Buying Guide

Match bit material to workpiece

Choose cobalt for stainless steel and hardened alloys and HSS for softer metals and general-purpose drilling

Verify shank size and fit

Confirm the reduced shank diameter works with your chuck and consider round vs keyed shanks for your drill type

Pick set vs single bits

Sets with multiple sizes give flexibility for varied projects, while single cobalt bits target specific hard-metal tasks

Look for heat and wear resistance

Higher cobalt content and proper coatings improve heat tolerance and retain sharpness during prolonged use

Consider cost per usable hole

Evaluate durability and expected lifespan—cobalt bits often cost more upfront but reduce replacement frequency on hard materials
