⭐ Key Features
•HRC 72 Hardness – M35 with 5% Cobalt: Made from M35 high-speed steel containing 5% cobalt, fully heat-treated to achieve HRC 72 – provides superior wear resistance and maintains a sharp cutting edge through repeated use
•COBALT-RICH CUTTING EDGE: M35 metallurgy with 5% cobalt content, fully ground on automatic machines. Harder than standard HSS, so it powers through alloy steels without dulling
•TIAlN COATING = COOLER RUNNING: Reduces coefficient of friction and shields the base metal from heat. Prevents blue-burning and edge breakdown during extended drilling cycles
•PRECISION GROWN FLUTES: Fully polished flutes eject chips faster and reduce binding. Cleaner holes, less effort, and better surface finish on exits
•135° Split Point & 3-Flat Shank: Self-centering split point eliminates walking; 3-flat shank prevents spin-out even under high torque – compatible with drill presses, hand drills, and magnetic drills
•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
