- achieves the best performance in almost
all materials and applications
- considerably less feed force required
- up to 60% longer service life
- up to 30% faster countersinking
- extremely quiet running
- optimal and smooth surface
- perfect chip removal
The ULTIMATECUT countersink is a high performance tool which stands for best performance:
up
to 30% time savings, twice as many countersinks as standard tools and excellent, smooth coun-
tersinking results in almost all materials.
The specially developed countersink from RUKO achieves this through its unique cutting edge
geometry, with the specially developed variably running relief grinding, transition radius and the
extra-wide chip flute.
