Hmm, never thought about it Mac... tho’ this stolen from Wikipedia..“ An impact wrench (also known as an impactor, impact gun, air wrench, air gun, rattle gun, torque gun, windy gun) is a socket wrench power tool designed to deliver high torque output with minimal exertion by the user, by storing energy in a rotating mass, then delivering it suddenly to the output shaft. It was invented by Robert H. Pott of Evansville, Indiana.”[/quoteIn that case we agree a rattle gun is a great tool - it removed all my clutch casing screws easily. Mine has two torque settings for tightening but it defaults to maximum when undoing anything. I only use the tightening mode for wheel nuts - always using a torque stick - they are a clever invention for impact drivers.
Personally i wouldnt use a "rattle gun" on hillips screws only on nuts and bolts plus the odd spinning allen screw in bottom of fork leg.I do have a 3/8 drive air impact gun from when i was in the trade but havent used it for years as i dont have a compressor
