CoroMill® MH20 - 8

Sustainability 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...
