Description
Version:
3-flute drill, specially developed for use at very high feed rates. Extremely suitable for machines with high power output and stable machining conditions.
The sector-leading technology of the chisel point guarantees optimum self-centring behaviour and permits spot drilling on irregular surfaces. 3 guide chamfers guarantee a stable exit from the hole and an exact roundness of the hole.
Note:
Flute length LC = L2 + 1.5 × DC.
HB and HE shanks are available at the same price as HA.
For HB shanks: use order No. 122436.
For HE shanks: use order No. 122435 + 129100HE.
Standard: DIN 6537 K
Tolerance nominal ?: h7
Number of cutting edges Z: 3
Tolerance nominal ?: h7
recommended maximum drilling depth L2: 41.3 mm
Overall length L: 107 mm
Shank ? Ds: 14 mm
Feed f in steel < 1100 N/mm2: 0.56 mm/rev.
3-flute drill, specially developed for use at very high feed rates. Extremely suitable for machines with high power output and stable machining conditions.
- Special point geometry with stable cutting edges and large clearance at the centre permits very high feed rates.
- The patented point geometry is optimised for chip flow and generates low cutting forces with good chip breakage.
- With 145° point angle for low burr formation when drilling through holes.
The sector-leading technology of the chisel point guarantees optimum self-centring behaviour and permits spot drilling on irregular surfaces. 3 guide chamfers guarantee a stable exit from the hole and an exact roundness of the hole.
