Impact Drivers compared

An impact driver drives long screws and lag bolts that stall a drill. It takes 1/4" hex bits, not round drill bits. Here is every major brand at the same tier, side by side, from each brand's own spec pages.

Manufacturer-published specs. Not our tests. Copied from each brand's own product pages, accessed 2026-10-29. We never rank them or pick a winner from specs.

Entry / DIY

Weekend projects, repairs around the house, a few jobs a month. Lighter and lower cost.

Pro / flagship

Daily use, bigger bits and blades, tougher material. More power, usually more weight and cost.

Pick your battery first

Batteries only fit tools from their own brand line. If you already own batteries, compare inside that brand first.

Entry / DIY brushless

Ryobi ONE+ HP, Craftsman V20 brushless, Ridgid 18V brushless, DeWalt ATOMIC/XR, Milwaukee M18 brushless, Makita 18V LXT brushless, Bosch 18V brushless. Bare tool, no battery.

In-lbs only, as published. UWO/MWO ratings are in the tables, not charted. Brands rate torque and power differently: in-lbs (Milwaukee, Bosch, Ridgid, Ryobi), in.lbs/N·m (Makita), and DeWalt and Craftsman often publish UWO (Unit Watts Out), and MWO (Max Watts Out) for some tools, instead of torque. UWO and MWO are not torque, so they're shown as text and never charted against in-lbs. Even in-lbs figures come from each brand's own test method, so a taller bar doesn't mean a stronger tool.

Brands publish weight on different bases: tool only, with a battery (which battery varies), or unstated ("Assembled Product Weight", "Product Weight"). Each bar is tagged with its basis. Only compare bars that carry the same tag.

Length bases differ (overall length, tool-head length, or a plain 'Length' field). Each bar is tagged. Assembled or package-style dimensions aren't charted.

What the specs mean

Torque (in-lbs)

Fastening force. Higher figures help with lag bolts, but brands test it their own way.

Impacts per minute (IPM)

How many rotational hits per minute once the screw starts to resist.

No-load speed (RPM)

Top spin speed. Multi-speed drivers let you slow down for small screws.

How to read these tables

  • Values are copied as published. Nothing is estimated, averaged or converted. "not published" means the manufacturer page didn't list it. Bars are in fixed alphabetical brand order. There's no ranking and no winner.
  • Brands rate torque and power differently: in-lbs (Milwaukee, Bosch, Ridgid, Ryobi), in.lbs/N·m (Makita), and DeWalt and Craftsman often publish UWO (Unit Watts Out), and MWO (Max Watts Out) for some tools, instead of torque. UWO and MWO are not torque, so they're shown as text and never charted against in-lbs. Even in-lbs figures come from each brand's own test method, so a taller bar doesn't mean a stronger tool.
  • Brands publish weight on different bases: tool only, with a battery (which battery varies), or unstated ("Assembled Product Weight", "Product Weight"). Each bar is tagged with its basis. Only compare bars that carry the same tag.
  • Length bases differ (overall length, tool-head length, or a plain 'Length' field). Each bar is tagged. Assembled or package-style dimensions aren't charted.
  • Grey text under a value shows where on the page it came from (if not the spec table), or that the brand doesn't say what the weight includes.
