Review on 🪚 Chiloskit 3-Piece Titanium-Coated HSS Steel Step Cone Drill Bit Set - Ideal for Drilling Holes in Metal/Wood - Sizes: 4-12/20/32mm by David Edwards

they are better than most brands i have bought and i ALWAYS buy them with the expectation that they will be destroyed after a few months but they have most other brands survived by 3 bits I only have one that I have to replace after a few years, the thick shank keeps them from breaking and the smaller steps seem to help keep them sharp longer
