MM4500 is developed specifically for applications requiring a very
When conditions are unstable with long overhangs,
interrupted cut or vibrations, MM4500 is the grade to use.
Although it is optimised for duplex stainless steel,
MM4500 also has the necessary properties to machine a wide range
of materials in unstable cutting conditions.
When cutting data has to be reduced due to unstable
conditions, MM4500 will give a reliable wear and a longer tool
For unstable conditions – interrupted cuts, long overhang,
■ When reliability is the priority and smooth, consistent wear is
■ Cutting speeds generally lower than 150 m/min in Seco Material
Group 8 -11.
■ This grade is excellent at low to moderate temperatures and
MM4500 performs with or without coolant.
■ Problem solver in difficult to machine materials (duplex
stainless, Inconel, Titanium alloys etc.).
■ When T350M, F40M and other P40-grades are not tough enough; or
wear by chipping MM4500 can be used.
This clamping system eliminates insert movement even under
the most severe cutting conditions
Insert stability leads to more predictable tool life
Increased inset thickness reduces the chance of breakage
