CoroMill® MH20 High feed milling Best-in-class high-feed pocketing Time to level up your high-feed milling operations with best-in-class CoroMill® MH20. This is a versatile tool with a large application area, but is primarily designed for pocketing applications in ISO S, M and P materials. 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 the catalog to page 1Robust cutter body The robust cutter body with increased strength assures a longer tool life and excellent stability at long overhangs. An open insert pocket design and a secure insert position ensure reliable machining with excellent chip evacuation and less vibration. A new cutter body material that provides higher fatigue and deformation resistance, assuring a longer cutter tool life. Internal coolant for optimal chip evacuation and high productivity in ISO S applications. Maximal diameter cylindrical shank that can be cut off to optimize stability at various desired overhang...
Open the catalog to page 2• High-feed concept suitable for many milling operations helps to reduce the number of tools, thus reduce the cycle time • Excellent stability at long overhangs with minimum vibrations thanks to a light-cutting action and a robust tool design • Optimized edge-line security for reliable corner machining and pocket milling makes unsupervised machining possible • Open insert pocket design for excellent chip evacuation • Light-cutting action ensures less power consumption and hence enables the use of smaller machines • Creates better surface finish with smaller cusps leaving less stock for the...

Open the catalog to page 7Sustainability with CoroMill® MH20 New cutter body material increasing the strength, and inserts with high edge-line security, assure a longer tool life and reliable machining with less scrap. In addition, with less vibrations and a more reliable concept design, the risk of tool breakage is reduced, making the operator’s and workplace environment safer. With a better surface finish achieved, 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...
