Best Wood Drill Bit Sets for Drilling Stainless Steel (2026)

We selected sets based on bit material (M35 cobalt or M2 HSS), shank design, size range, user ratings, and overall value for drilling stainless steel

This roundup evaluates wood drill bit sets that perform well when drilling stainless steel, focusing on material, shank compatibility, and value. Picks were chosen by comparing bit material (M35 cobalt, M2 HSS), shank types, and user ratings to identify sets that balance durability and compatibility with wood-focused toolkits

Buying Guide

Choose the right bit material

Cobalt alloys (M35) and high‑speed steels (M2 HSS) resist heat and retain edge when penetrating stainless steel better than standard carbon steel bits

Match the shank to your driver

Hex, triangle and quick‑change shanks affect grip and compatibility with chucks and impact drivers; pick a shank type that fits your existing tooling

Consider bit geometry and purpose

Step drill bits are suited for hole enlargement and thin metals, while twist cobalt bits handle through‑holes in thicker stainless reliably

Prioritize set range and sizes

A broader size range (fractional or metric) reduces the need to sharpen or swap bits when working across different fastener or hole size requirements

Weigh durability versus cost

Higher‑grade cobalt or HSS sets cost more but last longer when drilling hard metals; budget sets can be fine for occasional use if heat control is practiced
