Our take on the Powermate 3/8 in. Butterfly Impact Wrench

The Powermate 3/8 in. Butterfly Impact Wrench is a compact pneumatic wrench with a butterfly throttle, a 75 ft-lb torque ceiling and a built-in air regulator. At 2.3 lbs and 6.5 inches long, it is built for tight spots where a full-size impact gun will not fit. Its best new price is $38.07 at eBay as of November 4, 2026, with four stores listing it new. That is near the bottom of what this tool has sold for recently, so the price is not a reason to wait.

Pros
  • Compact 6.5 in. body reaches confined spaces
  • Butterfly throttle gives fine control with one hand
  • Built-in air regulator adjusts power at the tool
  • Only 2.3 lbs, so it is easy to hold overhead
  • Three speed settings
  • Low price for a pneumatic impact
Cons
  • 75 ft-lb is modest; lug nuts and rusted bolts will resist
  • No sockets or accessories included
  • Needs a compressor and air line, so no cordless use
  • No impact-per-minute figure published, which makes blow count unclear
  • 2.9 out of 5 from 9 ratings is a weak owner score

Questions and answers

Is the Powermate butterfly impact wrench worth it?
For light work in tight spaces at about $38, yes. It will not break loose lug nuts or heavy suspension bolts, so do not buy it as your only impact wrench.
How much torque does it make?
Powermate rates it at 75 ft-lb maximum. That suits small fasteners, bracket bolts and assembly work, not automotive lug nuts.
Does it come with sockets?
No. The tool ships with no additional components or accessories, so you need to buy 3/8 in. impact sockets and a compatible air fitting separately.
What compressor do I need to run it?
It is a pneumatic tool, so you need a compressor and air hose with standard fittings. A small portable compressor can run it for light, intermittent use, but continuous work needs more air volume.
How does it compare with a full-size 1/2 in. impact wrench?
It is smaller and lighter but far weaker. A 1/2 in. gun typically delivers several hundred ft-lb, while this one tops out at 75 ft-lb.
When is the best time to buy it?
The best new price was $38.07 at eBay as of November 4, 2026. That is already low for this tool, so waiting for a deeper cut is unlikely to pay off.
