Product Details
✓M35 COBALT DRILL BIT SET: This 6-piece metric cobalt drill bit set includes 5mm, 6mm, 8mm, 9mm, 10mm, and 12mm sizes for common metal drilling tasks. Straight-shank design makes the set suitable for workshop, maintenance, repair, and metal fabrication applications.
✓5% COBALT M35 HSS-Co: Made from M35 high-speed steel with 5% cobalt for improved hardness, heat resistance, and wear resistance compared with standard HSS material. The cobalt-alloy construction helps the cutting edges maintain reliable performance during demanding metal drilling.
✓135 DEGREE SPLIT POINT FOR ACCURATE STARTS: The 135 degree split-point tip helps the drill bit start more accurately with less walking on the workpiece surface. Combined with the spiral flute design, it supports smoother chip removal and more controlled drilling in metal.
✓FOR STAINLESS STEEL AND MULTIPLE METALS: Designed for drilling stainless steel, carbon steel, cast iron, copper, aluminum, and other compatible metals. Suitable for metal fabrication, repair, maintenance, and general workshop use with compatible drill chucks and equipment.
✓6 METRIC SIZES WITH STORAGE CASE: Includes 5mm, 6mm, 8mm, 9mm, 10mm, and 12mm drill bits in a reusable storage case for organized storage and transport. For harder metals, use an appropriate drilling speed, steady feed pressure, and cutting fluid when needed to help manage heat and extend tool life.
