Cobalt Twist Drill Set | HSS Core Bits for Metal Drilling | Stainless Steel & Wood Cutter

This HSS M35 cobalt-coated twist drill bit set is a core component for any workshop, offering reliable performance across diverse materials. The cobalt enhancement provides extra durability for metal, while the precise engineering ensures clean, efficient holes in wood, making it an essential, versatile tool set. Features and Benefits - M35 Cobalt HSS Alloy - Combines 5% cobalt for superior red-hardness, allowing the bits to maintain a sharp edge at high temperatures during prolonged use. - Titanium Nitride Coating - Reduces friction and heat generation, increases lubricity, and provides a protective layer that significantly extends the service life of the bits. - Precision Ground Flutes - Optimized for efficient chip ejection to prevent clogging and ensure smoother drilling operations in both metal and wood. - Universal Shank Design - Compatible with a wide range of standard chucks on corded drills, drill presses, and cordless power tools from brands like DeWalt and Makita. Applications - Drilling pilot holes and clearance holes for fasteners in mixed-material assemblies and general carpentry. - Maintenance, repair, and operations (MRO) tasks in workshops for drilling into a variety of metals, including mild steel and aluminum. - DIY home projects and craft work requiring precise drilling in hardwood, softwood, and plastic composites.
