Customer Reviews

Hex Extensions,3/8 In is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from I bought this to use as a drill extension which is to say that I wanted an extension with a .375" hole to fit a .375" bit. The hole is .400" in diameter so when the drill is installed it is off set and unable to run true. The set screws/Allen wrench was also of poor quality and would not properly tighten up, but rather would slip before adequately tightening the bit in place. Just a piece of junk if you want something accurate, you better make it yourself.
