1 1/2 Inch Wet Core Drill Bit, 1.5" Core Bits for Concrete, 14" Drilling Depth, 1-1/4"-7 Thread Diamond Core Drill for Cured Concrete, Hard Masonry, Brick, Solid Cement, Stucco, Stone (38mm)

We have started using these core bits with a hope and a prayer and so far they worked out extremely well for some large jobs that they have been used on. No complaints regarding quality or premature failure and we know core drills are highly abused on rentals on job sites. So far so good.

Good quality core bit. I used it for Coring holes for interlock project for landscape lights. Works good and did about 45 holes no problems. Good price and quality.

Awesome coring but for the price. I needed it to drill 8 inch concrete. Did the job good and still looks like you can drill another 10 holes. Took me 4 hours but it was mostly because my rotary drill was a little small and kept overheating.

Only used it once so far works smoothly and efficiently

Great core drill. 18 holes through an 8" block pored solid, and still has teeth at 50%. Half the price of name brand!!!
