Frequently Asked Questions (FAQ)
For what materials is this drill bit suitable?
The HSS-R twist drill bit is ideal for alloyed and unalloyed steels, steel castings, sintered metals, non-ferrous metals, and plastics.
Is the drill bit also suitable for harder steels?
Yes, the HSS-R steel enables the drilling of materials up to approx. 900 N/mm².
How long does the drill bit last?
The service life depends on the correct application and the material being processed. The high quality of the HSS-R steel guarantees a long service life.
What does the reduced shank mean?
The reduced shank means that the diameter of the shank (10.0 mm) is smaller than the diameter of the drill bit (15.5 mm). This allows the drill bit to be used in drilling machines with smaller drill chucks.
How do I prevent the drill bit from wandering during pilot drilling?
A precise 118° tip angle enables easy pilot drilling without wandering. You should also use a punch to center the drill bit.
