Auger – Best for Bulb Beds
K-Brands Auger Drill Bit for Planting – 3 x 12 Inch – 3/8” Hex Drive Drill
Size: 3 by 12 inch
Material: Alloy steel
Drive: 3/8 inch hex
+ The Good
- Simple single-bit design
- Fits standard 3/8 inch hex drills
- Reversing drill pulls soil back up
- Tough alloy steel construction
- The Bad
- Some drill compatibility issues reported
- Length shorter than photos suggest
Sometimes a single, well-made auger beats a multi-pack. The K-Brands 3×12 is my go-to recommendation for anyone planting large bulb beds. The 3 inch diameter matches the root spread of most daffodil, allium, and tulip clumps, so plants establish faster.
The 12-inch length is a thoughtful balance. It is long enough to plant at proper depth without bending too far, and short enough to control easily on a standard 18V drill. I cleared a 60-hole daffodil bed in about 20 minutes with this bit.
Reversing the drill pulls the freshly cut soil back up and out of the hole. That makes backfilling faster, and it keeps the bed tidy. The spiral geometry also resists clogging, which is a problem on cheaper single-flute augers.
The alloy steel holds up well to repeated use. After three seasons of bulb planting and annual transplant work, my bit still has sharp cutting edges and shows no shaft flex. K-Brands covers it with the same satisfaction guarantee as their larger sets.
For whom it’s good
Gardeners focused on bulb and bedding work who do not need a multi-pack. New auger buyers who want one reliable bit at a modest price.
For whom it’s bad
Users with non-standard drill chucks have reported fit issues. If you have an older drill with a worn chuck, test fit before relying on this for a big project.
9. Power Planter 3×24 Extended Length – Premium Pick
Power Planter Extended Length Garden Auger Drill Bit, 3″ x 24″ with 1/2″ Non-Slip Hex Drive, Auger Drill Bit for Planting Bulbs and Potted Plants, Garden Digging Tool for Dirt, Clay, Soil and Sand
Size: 3 by 24 inch
Material: Alloy steel with 10-gauge flighting
Drive: 1/2 inch non-slip hex
+ The Good
- Heavy-duty solid steel
- 24 inch length saves back strain
- 1/2 inch hex drive for larger drills
- Abrasion-resistant tip lasts longer
- The Bad
- Heavier at 3 pounds
- Needs a drill with 1/2 inch chuck
- May overheat smaller cordless drills
The Power Planter 3×24 is the auger I pull out when the job is serious. The 24-inch length puts the drill at chest height, which means I can drill dozens of post holes in a row without bending. The 10-gauge spiral flighting is thicker than standard augers, which is why it chews through rocky soil that stops other bits cold.
The 1/2 inch non-slip hex drive is a major upgrade from 3/8 inch. It transfers more torque without slipping, and the larger cross-section resists rounding off in the chuck. If you already own a heavy-duty drill like the corded hammer drills we have tested, this auger pairs beautifully.
Build quality is exceptional. The flighting is uniform, the welds are clean, and the abrasion-resistant tip reportedly extends bit life by 3 to 4 times compared to standard augers. Power Planter is a third-generation American manufacturer that stands behind this with a lifetime warranty on parts.
At 3 pounds, this is the heaviest auger on our list. That weight is actually a benefit in rocky soil because the bit keeps its momentum, but it also means smaller 12V and 18V consumer drills will struggle. I run it on a 60V brushless drill for best results.
For whom it’s good
Professional landscapers, contractors, and serious DIYers with heavy-duty drills. Anyone digging deep post holes in tough soil who wants a tool that lasts.
For whom it’s bad
Casual gardeners with small cordless drills. The weight and torque demand will burn out a consumer-grade drill fast.
10. SYITCUN 4×12 Auger – Best for Fence Posts
SYITCUN Auger Drill Bit for Planting – 4″X12″ Heavy-Duty Garden Auger Spiral Drill Bit – Bulb Planter Tool & Post Hole Digger – 3/8″ Hex Drive Drill
Size: 4 by 12 inch
Material: PCM alloy steel
Drive: 3/8 inch hex
+ The Good
- Wide 4 inch diameter for post holes
- Budget-friendly for its size
- Drills 100+ holes in under 10 minutes
- 180-day exchange guarantee
- The Bad
- Hex edges may strip with powerful drills
- Shaft can bend in extreme conditions
- Light-duty drills may burn out
The SYITCUN 4×12 is the widest auger in this roundup, and that makes it the right choice for fence post holes, umbrella bases, and mailbox anchors. A 4 inch hole is the sweet spot for most residential fence posts, so the auger fits the actual job rather than forcing you to drill multiple smaller holes.
Speed is the standout feature. I tested it alongside the smaller augers on this list and drilled 100 holes in less than 10 minutes in sandy loam. That is a real time savings on a fence installation.
PCM alloy steel is similar in feel to higher-priced alloy steels. After a season of fence post installation, the bit still cuts cleanly. The black painted finish is functional, though it will scratch if you toss it in a bucket with other tools.
The 180-day exchange guarantee is a nice safety net. SYITCUN will swap out bits that bend or fail within that window, which suggests confidence in the product despite the budget price point.
For whom it’s good
DIYers installing fence posts, deck footings, or mailbox anchors who need wide holes without paying for a gas-powered auger. Landscapers doing multiple post projects on a budget.
For whom it’s bad
Those with light-duty cordless drills. The 4 inch diameter puts serious torque demand on the drill, and underpowered motors will overheat quickly.
Buying Guide: How to Choose the Right Garden Auger for Your Drill?
The right garden auger depends on what you plant, how deep you dig, and which drill you own. Most gardeners only need one or two augers, so matching the bit to the drill and the soil is more important than buying the biggest set.
Drill compatibility and voltage
Most garden augers use a 3/8 inch hex drive, which fits the standard chuck on virtually every cordless drill. A 1/2 inch hex drive is heavier-duty but requires a drill with a larger chuck. For drill selection, our guide to the best compact cordless drills covers the models that pair well with these augers.
Voltage matters more than most buyers expect. A 12V drill is fine for the smallest 1.6 inch auger in soft soil, but will bog down with anything larger than 2 inches. An 18V drill handles 2 and 3 inch augers in most soil types. For 4 inch augers and rocky ground, you want 20V or higher, ideally brushless. Torque ratings above 400 in-lbs are the threshold where augers stop stalling.
Drill chuck size also matters. A 3/8 inch chuck accepts both 3/8 and 1/4 inch hex shanks. A 1/2 inch chuck accepts 1/2, 3/8, and 1/4 inch hex shanks, giving you more flexibility for different augers.
Hole diameter and use case
Match the auger diameter to what you are planting. A 1.6 inch bit is ideal for crocus, tulip, and small bulbs. A 2 inch bit handles daffodils and small annuals. A 3 inch bit fits 1-quart to 1-gallon transplants and small shrubs. A 4 inch bit is the right size for fence posts, mailbox anchors, and umbrella bases.
Buying a single diameter is fine for focused work, but a small set (like the K-Brands 4-pack) covers more jobs. If you only buy one auger, a 3 inch bit is the most versatile general-purpose choice.
Length and ergonomics
Auger length determines whether you stand or squat. A 12-inch bit means you kneel or bend for every hole, which is fine for short sessions but punishing for big projects. A 16 to 18 inch bit keeps the drill closer to waist height. A 24 to 32 inch bit lets you stand fully upright while drilling.
Stand-up augers like the SORANGEUN 32-inch and Power Planter 3×24 are real back savers for big planting days. The trade-off is reduced control, since longer bits flex more and require steadier downward pressure.
Soil type and prep
Sandy and loamy soil are easy on augers and drills. Clay is where augers earn their keep, but it also burns out weak drills fastest. For heavy clay, pre-water the bed the night before to soften the top 6 inches, then drill in short bursts with the drill on a low torque setting.
Rocky soil requires technique. Stop the drill the moment you feel a hard thunk. Forcing through rocks bends shafts and rounds off hex shanks. For deep post holes in rocky ground, a gas-powered earth auger is more appropriate than any drill auger on this list.
Material and finish
Carbon steel is affordable and cuts well, but it rusts quickly and dulls faster in rocky soil. Alloy steel is the standard for most quality augers, balancing toughness and edge retention. PCM steel is a premium option that holds up best in abrasive soil. Stainless steel is rare in garden augers and usually overkill.
Finish matters for storage life. Black oxide is functional but minimal. Powder coating is thicker and resists rust better. Glossy enamel is the most rust-resistant and easiest to clean. After each use, wipe the bit dry and store it indoors to extend its life.
Safety and technique
Garden augers can twist violently when they catch a rock or root. Hold the drill with both hands, use a drill with a side handle when possible, and keep your drill’s safety clutch engaged. Wear gloves and eye protection. Drill in short bursts rather than continuous runs to avoid overheating both the auger and the drill motor.
Pre-mark your planting grid with stakes or flags so you do not lose count mid-bed. If you hit resistance that does not clear after a second or two, pull the auger out and clear the hole by hand before continuing. Trying to power through buried debris is the fastest way to wreck an auger and a drill.
Frequently Asked Questions
What is the best drill auger for planting?
The TCBWFY 2-Piece Garden Auger Set is our top pick because it includes two diameters (1.6 and 3.5 inch) that cover most bulb and bedding work. It uses a standard 3/8 inch hex drive that fits any cordless drill and is rated by more than 14,000 reviewers.
Do garden auger drill bits work?
Yes, garden auger drill bits turn any standard cordless drill into a fast hole-digger. They use spiral flighting to pull soil up and out of the hole, replacing 10 minutes of hand digging with about 10 seconds of drilling. They work best with 18V or higher drills in loam or clay soil.
What is a good garden planting auger tool?
A good garden planting auger has a hex drive (3/8 or 1/2 inch) that fits standard drill chucks, alloy or PCM steel construction for durability, and powder-coated or enamel finish for rust resistance. Look for a brand with hundreds or thousands of verified reviews and a stated warranty.
What is the best soil auger for gardening?
The best soil auger for gardening depends on your soil type. For clay and rocky ground, choose a heavy-duty model like the Power Planter DIY Guru. For loam and sandy soil, lighter budget picks like the MAXCCINO 2-inch work well. Match auger diameter to what you plant: 1.6 inch for bulbs, 3 inch for bedding plants, 4 inch for posts.
What are the common problems with drill augers?
The most common problems with drill augers are augers twisting out of the chuck mid-hole (caused by worn hex drives), drill motors burning out from extended use, augers stalling in hard clay or rocky soil, and shafts bending or breaking when forced through buried debris. Use a non-slip hex drive, a drill with adequate voltage, and stop the moment you feel resistance.
Why won’t my auger dig into the ground?
An auger that will not dig usually has one of three causes. The soil is too hard and dry, so pre-water the area and try again. The drill lacks torque for the auger diameter, so step down to a smaller bit or upgrade to an 18V or 20V drill. The hex drive is rounded off, so replace the auger with a non-slip hex drive model.
What are the disadvantages of using an auger?
The main disadvantages of using a drill auger are the risk of wrist injury when the bit catches on a rock, drill motor burnout from extended heavy use, and limited digging depth compared to gas-powered earth augers. Augers also struggle in very rocky or root-filled ground where you need a manual post-hole digger.
Can I use a Power Planter with any drill?
You can use Power Planter augers with most cordless drills, but the smaller DIY Guru uses a 3/8 inch hex drive that fits standard chucks, while the extended 3×24 model uses a 1/2 inch hex drive that requires a drill with a 1/2 inch chuck. Power Planter recommends 18V or higher drills for the best results, especially in clay soil.
Final Verdict
After six weekends and hundreds of test holes, the TCBWFY 2-Piece Garden Auger Set remains our top recommendation for the best garden augers for drills. The two-diameter set covers the widest range of planting tasks, the alloy steel has held up to repeated use, and the 3/8 inch hex drive fits any standard cordless drill without adapters.
If you want a single upgrade pick for clay and tough soil, the Power Planter DIY Guru 3×12 is worth the premium. Its lifetime warranty and family-owned American manufacturing are matched by performance that beats cheaper augers in real working conditions. For gardeners on a tighter budget, the MAXCCINO 2-inch auger offers most of the planting functionality at a fraction of the cost.
Match the auger to your drill, your soil, and what you actually plant, and you will save hours of digging this season. For more gear to round out your cordless setup, see our picks for the best compact cordless drills that pair with these augers.
