I purchased two of these bit to add some stub outs for a pre existing concrete foundation. I used them with my Bosch SDS-max drill. They drilled through the concrete effortlessly. The long shanks allowed me to drill all the way through the foundation. Take it, it was not a thick section of the foundation. About 6 inches thick. The bits did not dull cutting though 6 to 10 holes.

This cut a hole in my foundation like butter. Only issue for me was that the bit was just slightly too big for my hammer drill so I had to rent a larger one

Have had Milwaukee and Hilti bits last for years. This was an absolute waste of money. I had purchased end of November and just rotated it into inventory. Lasted 10 minutes. Past date of return.

I purchased to use to drill holes thru concrete, block and/ or stucco to install plumbing pipe and Bosch Bits are dependable.Since the shell tightens to the threads of the pilot shank, I use a small amount of heat proof grease on the threads which makes removal of the Speed Core a little easier.I had no trouble turning this bit using my Milwaukee Fuel M-18 Cordless Hammer Drill, just have to take your time.

Great core drill for concrete with metal mesh
Reviewed in the United States on September 26, 2020
Size: 3-1/4-Inch
Nice design, quick cutting, while absorbing most shock and vibration during operation. Made very cleanly-cut and accurately-sized holes through concrete, rocks, and metal mesh wires. Hope it stays nice and sharp for a few hundred holes.

This core drill cut through the old concrete foundation like butter! I expected to have to chisel out the central core. No, it made the 2" holes with just a pile of aggregate dust coming out. Worth every dollar!
