1/2'' Shank TO 1-1/4''-7 (M) Adapter
- Product Review (submitted on August 31, 2013):
- Nicely finished. I used this adapter on a 3" x 16" dry core bit to drill 2 holes through a 12" brick wall. It worked as it was supposed to. I used anti-seize paste on the threads and it screwed right out at the end of the job.
