CertBuy 2 1/2 Inch Concrete Hole Saw with SDS Plus Shank, 65mm Wall Hole Saw Drill Bit for Brick Concrete Cement Stone

The shank, bit and drill were all very sturdy looking. I was surprised how it went through 2 rows of cinder block in the wall. This drill bit made the oil tank piping install easier than I thought it would be. Good quality, fast delivery.

I want to install a 2 inch pipe to drill 2 inch hole through the concrete. Find 2 inch is not enough so exchange this 2 1/2 inch. I use normal electric code driller with this tool to make hole trace. Next, I use 3/16 inch concrete bit drill 8 holes around maker and the center hole after that I switch 1/2 inch bit to enlarge these holes. Finally, I put this tool it so easy to finish the job.

This is a good tool for cutting into brick and cement block. Don't push it to hard, let the tool do the work. I would highly recommend putting Loctite on the screw that hold the bit in place. It will come off

Good quality and heavy duty for the price. It drilled thru 8 inches of poured concrete. Slow but will get it done.

Worked great for drilling some holes in cindeblock to run intake and exhaust PVC for my new water heater. Drill bit still looks healthy and Im sure I could get much more use out of it.

worked as advertised and handled concrete well if water added to help cutting

Worked well, but labeled not for use on hammer drill

Perfectly drills a hole in stucco!
