GRAFF long four-flute end milling cutters 8х88х38х10 mm for metal with a cylindrical shank are mainly used to work with carbon and alloy steels (strength up to 800 N/mm2), nonferrous metals and stainless steel.
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 end milling cutters are suitable for clean milling.
Long milling cutters are used for deep milling.
These milling cutters are analogues of the European DIN 844 classification.
