Best Drill for Auger Bits: 18V or 60V?
| Auger size | Drill to use | Shop augers |
|---|---|---|
| 2"–3" | Standard 18V cordless drill. The hex is formed on the auger shaft, so no adapter is needed | 2" augers, 3" augers |
| 4"–5" | 18V cordless 1/2" drill with a larger battery (higher Ah) | Large Bulb Auger (4"), 5" augers |
| 7"–9" | High-torque 60V cordless 1/2" drill | 7" augers, 9" augers |
| Professional or daily use, any size | 60V cordless drill | Drill augers and bundles |
How to Choose a Cordless Drill for Augers
Go cordless: we recommend cordless drills only, for safety. Never use an impact driver with an auger.
Battery: for 4"–5" augers, choose an 18V 1/2" drill with a larger battery (higher Ah).
Check the chuck: 4" and larger heavy-duty augers ship with an adapter installed for a 1/2" chuck. If your drill has a 7/16" quick-change chuck instead, you need a 7/16" Quick Attach adapter: see our auger adapters.
Buy it together: our auger and drill bundles pair the right augers with a drill in one order.
For a full breakdown by auger, see our drill power guide.
FAQs
How do I attach an auger to my drill?
Open the chuck, insert the auger's hex shank (or the adapter on 4" and larger heavy-duty augers) and tighten the chuck firmly. Our guide shows how to secure a bit in your cordless drill the right way.
What is an auger drill?
An auger drill is a cordless drill fitted with an auger bit, a spiral bit for soil. Together they drill planting and post holes in seconds instead of digging by hand.
Does my drill have to be a certain brand?
No. What matters is the drill's voltage, chuck and battery for the auger size you choose, as shown in the table above.
