SDR88702 - Irwin Tools Woodboring Drill Bit Extension

These things work great. I have 2 of them now and use one for a wire brush to clean diesel injector bores and the other has a roloc adapter on it. Both are used with my drill. The Irwin extension work way better than cheaper version because the set screws don’t tend to strip and the bit retention is very good compared to others

does the job

These work great to make an extension for a die grinder.

works perfect good quality

I ended up converting this extension into a adapter of sorts so I can use impact bits on a standard, regular drill. It works like a charm.
