3Pcs 7/64 Inch Drill Bit - Industrial M35 Cobalt Titanium Aluminum Nitride, 135 Degree Split Point, 7/64" Diameter & 2-5/8" Total Length, 1-1/2" Working Length, for Hard Metals: Steel, Alloy

3Pcs 7/64 Inch Drill Bit - Industrial M35 Cobalt Titanium Aluminum Nitride, 135 Degree Split Point, 7/64" Diameter & 2-5/8" Total Length, 1-1/2" Working Length, for Hard Metals: Steel, Alloy

• Superior Hardness & Durability: Made from 5% cobalt HSS (M35 grade), heat-treated to HRC 72 for outstanding wear resistance and long service life
• Heat-Shield TiAlN Coating: Titanium aluminum nitride layer reflects heat away from the cutting edge, preventing tip burn-out and maintaining sharpness
• 135 Degree Split Point Technology: Self-centering design reduces walking and drilling pressure, allowing faster, cleaner holes in stainless steel and alloy metals
• Optimized Flute Geometry: 1-1/2" working length ensures smooth chip removal, reducing binding and breakage during deep hole drilling
• Versatile Metal Drilling: Perfect for automotive repairs, HVAC work, and drilling into hardened steel or cast iron components
• 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
