KEIL Straight Shank Metal Drill Bit HSS DIN 338 Ground Split Point

HSS DIN 338 GROUND, SPLIT POINT
- Centre punching is not necessary
- Safe pilot hole drilling, even in slanting surfaces, in pipes and welds
- The feeding power is reduced by up to 50%
- The drill bit facilitates an increase in drilling progress by up to 45%
- Regular chip removal and reduction of chip friction
- Extremely true running and precise round holes
- No jamming of the main cutting edge and no slipping of the drill bit for through-holes
- High fracture strength and long life
- Reduced friction due to reduced external diameter in shank direction
- Higher breaking resistance due to conically reinforced drilling core
- Long operating time and fast drilling progress due to chemical thermal method of hardening and accurate cross-ground finish
