Boost your productivity Overview Assortment Many components and machine tools require long tool assemblies to reach down in large components. Vibration risk is high and the remedy is either slow machining or damped tools. With Silent Tools, chatter and vibration are eliminated, the machining rate can be increased and process security improved. Benefits Productivity gains of at least 50% for the shortest adaptor lengths and up to 300% for longer adaptors Improved surface finish Improved process security Modular assemblies for required reach lengths Broad functionality range to cover all materials and applications Features Silent Tools unique damping mechanism Dynamically optimized, functionality over large rpm range up to 10 000 min-1 for short adaptors and 7000 min-1 for long adaptors Internal coolant through arbor Improved maximum temperature limitation, up to 100° C Possible to combine with all common machine tool interfaces Product areas Silent Tools™ CoroMill® 390 cutters Extra-long multi-operation end mills with integrated Silent Tools™ technology. All cutters have undersized shanks and useable lengths UL=6×DC. Cutter diameters (DC): 20, 25 and 32 mm Coarse pitch cutters with 390-11 inserts for full cut operations, and extra close pitch cutters with 390-07 inserts for high productivity in finishing Choose between two different machine tool interfaces: Coromant Capto® C5 or C6, or cylindrical shank A20, A25, A32.
