Beskrivelse
Ø 3,1 x 49 x 18 mm. Short and highly stable multirange drill with outstanding heat resistance and special geometry for optimising chip formation and removal. – Short and highly stable multirange drill with outstanding heat resistance and special geometry for optimising chip formation and removal. Ideally suited for assembly work in thin-walled materials such as sheet steels, flat steel and profile steel comprising of medium and long-chipping materials.
HSS:
Heavy-duty high speed steel for drilling holes in easy-to-machine materials with a strength of up to 900 N/mm².
Shape C: Split point
Applications: for drills with very strong cores, for particularly tough, hard materials and for deep-hole drills.
Advantages: good centring, little pressure required. Chip spreading improves chip removal.
Disadvantages: perfect grinding only possible by machine.
TiN:
The titanium nitride coating is a universally usable standard coating. It has a 300-400 % longer service life than non-coated materials. Cooling is recommended.
