- 【12Pcs 1/4" Cobalt Drill Bits】TechHyren 12pcs set of 1/4" M35 high-speed steel cobalt twist drill bits meets your diverse drilling needs
- 【M35 Cobalt High Speed Steel】Made of industrial-grade M35 cobalt high-speed steel (5% cobalt content), its hardness (HRC65.5-68) and wear resistance far exceed those of ordinary high-speed steel. Even under the high temperatures generated by high-speed drilling, it can still maintain the hardness and toughness of the blade, effectively preventing edge curling and breakage, and extending the service life
- 【Application range】It is specially designed for stainless steel, alloy steel, cast steel and other hard metals, and can also be used for plastics, aluminum alloys and wood
- 【Fully Ground Process & 135° Split Point】The spiral grooves are fully ground, ensuring smooth and rapid chip removal, effectively reducing friction and heat buildup. The 135° self-centering tip design allows for precise positioning of the drill bit, eliminating the need for pre-punching to start drilling, improving efficiency and accuracy
