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.

I don't use it often but always good to have on hand. Pulled it out last weekend lots of meat on the diamond carbide and spacing on the segments was good. Started freehand and sliced through 4" like butter. It as a good buy.

Only used it once so far works smoothly and efficiently

Arrived . I like the tool but I have not used in very demanding challenge so far
