The cutter body material offers higher fatigue and deformation resistance, ensuring a longer cutter tool life. Thanks to its light-cutting action, in combination with a robust shank design, CoroMill® MH20 ensures secure and vibration-free machining, even with long overhangs.

Open Insert Pocket

The open pocket design helps to improve chip evacuation and reduces re-cutting of chips. The design is optimized for chips generated by a high feed tool and minimizes smearing of chips, especially in ISO S applications.

Curved Insert Design

The single-sided two-edged positive insert has a strong curved edge with a reinforced corner radius, ensuring secure and reliable machining against shoulders and corners in pocketing.


Application Area


  • ​​High-feed concept suitable for many milling operations, helps to reduce the number of tools and therefore the cycle time.​
  • Internal coolant for optimal chip evacuation and high productivity in ISO S applications.
  • Optimized edge-line security for reliable corner machining and pocket milling enables unsupervised machining.
  • A sloped insert edge for gradual cutting engagement into the workpiece ensures a gradual chip load on the cutting zone and improves chip formation.
  • Creates a better surface finish with smaller cusps leaving less stock for the next operation.
  • Optimized geometries for high performance in ISO S, M and P materials.
  • Easy to handle

Sustainability with CoroMill​​® MH20

Ne​​w cutter body material to increase the strength, and inserts with high edge-line security, ensuring a longer tool life and reliable machining with less scrap. In addition, with less vibration and a more reliable concept design, the risk of tool breakage is reduced, making the operator’s and workplace environment safer.

Offering a better surface finish, the need for a semi-finishing tool is greatly reduced. This also means fewer tools in use, fewer stoppages and a quicker machining process with less inventory.

Not least, this light-cutting concept uses less machine power, resulting in reduced energy consumption and a lower noise level.
