GRAFF radius end four-flute milling cutter 4х55х11х6 mm with a spherical endface is used for machining radius grooves and rolling curved surfaces.
The radius milling cutters can be used for machining die molds and die blocks.
Milling cutters are made from steel M35 ( Р6М5К5 analogue), which belongs to the molybdenum group of high speed steel HSS. M35 steel has a high hardness at high temperatures due to the cobalt inclusion.
The radius end milling cutters are suitable for clean milling.
These milling cutters are analogues of the European DIN 844 classification.
