Good addition to 7/16 Cordless Impact Driver

By fredC on May 28, 2014

Verified Purchase

I recently bought a Milwaukee M18-Fuel (2765-22) cordless impact driver and put it to use drilling pipe clearance holes with Milwaukee selffeed bits. The tool had power beyond my initial expectations - so I added this adapter to use it with impact sockets for driving big lags. Some other adapters were a bit cheaper - but I've always had good luck with Proto tools - and so far so good with this item.

Tool I needed

By Green Rider on April 3, 2015

Verified Purchase

I needed a heavy duty adapter to use with my drill and a 1/2-Inch Drive Ratchet Adapterr and this was heavy enough to do exactly what I needed it to do.
