M35 Cobalt Drill Bit Set | High-Speed Steel for Metal & Stainless Steel

Engineered for demanding tasks, the SLUGB Cobalt High Speed Steel Twist Drill Bit M35 Tool Set delivers superior performance in hard materials. The M35 cobalt steel alloy (5% cobalt) provides exceptional heat resistance and edge retention, significantly outperforming standard HSS bits when drilling stainless steel, alloy steel, and other tough metals. Features and Benefits - M35 Cobalt HSS Construction (5% Cobalt) - Offers superior heat resistance and hardness, maintaining a sharp cutting edge longer than standard bits for consistent, clean holes in hardened materials. - 135-Degree Split Point Design - Ensures precise starting without walking or skidding, reducing setup time and improving accuracy on curved or angled surfaces. - Optimized Flute Geometry - Efficiently channels chips away from the cutting edge, preventing clogging and reducing heat buildup for smoother, faster drilling. - Black Oxide Surface Treatment - Provides enhanced corrosion resistance and additional lubricity, reducing friction and extending the overall service life of the bits. - Complete Range of Sizes in a Durable Case - A comprehensive selection of commonly used diameters ensures you have the right bit for the job, all securely organized for protection and portability. Applications - Professional Metal Fabrication - Ideal for workshops and job sites requiring reliable, repeated drilling in stainless steel plates, structural steel, and high-tensile alloys. - Automotive and Machinery Repair - Perfect for drilling hardened bolts, exhaust components, engine brackets, and other tough metals encountered in maintenance and restoration. - DIY Home and Workshop Projects - An excellent choice for enthusiasts tackling metalworking projects, from building furniture frames to installing fixtures in metal studs. - HVAC and Plumbing Installation - Effectively drills through stainless steel pipes, ductwork, and brackets commonly used in commercial and residential systems. Note For optimal performance and longevity, use a sturdy drill press or powerful handheld drill at appropriate RPMs and apply consistent cutting fluid when drilling stainless steel or other hard alloys.
