Customer Reviews

Impact Adapter,Impact Drivers,3/8 In is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from Don't use with a Hog Ring Impact I bought this adapter so I could use 1/4" hex bits with my Milwaukee M12 3/8" drive Impact Wrench. I had a difficult time installing the adapter over the friction (hog) ring on the anvil and then struggled to remove it. After a few attempts it seemed to loosen up a bit but then it tore the O-ring off from underneath the friction ring and it would longer hold onto sockets securely. The adapter works well with my other 3/8" ratchets that have a ball-type retainer but use caution with 3/8" drive ends that have a friction ring retainer. It's too bad because this adapter is rated for impact duty. However, the detents on the inner walls of the 3/8" drive end indicate this is not compatible with friction ring retainers. The product is well made, just poorly designed for the intended application. I had to by a $50 repair kit to replace the hog ring on my brand new M12 impact wrench. I also bought the 1/2" adapter, which is useless to me since it has the same issue.
