MM4500

Product catalog summary

Introduction
MM4500 is a new milling grade developed by Seco Tools for tough applications, particularly in unstable conditions such as long overhangs, interrupted cuts, or vibrations. It is optimized for duplex stainless steel but can machine a wide range of materials.

Specifications

Coating: CVD with 2 microns Ti(C,N) and 1.5 microns Al₂O₃
Substrate: Medium-sized grain WC+Co with 13%-wt binder phase content
Hardness: 1290 (HV10)
ISO Classification: M40

Test Results

Test 1: Material SS2377 1.446, tool life increased by 75% despite vibrations.
Test 2: Material Ti6Al4V, tool life increased by 250% under unstable conditions with long overhang.

Main Benefits

Reliable wear and longer tool life in unstable conditions.
Effective at cutting speeds lower than 150 m/min in Seco Material Group 8-11.
Performs well with or without coolant.
Suitable for difficult-to-machine materials like duplex stainless, Inconel, and Titanium alloys.

Application Area
MM4500 is ideal for applications where reliability is prioritized, especially when other grades like T350M, F40M, and P40 are not tough enough or wear by chipping.

WHEN RELIABILITY IS PRIORITISED NAIN BENEFITS MM4500 is developed specifically for applications requiring a very tough insert. 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. GRADE PROFILE Medium sized grain WC+Co When cutting data has to be reduced due to unstable conditions, MM4500 will give a reliable wear and a longer tool life.
