About this product

HRC 72 Hardness – M35 with 5% Cobalt: Made from M35 high-speed steel containing 5% cobalt, fully heat-treated to HRC 72 – delivers outstanding edge retention and resistance to deformation in hard metals PROVEN COBALT FORMULA: M35 with 5% cobalt content, welded to 4241 HSS and fully ground. Hard enough for stainless and spring steels, tough enough for everyday shop use TIAlN THERMAL PROTECTION: Coating reduces cutting temperatures and prevents edge breakdown. Withstands temperatures up to 1000°C. Drill longer without stopping to cool the bit SMOOTH FLUTE FINISH: Fully ground and polished flutes evacuate chips cleanly. Less friction means less heat and longer tool life 135° Split Point & 3-Flat Shank: Self-centering split point eliminates the need for center punching; 3-flat shank prevents slipping in the chuck, ensuring full torque transfer The drill bits use a dual-layer design for security and durability. The outer clamshell is ultrasonically welded, making tampering evident and ensuring factory-fresh arrival. Inside, a custom storage box prevents metal-on-metal contact, protecting bit edges and coatings. The box also serves as a permanent organizer, keeping bits separated by size. This system guarantees product integrity at purchase and offers a reusable storage solution for the bits' lifetime
