MOLD FINISH MASTER Ballnose SUMIDIA Coated Ballnose Endmills Hard Brittle Radius SUMIBORON MOLD FINISH MASTER R SDCB Type Material r BNBR Type ● Enables high efficiency roughing and medium finishing of carbide molds. D Improved machining surface quality through use of wiper edge (available on ø1.0mm endmills and larger). ● Newly developed diamond coating offers long and stable tool life. Machined Surface Comparison ● Achieves the highest machining precision in combination Ra ：0.08μm Ra ：0.14μm with SUMIDIA binderless endmills. Roughness Rz ：0.62μm Roughness Rz ：1.04μm ● ø10-mm Hemisphere Milling With Wiper Edge Without Wiper Edge ● Combination of CBN SUMIBORON BNX20 with excellent wear resistance and optimal cutting edge design realises longer tool life.
