Questions about this product

Will these drill bits actually cut through stainless steel?
Yes, that's exactly what they're built for. The M35 cobalt steel handles stainless, hardened steel, and cast iron without losing its edge. They're a solid pick for fabrication and tough alloy work in a metal shop.
How much heat can these cobalt bits take before they go dull?
They hold up to roughly 600°C (1112°F), which is why they stay sharp drilling hard metal. Keep your speed moderate and use a little cutting fluid on stainless to push that lifespan further. Pushing too hard or running dry will still burn any bit.
Do I need to center punch before drilling with these?
No, the 135-degree split point starts on its own without wandering. That saves you the center-punch step and gives cleaner, more accurate holes. Just line up the tip and let the bit bite.
