Questions about this product
- Can these drill bits cut stainless steel?
- Yes, that's what they're built for. The M35 cobalt high-speed steel handles stainless and other hard metals where standard HSS bits dull fast. The 135 degree point angle is the usual choice for stainless drilling.
- What makes cobalt bits better than regular HSS for metal?
- These are M35 cobalt steel, hardened to roughly 65 to 67 HRC. The cobalt content lets them keep an edge at the higher heat that hard metals produce. That means more holes per bit before they wear out.
- Will these fit a standard drill chuck?
- Yes. They're straight-shank twist drills, so the shank matches the drill diameter and clamps in any standard keyless or keyed chuck. Use a steady speed and cutting oil for the best life in stainless.
