These are great quality. Mine get used at work a lot and they cut great. I even used it in concrete a little bit. I still buy these, so much better than that Temu crap and as good as the Irwin stuff.

Quick and clean. Best one I’ve had. Made 100’s of enlarged holes and is still sharp. Hope it lasts.

This bit worked perfectly for cutting a hole in a stainless steel sink. It was easy to install into a drill and cut with ease. I gave it 4 stars because it go really hot and started to smoke so I had to wait a bit to finish my cut. That did not take away from the functionality though.

A pesar de haber habido un error en el primer envÃo, èste fue corregido a tiempo y ya me llegó mi pedido tal cual como aparece en la descripción. Solo falta probarla para mirar que tan buena es. Muchas graciasYa la utilicé y me parece genial, no tengo que hacer mucha fuerza, perfora muy fácil y rápido.

They worked great but didn't last long.Yes I did use oil as I drilled.The 1/16"-1/2" bit broke while drilling the 6th hole. A piece of the drill bit stayed in the channel iron, I then switched to the 1/8"-3/4" bit and drilled up to 3/8", long story short... the 3/8" size is now burnt and rounded.
