Product details

The Cobalt Spiral Drill Bit from kwb is a highly advanced tool specifically designed for machining metal and steel. With a diameter of 6.5 mm and a precision-ground blade, this drill bit offers excellent performance and durability. Made from HSS steel and alloyed with 5% cobalt, it provides extreme heat resistance. This makes it particularly suitable for difficult-to-machine materials such as alloyed and unalloyed steel, stainless steel, gray cast iron, and plastics. The cylindrical shank allows for easy handling and compatibility with common drilling machines. The 135° point angle and cross grind according to DIN 1412 C ensure a self-centering function that guarantees precise drill holes. This drill bit is an essential tool for professional applications and demanding projects.

  • Cobalt-alloyed HSS steel construction for increased heat resistance

  • Self-centering cross grind according to DIN 1412 C
  • Suitable for a variety of materials, including alloyed and unalloyed steel
