⭐ Key Features
•Extreme HRC 72 Hardness – 5% Cobalt M35: Constructed from premium M35 high-speed steel with 5% cobalt, fully heat-treated to HRC 72 – delivers unmatched edge retention and resists deformation under high torque
•THERMAL-BARRIER COATING: Titanium aluminum nitride layer protects the substrate from high cutting temperatures. Withstands temperatures up to 1000°C . Your bit stays sharper longer, even when drilling abrasive materials like cast iron
•M35 COBALT + 4241 HSS HYBRID: 5% cobalt cutting tip welded to 4241 high-speed steel shank, fully ground on automatic CNC equipment. The result: a bit that twists less and cuts more
•Anti-Slip 3-Flat Shank & 135° Split Point: 3-flat shank grips securely in any drill chuck; 135 degree split point enables immediate engagement without center punching – saves time and improves accuracy
•1" Diameter for Large Holes in Structural Metal: 1" size, 6" total length, 3" working length. Ideal for bridge construction, heavy equipment repair, and drilling through thick steel plates up to 1" thickness
•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
