Product Details
Industrial M35 Cobalt HSS Twist Drill Bits (DIN338 Standard)
Uncompromising Drilling Power Manufactured to Exacting International Standards
When penetrating hardened metals, precision and thermal resistance are everything. The M35 Cobalt Twist Drill Bits from Shanghai Daoge Xiaoman Tools Co., Ltd. are strictly manufactured to German DIN338 specifications, ensuring perfect concentricity and reliable jobber-length performance. Forged from advanced M35 High-Speed Steel enriched with a 5% Cobalt alloy, these bits feature exceptional "Red Hardness." This metallurgical advantage allows them to effortlessly bore through Stainless Steel (Inox), Cast Iron, and abrasive metal plates without dulling under extreme heat. Designed with an aggressive 135-degree Split Point, they start cutting instantly without wandering, eliminating the need for center punching. Featuring a standard straight shank and an industrial amber finish for improved lubricity, these drill bits are the ultimate B2B consumable for heavy-duty fabrication and assembly lines.
Key Technical Advantages
- DIN338 Precision Compliant: Manufactured to strict international dimensional tolerances. Ensures a flawless fit in all standard drill chucks and provides predictable, highly accurate hole diameters.
- M35 5% Cobalt Alloy: The embedded cobalt delivers extreme heat resistance, vastly outperforming standard HSS-4241/4341 bits when tackling high-tensile strength alloys and stainless steel.
- 135° Split Point Technology: The self-centering cross-grind significantly reduces operator fatigue by lowering the thrust force required to penetrate the metal, while preventing the bit from "skating" on smooth surfaces.
- Industrial Amber Finish: The specialized oxide layer not only identifies it as a premium cobalt bit but also acts as a porous surface to hold cutting fluids, reducing friction during deep-hole operations.
- Massive B2B Manufacturing Capacity: We supply a complete metric sizing matrix (from 1mm to 13mm and beyond). Available in bulk industrial tubes, retail blister cards, or custom-branded assortments tailored for your distribution network.
