13Pcs M35 Cobalt Drill Bits Set (1/16"-1/4")

⭐ Key Features

•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
