Bosch® Concrete Drill Bit - Carbide Tip - 12" is rated
Rated 1 out of
Broke within 5 hours
I purchased the bit to install a vent through my foundation and after about 5 holes, the bit became slower and eventually lost the tip. Unfortunately I can't bring it back to the store for a refund and the best I can do is buy another and hope it lasts or (more likely) change the plan.
