Butterfly Impact Wrench

[ServiceWithIntegrity]

Does anyone on the forum know what is the most powerful 3/8 in. drive butterfly impact wrench offered on the market?

Just curious ... can anyone explain the purpose of these butterfly impacts and what advantage they have over standard types or ratchets?

Well, for working at ankle level, like on a motorcycle engine not on a lift, the ergonomics are better than a pistol grip style impact..

Great for transmission valve bodies.

by a used CP 725, they have both pistol grip and butterfly styles and they are great.

I have the Craftsman. It works just fine for me.
95 ft/lbs of torque. The price is right too..

Being an impact type, they don't kick back like a conventional ratchet. The one cited above also has a higher ft-lbs than most ratchets.
