New ultimate deep face grooving toolProduct Video

Extremely rigid insert clamping and superior chip evacuation

Deep face grooving of up to 10 mm DAXN andup to 9 mm groove depth is possible- Effectively removes chips out of the cutting area and eliminates bird nesting- Extremely rigid insert clamping ensures tool stability during deep face grooving operations- Sharp cutting edge, combined with SH7025, the latest PVD grade, provides long tool life andsuperior surface quality12Superior chip evacuation

Internal coolant system

Effective chip redirector- Coolant is directed to the optimal
position close to the cutting tip,allowing excellent chip evacuation
during deep face grooving- Optimized geometry that effectively
redirects chips out of the groove and to
the side- Eliminates bird nesting of chips duringmachiningHigh clamping rigidity

FaceMiniCut eliminated bird nesting of chips
and chatter, which were the case with solid
carbide boring bars. As the result, 1.3 times
tool life increase was achieved.

FaceMiniCut eliminated bird nesting ofchips and allowed continuous machining
without stopping the machine for manual
chip removal. As the result, 5 times tool life
increase was achieved.
