Review: Great but, worked really well - I needed to drill some 1-1/2" holes in a cinder block retaining wall. I tried the diamond tip hole saws. Those were terrible. Kept binding, really slow cut. I kept the tool wet and it took over an hour to cut one hole. The holes was really clean and professional looking, but I was exhausted after just one. Switch to this guy and a cheap rotary hammer ($150 from a chain discount tool place), and I punched 10 holes in the same amount of time. I kept the tool wet so it would stay cool and keep a sharp edge longer. I was still pretty tired after an hour of work, but now I'm halfway done with the project.

### ⭐⭐⭐⭐⭐ Great bit.
*by J***E on August 23, 2025*

This 1.5” x 21” bit is a beast. I spent more on it because of the tungsten carbide tip but it was worth it. Drilled almost 20 holes 16” deep for using with Dexpan product (expansion grout for demolition) on some poured concrete stairs. There were a few times I hit metal in the concrete, but this bit went through it. The tip still looks great. Well worth the money.
