13Pcs M35 Cobalt Drill Bits Set - TiAlN Coated, Fractional 1/16"-1/4"
- 13 FRACTIONAL SIZES – 1/16" TO 1/4" : 1/16, 5/64, 3/32, 7/64, 1/8, 9/64, 5/32, 11/64, 3/16, 13/64, 7/32, 15/64, and 1/4 inch. Ideal for pilot holes, dowel pins, rivets, screws, and precision metalworking tasks. Comes in a durable storage case (sold as set)
- SOLID ONE-PIECE CONSTRUCTION – NO WELDING Each bit is machined from a single bar of M35 high-speed steel. No welded shanks, no weak points to snap under torque. The round shank is fully ground for perfect concentricity and fits all standard drill chucks securely
- HRC 72 HARDNESS AFTER HEAT TREATMENT Made from M35 cobalt steel containing 5% cobalt and vacuum heat-treated to achieve Rockwell hardness HRC 72. This level of hardness allows the bits to drill through hardened steel, stainless steel, and cast iron without dulling prematurely
- TiAlN COATING PROTECTS AGAINST BURNING Withstands temperatures up to 1000°C The titanium aluminum nitride coating creates a ceramic-like thermal barrier that reduces heat buildup at the cutting edge. Drill faster and longer without the blue discoloration or edge softening that ruins standard bits
- 135° SPLIT POINT FOR INSTANT START Self-centering tip geometry eliminates walking on smooth metal surfaces. No center punch, no pilot hole required. Just place the tip where you want the hole and start drilling with confidence
- 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
