M35 Cobalt Drill Bits | 1-13mm Set | For Stainless Steel & Hardened Metal

Engineered for demanding metalworking, this 1mm-13mm Cobalt HSS Drill Bit set tackles hardened materials like stainless steel with superior heat resistance and durability. The M35 cobalt steel alloy maintains a sharp cutting edge longer than standard HSS bits, delivering cleaner holes and reduced bit wear under high-stress drilling conditions. Features and Benefits - M35 Cobalt HSS Steel - Provides exceptional heat resistance up to 1100°F, preventing premature dulling when drilling tough alloys and stainless steel. - 1mm to 13mm Size Range - Covers a versatile spectrum of hole diameters for precise fastening, tapping, and fabrication tasks. - 135-Degree Split Point - Ensures accurate positioning without walking, reducing skidding on curved or hard metal surfaces. - Full Flute Design - Efficiently evacuates metal chips to prevent clogging, reduce heat buildup, and ensure smoother drilling progress. - Premium Black Oxide Finish - Offers enhanced corrosion resistance and reduced friction for longer tool life and consistent performance. Applications - Stainless Steel Fabrication - Ideal for drilling clean, precise holes in 300 and 400 series stainless without excessive work hardening. - General Metalworking - Perfect for drilling through hardened steel, cast iron, and other ferrous metals in shop or garage environments. - Maintenance and Repair - A reliable choice for mechanics and technicians needing to drill out broken bolts or modify metal components. - DIY and Hobbyist Projects - Provides professional-grade performance for automotive, machining, or metal art projects requiring precision. Note For optimal results and bit longevity, use a sturdy drill press or hand drill at low to medium RPM with consistent, firm pressure and a suitable cutting fluid.
