Buying Guide

Choose the right material

Cobalt bits resist heat and work well on stainless and hardened steels, while M2 HSS is adequate for general metal and wood drilling

Match shank to your chuck

Reduced shank bits let larger-diameter bits fit standard chucks; confirm the reduced shank diameter (for example 1/2") suits your drill or press

Check diameter availability

Sets cover common sizes; buy individual reduced shank cobalt bits if you need a specific large diameter rather than an entire set

Look for coating and finish

Gold-oxide or other finishes can improve chip flow and corrosion resistance, useful for extended cutting life in tougher materials

Consider cost versus lifespan

Higher upfront cost for cobalt generally yields longer life when cutting hard materials, while budget M2 sets are cost-effective for occasional use
