13/64 Inch Cobalt Drill Bit Set, HSS M35, Industrial Grade, TiAlN Coated

13/64 Inch Cobalt Drill Bit Set, HSS M35, Industrial Grade, TiAlN Coated

• 13/64" Diameter for Specialized Applications: Often used for tapping holes or clearance in metal parts
• Superior Hardness & Durability: Manufactured from M35 cobalt HSS (5% cobalt), heat-treated to HRC 72 for long-lasting performance in hard metal applications
• TiAlN Coating for Thermal Protection: Keeps the cutting edge cool, preventing heat-related failure
• 135° Split Point for No-Walk Starts: Self-centering design reduces the need for a center punch, saving time and improving hole accuracy
• Compact Length for Control: 2-7/16" working length provides excellent rigidity, reducing bit wander in thicker materials like tool steel and alloy plates
• 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
