Yep, they're great. No doubt about it. But be very careful what they are used on. Ancient iron of unknown history can have head bolts or other CRITICAL/special bolts that mite look ok but could be rusted and siezed at der threads.

The impact can snap such bolts. Also be careful of forgetting to change direction of the impact thus snapping bolts.

The impact wrench is just fuine for the hired mechanic working on commision which means rather NEW or not real old cars and parts.

If u like the big 1/2 inch impct then try a 3/8 drive butterfly for smaller bolts.

I can only run about 125 psi on all 6 of my compressors and that is plenty.

Just don't get over confident with the impact wrench and ruin something that mite need some finess.

BTW, i knew very well Duntovs chief mechanic that put in 30 years at Chev hi-perf R&D at the Gm Tec-ccenter in warren. Knew him alll of my life. He NEVER owned nor used an impact wrench. From junk farm plowsto CERV I and CERV II among many others. Never used an impact. Didn't like them for reasons stated above.

I sure use the impact tho.
