1 TOO NEW Indexable Insert Ball Nose End Mill RM Update B020G eries Expansion For rogh and semi-finish milling of molds.

2 Ball-nose End Mill for Rogh to Medim Ctting RM2 Featres Ctting Edge Diameter Ø16, Ø20, Ø25, Ø30 Application High Rigidity arge insert thickness gards against fractre. Thick body core resists body web fractre. For roghing and semi-finishing of medim and large molds a Heel ct achieves high body rigidity and good chips control, avoiding damage and welding by chips to the body. Heel ct a treamlined pocket optimizes a balance of chips flow and body rigidity. ong and eries a In addition to the standard lengths, the RM series contains long neck and extra long neck types for long reach applications. Throgh coolant hole types are available with Ø16Ø32 as standard. Throgh Coolant Hole 90 ong

3 High Precision, Inserts trong Ctting Edge Inserts With strong geometry and togh edge condition for reliable rogh machining. Peripheral grinding improves the precision of the insert for longer tool life. harp, ow-resistance Inserts Top rake chip breaker type inserts for redced ctting forces. ower resistance reslts in higher qality srface fi nishes. Insert tolerance similar to G-class type at economical M-class prices. Inserts for Ø40 and Ø50 Uniqe design, 3-dimensional ctting edge:- Variable Radial Undlation (V.R.U. Pat. pending) for effi cient chip breaking to signifi cantly lower ctting resistance and vibration. crew, slot and key type insert location and clamping for extra secrity. NEW NEW INERT GRADE -MP6100, MP9100 With accmlated Al-Ti-Cr-N based PVD coating TOUGHΣ Technology A fsion of the separate coating technologies; PVD and mlti-layering realises extra toghness. Base layer High Al-(Al, Ti)N The new technology Al-(Al, Ti)N coating provides stabilisation of the high hardness phase and scceeds in dramatically improving wear, crater and welding resistance. P Graphical representation. Each grade has a layer sitable for each application area (Al,Cr)N Mlti-layering of the coating prevents any cracks penetrating throgh to the sbstrate.
