“I needed to cut a few holes in the back of some steel cabinets (about 1mm thick) to run electrical through. Cuts were quick and clean with this. Not the biggest challenge, but it did what it needed to. Based on how it was (included a tear down of the bit in the picture) it should work well as I need it. I like the plastic case, too, so it's easy to store in that "used on occasion" toolbox.”

Used this to cut 3/4” holes into two of my trailer frame to install lights and it did NOT disappoint. This chewed through it with plenty of cutting oil and drill speed on 1. I already had pilot holes drilled using a Milwaukee pilot bit and all other step drills just rounded off on me no matter the speed or oil amount. This thing….. impressed me. I don’t ever write reviews but this was impressive for a cheaper bit. It comes in a great storage case along with a replacement “pilot bit” or “mandrel bit”. Highly recommended.

This drill bit worked excellent. Drilled 20 holes in quarter inch steel no problems. The key is to moderately go slow and lots and lots of lubrication. The only thing I noticed with even my DeWalt electric drill it's just a little too much for the drill to handle if you have the option use a pneumatic drill says cooler. Would definitely recommend to anybody.
