Drill vs Impact Driver: Which Do You Actually Need?
By Holt C. Bridger · Updated May 26, 2026 · 8 min read
TL;DR
- Drill — Precision holes, small screws, adjustable clutch, most versatile.
- Impact driver — Long screws, lag bolts, dense wood, 3x the torque.
- Verdict — Most people need both. If you can only buy one, start with a drill.
Key Differences at a Glance
| Feature | Drill | Impact Driver |
|---|---|---|
| Chuck | 3-jaw (1/2" or 3/8") | 1/4" hex collet |
| Typical Torque | 400–700 in-lbs | 1,500–2,200 in-lbs |
| Torque Delivery | Smooth, constant | Rotary impacts (bursts) |
| Adjustable Clutch | Yes (prevents over-driving) | No |
| Speed | 0–2,000 RPM | 0–3,200 RPM + 3,800 IPM |
| Noise | Quiet whine | Loud rattling (ear protection recommended) |
| Best For | Drilling holes, small fasteners, precision | Driving long screws, lag bolts, deck screws |
| Bit Compatibility | Any round-shank bit | Only 1/4" hex-shank bits |
| Price (bare tool) | $80–150 | $100–170 |
When to Use a Drill
A drill/driver is the most versatile power tool most people will ever own. Its 3-jaw chuck accepts any round-shank bit — drill bits, spade bits, hole saws, driver bits, mixing paddles. If you own one power tool, this is it.
Best drill tasks:
- Pilot holes for screws (prevents splitting)
- Through-holes for bolts and dowels
- Driving small screws (#6–#10) into softwood
- Installing cabinet hardware and hinges
- Mixing paint, thinset, or joint compound (with paddle bit)
- Any task where you need precise depth control
The adjustable clutch is the drill's killer feature. Set it to a low number and the drill slips at a consistent torque — no more over-driving screws into drywall or snapping screw heads off in hardwood.
When to Use an Impact Driver
An impact driver does one thing extremely well: driving fasteners with brutal efficiency. Its internal mechanism delivers rapid rotational strikes (1,500–3,800 impacts per minute) that push screws through dense materials a drill would struggle with.
Best impact driver tasks:
- Deck screws (3" and longer) into pressure-treated lumber
- Lag bolts and structural screws
- Long screws into hardwood or studs
- Tightening or removing stubborn bolts (within torque range)
- Building fences, sheds, and framing
- Any repetitive screw driving (far less wrist strain)
The impact mechanism means you feel almost no torque in your wrist — the tool absorbs it internally. This makes all-day screw driving dramatically less fatiguing.
Common Mistakes
✗ Don't Use an Impact Driver For
- Precision drilling (bit wobble in hex collet)
- Small delicate screws (cam-out and stripping risk)
- Drywall screws (no clutch = over-driven)
- Removing lug nuts (not enough torque — use an impact wrench)
✗ Don't Use a Drill For
- 3"+ deck screws (will stall or strip)
- Lag bolts into hardwood (will burn out the clutch)
- Repetitive heavy fastening (wrist fatigue)
- Removing seized bolts (impact mechanism needed)
Our Honest Recommendation
If you only buy one tool:
Get a drill. It handles 80% of what most homeowners need. The adjustable clutch prevents damage, the chuck accepts any bit, and it drills holes (which an impact driver does poorly).
If you do regular DIY or any carpentry:
Get both. A mid-range 18V/20V drill + impact driver combo kit costs $150–200 and covers virtually every fastening task. Buy into one battery platform (DeWalt, Milwaukee, or Makita) so the batteries interchange.

Frequently Asked Questions
Can I use an impact driver as a drill?
Yes, with a hex-to-chuck adapter you can use drill bits in an impact driver. However, the lack of a traditional chuck means bits can wobble, and the higher torque can damage delicate materials. For precision drilling, a dedicated drill is better.
Do I need both a drill and an impact driver?
If you do more than occasional DIY, yes. A drill handles pilot holes, small screws, and precision work. An impact driver handles long screws, lag bolts, and dense materials. Together they cover 95% of fastening tasks.
Why does my impact driver keep stripping screws?
Impact drivers deliver torque in bursts (impacts). If the bit doesn't fit the screw head precisely, those bursts can cam out and strip. Use high-quality bits, apply firm forward pressure, and start slowly before the impacts engage.
Which is better for a beginner?
Start with a drill. It's more versatile, easier to control, and less likely to damage materials or strip screws. Once you're comfortable and find yourself driving lots of long screws, add an impact driver.
Can an impact driver remove lug nuts?
A standard 18V/20V impact driver (1,500–2,000 in-lbs) usually can't break lug nuts free (typically torqued to 80–100 ft-lbs). You need an impact wrench, which delivers 3–5x more torque. Don't confuse impact drivers with impact wrenches.
