Industrial M35 Cobalt HSS Twist Drill Bit for Stainless Steel
Unrelenting Cutting Power for the Most Demanding Metal Fabrication
When standard high-speed steel fails, the M35 Cobalt Twist Drill Bit from Shanghai Daoge Xiaoman Tools Co., Ltd. takes over. Specifically engineered for extreme metalworking, these drill bits are forged from an advanced M35 Alloy containing 5% Cobalt. This critical metallurgical upgrade provides extraordinary "Red Hardness," allowing the bit to withstand the intense heat generated when drilling through Stainless Steel (Inox), Cast Iron, and high-tensile steel plates without losing its sharp cutting edge. Equipped with an aggressive 135-degree Split Point, the bit centers instantly upon contact, eliminating drill "walk" and the need for center punching. The distinctive Amber/Gold Oxide finish isn't just cosmetic; it retains cutting fluids to further reduce friction. Available in bulk tubes or retail blister packs, this is the ultimate consumable for professional fabrication shops and industrial distributors.
Key Technical Advantages
- 5% Cobalt Formulation (M35): Unlike surface-coated bits, the cobalt is blended throughout the entire steel matrix. This means the bit retains its extreme heat and wear resistance even after multiple re-sharpenings.
- 135° Split Point Geometry: Reduces the required thrust pressure by up to 50% compared to standard 118° bits. The self-centering tip bites cleanly into smooth, curved, or hardened surfaces instantly.
- Superior Red Hardness: Will not warp, dull rapidly, or shatter under the high operating temperatures necessary to cut through 304 and 316-grade stainless steel.
- Precision Milled Spiral Flutes: Fully ground from solid metal blanks to ensure rapid, jam-free chip evacuation, which is critical when drilling deep holes in dense metals.
- Flexible Wholesale Sourcing: Whether you need mass quantities packaged in bulk plastic tubes for factory lines, or custom-branded retail cards for hardware stores, we provide end-to-end OEM manufacturing.
