Industrial M35 Cobalt HSS Twist Drill Bits (Metric Sizes)
The Ultimate Heavy-Duty Drilling Solution for Inox and Hardened Alloys
Consolidate your supply chain with the definitive drill bit series for extreme metalworking. The M35 Cobalt HSS Twist Drill Bits from Shanghai Daoge Xiaoman Tools Co., Ltd. are engineered to outlast and outperform standard high-speed steel in the most demanding applications. Formulated with a 5% Cobalt Alloy (M35), these bits boast remarkable "Red Hardness," maintaining a razor-sharp cutting edge even at the blistering temperatures generated when drilling Stainless Steel (Inox), Cast Iron, and abrasive alloys. Available in a complete Metric Size Matrix (1.0mm to 13.0mm, including the high-demand 6mm and 7mm variants), this jobber-length series ensures you have the exact diameter for any fabrication task. Featuring a precision 135-degree Split Point, these bits bite instantly into smooth metals without wandering. We support global B2B distributors with bulk tube packaging, custom metal index sets, and fully bespoke OEM branding.
Key Technical Advantages
- Complete Metric Coverage: Whether you need a 6mm bit for clearance holes or a full set from 1.0mm to 13.0mm, our comprehensive sizing matrix allows distributors to build complete catalogs from a single trusted manufacturer.
- M35 5% Cobalt Alloy: The cobalt blend provides superior heat resistance and durability. It cuts through 304 and 316 stainless steel effortlessly, offering up to 10X the lifespan of standard HSS bits.
- 135° Split Point Technology: The self-centering cross-grind eliminates the need for a center punch. It stops the bit from "skating" on hard surfaces and significantly reduces the thrust force required by the operator.
- Amber Oxide Finish: The distinct gold/amber surface treatment acts as a porous layer that retains cutting fluids, drastically reducing friction and heat buildup within the hole.
- Fully Ground Precision: CNC-milled from solid steel blanks, ensuring perfect concentricity, exact hole diameters, and highly efficient chip evacuation through the flutes.
