Key Features
  • Professional M35 Cobalt Alloy – Made of 5% cobalt HSS with heat treatment, hardness up to HRC 67. Ideal for drilling stainless steel, cast iron, hardened metal, copper, and non-ferrous alloys
  • 135° pilot point prevents walking, reduced shank design improves concentricity for accurate holes
  • High Heat Tolerance – Cobalt allows continuous drilling at elevated temperatures; ideal for alloy steel plate up to 1/2" thick
  • Efficient Chip Removal – Tapered web helix design adds stability in tough materials. Large spiral flute quickly removes metal chips, enabling faster drilling speed
  • Ultrasonically welded outer shell creates a permanent seal; any opening attempt leaves irreversible traces, ensuring brand-new products. The inner storage case prevents metal-on-metal friction during transit, protecting cutting edges and coating, and serves as permanent organizer by size. This dual design combines tamper-evident security with a reusable case that lasts the drill bits' entire life
