Stop burning up standard HSS bits on stainless steel. This set is made from M35 HSS with 5% Cobalt, giving it extreme heat resistance and the ability to cut through the hardest, most abrasive metals.

Technical Specifications & Improvements

• Material: M35 (5% Cobalt HSS) The 5% cobalt content provides superior “red hardness,” allowing the bits to maintain a sharp cutting edge at high temperatures. Ideal for drilling Stainless Steel, Cast Iron, Titanium, and other hardened alloys.

• Point Angle: 135° Split Point This is a critical performance feature. The “split point” design acts like a pilot hole, ensuring the bit starts cutting immediately on contact.

  • No “Walking”: Eliminates the need for a center punch.

  • Fast Penetration: Requires less feed pressure to cut.

  • Accurate Holes: Creates true, round holes right from the start.

• Quality Standard: Meets NAS 907B Manufactured to National Aerospace Standard 907B, ensuring industrial-grade quality and performance.
