Bought this set mainly for the 1-1/8" cutter and it went through my metal electrical box like it was nothing. The three sizes cover pretty much everything I need for conduit work, and the carbide tips still look sharp after a dozen holes.

The carbide tips cut through 16-gauge steel way faster than the bi-metal saws I used for years, and the 7/8" one was perfect for my door lock install. Three sizes in one set for this price is a solid deal.

Bought these to cut through some 22 gauge sheet metal and the carbide tips sliced through way cleaner than my old bi-metal saws. The 7/8" size was perfect for my project, and honestly all three cutters feel solid in the drill.
