High-quality HSS ground twist drills

This 25-piece set contains fully ground High-Speed Steel (HSS) twist drills, designed for precision drilling in various metals. The drills are manufactured according to the DIN 338 standard, ensuring consistency and reliability.

Self-centering tip for accuracy

Each drill is equipped with a self-centering, split point at 135 degrees. This design provides active cutting action and perfect centering without wandering, making center punching or pre-drilling up to 10 mm unnecessary.

Wide range of diameters

The set offers an extensive selection of diameters from 1 mm to 13 mm, in 0.5 mm increments. This allows you to choose the right drill for every application, which is essential for precise and efficient metalworking.

Suitable for various materials

These HSS twist drills are suitable for drilling in:

• Alloyed and unalloyed steel
• Cast steel
• Cast iron
• Sintered iron
• Malleable cast iron
• Non-ferrous metals
• Hard plastics

Durable and efficient design

Thanks to the precision-ground cutting edges, these drills offer up to 40% higher drilling speed and up to 50% lower feed pressure than standard ground HSS drills with chisel edges. This results in faster and more efficient work with less effort.

Convenient storage case

The drills come in a sturdy plastic case, providing organized storage and easy access to the right size. This contributes to an organized workspace and increases productivity.

Compatibility with various drilling machines

The cylindrical shank of the drills is compatible with three-jaw drill chucks, making them suitable for use in drill stands and drill/drivers from various brands.
