According to my experience, this rotary masonry bit is a game changer. It easily drills into concrete, brick, and other tough materials with precision and speed. The tip stays sharp even after prolonged use, allowing for clean and smooth holes every time.
Didn't work well after drilling the first part (bottom of the pot) it dulled very quickly and I know it was some kind of pot the masonry drill had to go through because a friend's drill bit it did work fine.
Used to install a sliding shower/bathroom door. DO NOT use to drill holes in door rails. It's not designed for that (yes, I found out the hard way after noticing the holes weren't round) -: Drills into ceramic tile and Duroc very well. Very straight cut. Went through like clockwork.
