Conquer the Hardest Metals with Industrial-Grade Precision. Stop struggling with burnt-out bits. Our M35 Cobalt HSS Drill Bits are engineered specifically for the toughest tasks. Whether you're drilling through grade 304 stainless steel or high-tensile alloys, these bits stay sharper longer and withstand extreme heat where standard HSS bits fail.

5% Cobalt Alloy (M35): Infused with 5% Cobalt to significantly increase heat and wear resistance. This is the gold standard for drilling hard materials.
135° Split Point Tip: Starts drilling on contact—no "walking" or center punching required. It cuts through metal faster and with less effort.
Fully Ground Geometry: Precision-ground flutes ensure efficient chip removal, reducing friction and preventing clogging during deep-hole drilling.
Gold Heat Treatment: The distinct gold finish isn't just for looks; it indicates a specialized heat treatment that enhances surface hardness and lubricity.
