  • ✅ M35 COBALT DRILL SET: Yougfin M35 drill Bits have 5% cobalt, which gives them higher red hardness and wear resistance. Compared to HSS drills Bits, M35 drill bits for hardened steel are particularly suitable for drilling harder materials such as stainless steel and alloy steel, and are less likely to be damaged by overheating during machining.
  • ✅ 135° Split Point & Twist Design: The split point design increases the cutting edge on the tip, and the blunter 135° angle means more of the cutting edge touches the surface sooner. The grooves on the sides of the bits’ twisted shanks will bring metal shavings up and out of the hole as you drill.
  • ✅ TIPP:When drilling a hole with a cobalt drill bit, please add a little cooling lubricant oil on the metal to keep the cutting edge cooler. If possible you can place some wood underneath the steel . This helps cut cleanly through the material and not strike a surface below ,which might cause the cutting edge damage.
