⭐ Key Features
•5/16" Diameter for Mid-Size Holes: Commonly used for bolt holes and fasteners in metal assemblies
•Superior Hardness & Durability: Crafted from 5% cobalt HSS (M35 grade), heat-treated to HRC 72 for superior resistance to abrasion and heat
•Heat-Blocking TiAlN Coating: Reduces tip temperature by reflecting heat, preventing softening of the cutting edge and allowing continuous drilling in hardened steel
•135° Split Point for Hard Metals: Self-centering tip penetrates quickly without walking, even on rounded or uneven surfaces like cast iron
•Optimized Flute Length: 3-3/16" working length ensures efficient chip ejection, reducing binding when drilling deep holes in stainless steel
•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
