Cutting Tools
2
Design:
Ultra-fine grit solid carbide, type N, according to factory
standard, 30°,
Signum-coated,
with centre cut.
Cutting speed approx. 50% higher than with non-coated tools.
Dry machining possible.
These tools should only be used in shrink or hydro-.expansion
chucks.
Application:
Can be used for copy milling. The neck chip channel
makes optimum tool range possible and thus makes it suitable
for mould-making applications. Suitable for machining hardened
materials
up to 54 HRC
.
Note:
Copy milling, cutting values preferred at ap = 0.05 x d
1
and ae = 0.1 x d
1
