I bought 2 of these! A little disappointed with the grip of the carbide tips but I must admit that I gave them a hard time!! When used in new condition, it performs very well but as it drops off the peaks, the performance decreases rapidly. I am still satisfied with his performance with what I put them through!

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.
