CoroMill® 745

Multi-edge face milling cutter for best production economy

Innovative design

​The patented insert positioning system provides the same light cutting action and performance as a positive single-sided milling cutter, but with a total of 14 cutting edges.

Cost-efficient solution

​The double-sided multi-edge design and the 42° entering angle make it a cost-efficient solution. It offers high productivity and a low cost per edge.

Reliable tool

​The secure tip seat and the large, robust insert with strong, light-cutting geometries are designed for reliable and predictable machining.

​Easy handling

The unique insert position is designed for easy and quick insert changes, and the large M7 screw makes clamping easy and exceptionally secure.

Differential MD pitch

Great problem-solving abilities when machining vibration-sensitive components and in weak set-ups with the unique differential MD pitch.


 

Save energy costs

The innovative design provides a light cutting action with excellent chip formation and low power consumption.
 

Less noise

The light cutting action generates a soft and smooth sound, creating a good working environment.

Differential MD pitch

The unique differential MD pitch is first choice in roughing operations where light cutting action is required, e.g. in vibration-sensitive and weak set-ups. It is a perfect problem-solver when vibration is a limitation in the production.

The length and weight of the cutter body has been reduced in order to boost the performance in low-productive applications. The cutter has a logarithmic differential pitch design, and the insert position is radially compensated to produce an even chip load on every insert.

The differential MD pitch is available up to diameter 160 mm (6.000 inch)
