HSS Cobalt Twist Drill Bit Set – Multiple Sizes For Stainless Steel & Hard Metals

Drilling through stainless or hardened steel?

You need bits that won’t give up halfway through.

This HSS cobalt drill bit set is built for tough materials.

You can pick the size range that works for you — whether it’s 4-10mm, 1-10mm, or 1-13mm.

These are twist drill bits, so they’re perfect for general purpose metal drilling, but the cobalt content means they stay sharp longer and handle heat better.

Brand new, still in the packaging, and unbranded so you’re paying for performance, not a name.

They’ve got a self-centering tip too, so they start clean and don’t wander.

If you’re a machinist, fabricator, or just a DIYer who works with metal, this set belongs in your toolbox.
