Review on Premium Wet Drill Core Bits For Concrete And Hard Masonry - 10Mm Segment Height, 12" Drilling Depth, 5/8"-11 Arbor - Ideal For Wet Drilling Only by Randy Albright

Revainrating 3 out of 5

Did the job for my opinion

Drilled through 20" thick Pennsylvania ironstone wall for sewer line.

Used plenty of water but the grit on the bit is almost gone.It was a tough job and worth the cost.It would probably really hold up well for standard thickness concrete.

Pros
  • Did the job I needed to do. 17 1/2 X 2 inch hole in solid granet. Hell yea !!!!!
Cons
  • Can be difficult to control during drilling, increasing the risk of mistakes or accidents
