Step Drill Bit Buying Guide

Cobalt Step Drill Bit

We will now go through the qualities and information you should consider while choosing the best cobalt step drill bit for you.


For whatever portion you buy, this is typical. The type of material used to produce a bit will influence whether it will damage the sheet or whether it will disintegrate first.

For step drill bits in thinner sheets like plastic, aluminum, and other soft metals, high-speed steels, or HSS, are excellent.

Yet for penetrating through tougher sheets, a stronger material, like cobalt, is needed. Yet, don’t fully blame the material if it doesn’t work because, more often than not, incorrect application is to fault.

Shank of a Drill Bit
