More features

• 15/64" Diameter for Precision Work: Often used for clearance holes and tapping
• Superior Hardness & Durability: Crafted from 5% cobalt HSS (M35 grade), heat-treated to HRC 72 for extreme edge strength and resistance to chipping
• High-Temp TiAlN Coating: Protects the cutting edge from thermal degradation, allowing consistent performance in stainless steel and alloy steels
• 135° Split Point for Precision: Self-centering tip provides exact hole placement, critical for engineering tolerances and alignment applications
• Short Flute for Rigidity: 2-5/8" working length minimizes bit flex, making it ideal for drilling accurate, straight holes in harder materials
• 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
