Wave Ball Mill” for Roughing
WBMR Type
Features
Particularly suitable for die mold machining the WBMR replaceable
insert ball nose endmill efficiently roughs complex profiles.
Its high feed rate capability is a direct result of a sharp cutting edge
which is maintained during the cutting cycle by the special cemented
carbide substrate working in parallel with the ultra hard ZX coating.
Advantages l Wave shaped cutting edge
l Economical M class insert
l Precise clamping
l High feed rate capability
