Product details

The cobalt spiral drill with a diameter of 3.3 mm is a high-precision metal drill specifically designed for machining steel and other metals. With a cylindrical shank and a point angle of 135 degrees, this drill offers excellent self-centering, supported by the cross-cut according to DIN 1412 C. The 5% cobalt alloy provides increased heat resistance and durability, making it ideal for use in demanding applications. The drill is precision-ground and meets industrial quality standards, making it particularly suitable for difficult-to-machine materials such as alloyed and unalloyed steel, stainless steel, and gray cast iron. Weighing only 11 grams, it is easy to handle and allows for precise drilling.

  • Right-hand cutting, Type N for precise drilling
  • Cobalt alloyed (5%) for increased heat resistance
  • Point angle of 135° for optimal self-centering
  • Suitable for difficult-to-machine materials such as alloyed steel and stainless steel
  • Precision-ground according to DIN 338 for industrial quality.
