10pcs M35 Cobalt Drill Bits Set | For Stainless Steel & Metal | 1-3mm High-Speed Steel

This professional 10-piece set of HSS M35 Cobalt Drill Bits is designed for tackling tough materials like stainless steel and hardened metals. The 5% cobalt enhancement significantly increases heat and abrasion resistance, while the titanium coating reduces friction. The precise size range from 1mm to 3mm is ideal for detailed metalworking and precision tasks. Features and Benefits - M35 High-Speed Steel with 5% Cobalt - Offers superior red-hardness and durability, maintaining a sharp edge even under high-temperature drilling. - Titanium Coating - Reduces friction and heat generation, provides a harder surface for increased wear resistance and smoother drilling action. - Precision Sizes (1-3mm in 0.2mm increments) - Allows for exact hole sizing critical for tapping, assembly, and fine mechanical work. - 135-Degree Split Point - Self-centering design starts quickly without a center punch and minimizes walking on curved or hard surfaces. Applications - Drilling stainless steel, cast iron, and other hard metals in automotive and aerospace fabrication. - Creating pilot holes, clearance holes for screws, and precise openings in electronic enclosures and instrument panels. - General-purpose metalworking in workshops, ideal for repair jobs, model making, and DIY projects on tough materials.
