5.0 out of 5 stars Great bit, not designed to drill rebar, needs to be used properly, be smart it will last
Reviewed in the United States on November 6, 2018
Size: 5 In DiameterStyle: 22-In LengthVerified Purchase
This bit and others I have purchased like it work as they should. These bits will not drill dozens of holes in old concrete. Your lucky if you get 5 or 6 holes out of one bit. The pilot bit may break or the retainer pin may break or fall out, this is not necessarily a failure caused by a defect in the bit. This bit is not magic, it drills holes in concrete of many different designs. It will drill through steel rebar but needs to be done carefully and dulls the bit significantly, so use a rebar cutting bit at these areas if you can. It frustrates me to see people give three stars or less for this bit as it is worth every penny and I consider myself lucky to have access to these. These drill bits are money makers if you bid your job correctly. Just my opinion.

Perfect for core drilling block to run pvc pipe through. Being a plumber, having to chip a hole through block to run pipes through underground is terrible. With this bit you simply drill a perfect hole, slide a sleeve through the block. Slide the pipe through the sleeve and you’re done. Great product. On hole #40 and still cuts great.

This was a great purchase! I couldn't imagine going back to my old way. I used to drill a dozen smaller holes and chisel out my 5 inch cores. This hole saw leaves a very clean hole in concrete, this makes for a perfect fit. Just make sure you use something else if you run in to rebar

How to drill a 4-in hole in brick and then 3 in in concrete, this thing made a perfect hole very clean no issues but the teeth are already ground down after only one hole would probably work for a few more but at that price I would like it to last longer or to be cheaper.
