Buying Guide

Choose the right material

M35 cobalt handles stainless and hardened steel better while HSS is fine for softer metals and general-purpose work

Consider coating benefits

Titanium or TiAlN coatings reduce friction and extend life on softer metals but don’t replace cobalt for very hard alloys

Look at step range and counts

Fewer, larger steps suit big holes; multi-step sets with many increments provide more versatility for varying hole sizes

Check flute design and shank type

Spiral or double-fluted bits clear chips faster; hex or 3/8" shanks improve grip in impact drivers and quick-change chucks

Match bit size to tasks

Select individual larger-capacity bits for heavy sheet metal work and compact sets for light fabrication and electrical holes

Prioritize durability over low cost

A slightly higher upfront cost for cobalt or high-quality coatings usually yields longer life and fewer broken bits on tough materials
