01 Front angle
Negative front angle design
Adopt the suitable negative front angle design, and give consi
deration to the edge strength and sharpness. At the same time, the
large core diameter is used to enhance the tool rigidity and make
the cutting and chip removal stable.
02 Edge belt
Double edge belt design
Double-edge with 35 °helical angle design, making milling cutter
more wear-resistant, less product burrs and not easy to stick to
the Milling cutter.
03 Chip removal
Big discharge chip space
Large capacity chip discharge has strong cutting characteristics,
cutting timely discharge(draining), can achieve high efficiency
machining.
04 Passivated
Passivating deal with
The edge is passivated, magnifying 200 times without slight defect,
processing is not easy to have burrs, not easy to crack; the edge
is not passivated, the edge is easy to crack, collapse phenomenon.
the edge isn't flat.
05 Angle of chamfer
Chamfer easy to operate
Handle chamfering layout is easier to fit
