What is the difference between an impact driver and a drill?

A drill uses continuous rotation and a clutch for screw driving and is better for drilling holes. An impact driver uses rotational impacts (concussive blows) to drive screws with much more torque while being easier on your wrist. Most builders carry both.

Can I drill holes with an impact driver?

You can drill small holes in wood with hex-shank drill bits, but impact drivers are not ideal for precision drilling. The impact mechanism makes it hard to control depth and diameter. Use a drill for holes.

What are impact-rated bits and why do I need them?

Impact-rated bits (also called torsion bits) are made from flex-tempered steel that absorbs the hammering forces. Standard bits are brittle and will snap under impact. Look for bits labeled 'impact ready' or 'torsion zone.'

Drills & Drivers

$50-$100 for 12V kits, $80-$150 for basic 18V/20V, $130-$250 for brushless models, $200-$350 for premium multi-speed kits.

An impact driver delivers rotational force combined with concussive blows to drive screws and tighten fasteners with astonishing speed and power. Unlike a drill, which relies solely on rotational torque, the impact mechanism delivers hundreds of quick bursts per second that prevent wrist strain while powering through the toughest fasteners. Once you use one, you will never go back to driving long screws with a standard drill.

Key Takeaways

Unlike a drill, which relies solely on rotational torque, the impact mechanism delivers hundreds of quick bursts per second that prevent wrist strain while powering through the toughest fasteners.
Once you use one, you will never go back to driving long screws with a standard drill.
Impact drivers are used for driving long deck screws, lag bolts, and structural screws, assembling framing and sheathing, installing subfloor, building decks and fences, removing rusted or stuck fasteners, driving self-tapping metal screws, and any high-volume screw-driving task where speed and power matter.
Max torque (ft-lbs), impacts per minute (IPM), speed settings (1-4 modes), 1/4-inch hex chuck, brushless motor, compact length (under 5.5 inches), LED work light, battery platform compatibility, one-handed bit loading, and belt clip.

What It's Used For

Impact drivers are used for driving long deck screws, lag bolts, and structural screws, assembling framing and sheathing, installing subfloor, building decks and fences, removing rusted or stuck fasteners, driving self-tapping metal screws, and any high-volume screw-driving task where speed and power matter.

Types & Variations

Standard 1/4-inch Hex Impact Driver (most common), Compact/Sub-Compact (lighter, less torque), Oil-Pulse/Hydraulic Impact (quieter, less vibration), Multi-Speed/Multi-Mode (adjustable speed and torque settings), and Impact Wrenches (1/2-inch square drive for automotive use). Available in 12V and 18V/20V platforms.

and belt clip.

How to Use

1) Insert a 1/4-inch hex shank bit by pulling the collet forward and pushing the bit in. 2) Select the speed/power mode if available — low for delicate work, high for structural fasteners. 3) Position the screw on the tip and align with the driving point. 4) Start slowly to set the screw, then increase trigger pressure. 5) The impact mechanism engages automatically when resistance increases. 6) Control depth by releasing the trigger at the right moment — avoid over-driving. 7) Use impact-rated bits only — standard bits will shatter.

⚠️ Safety Tips

Wear safety glasses. Use only impact-rated (torsion) bits — standard bits can shatter under impact forces. Be prepared for the impact mechanism to engage suddenly. Impact drivers are loud — wear hearing protection for extended use. Do not use for drilling precise holes (use a drill instead). Keep a firm grip as the tool can twist when driving large fasteners.

Maintenance

Keep the hex collet clean and free of debris for reliable bit retention. Blow dust from motor vents. Inspect the anvil for wear. Follow battery care guidelines — store at 40-60% charge for long-term storage. Clean the exterior and keep moisture out of the motor. Replace the collet spring if bits no longer lock securely.

Price Range & Recommendations

Price Range: $50-$100 for 12V kits, $80-$150 for basic 18V/20V, $130-$250 for brushless models, $200-$350 for premium multi-speed kits.

Beginners should pair an impact driver with their cordless drill — the Ryobi ONE+ PCLI005B ($50 bare tool) or DeWalt DCF787 offer great value. For a combo, the Milwaukee M18 drill/impact kit is hard to beat. Pros will want the Milwaukee M18 FUEL 2953 (4-mode SURGE hydraulic) or DeWalt DCF850 (ATOMIC compact) for maximum control and power in tight spaces.
