*by K***S on August 29, 2014*

Works GREAT - does what is needed although the red clay mud can clog it at times. Excellent buy it was $300 cheaper than buying one locally.

### ⭐⭐⭐⭐⭐ Well made drill bit.
*by S***T on January 26, 2023*

Bores holes in basalt rock - off label use but what I needed to do. Holes need frequent cleaning, but it did the job, 20+ 18 inch deep holes and still working fine.
