SEC-WaveBall WBMR Type ■ General Features A 3D profiling ballnose endmill series capable of roughing die molds and machine parts that is available in sizes from ø20 to ø50mm. 3-D Rough Copy Milling ● WBMR Anti-Rotational Mechanism WBMR2000 Insert Shim Diagram （ø20 to ø50mm） ■ WBMR2000 Type / 2000L Type (ø20 to ø50mm) B ● Wave-shaped, high rake insert design that promotes a sharp cutting edge and low cutting force. A Circumferential movement of the （WBMR2250S） ● Economical M-class insert with strong cutting edge. C insert caused by cutting forces is ● Stopper guides prevent insert from slipping during machining. controlled by WBMR2000L guide faces A, ● Only one insert type required for large diameter cutters Insert Setting B and C , so （ø20 to ø50mm） as to allow stable cutting  (ø40 and ø50), easier tool management. （WBMR2500SL） ■ Performance ■ Application Examples ●Cutting Force ●Cold Molding Die  (SKD11) Flank wear after continous 4 Endmill Diameter ø25 WBMR cutting for seven hours was Competitor A Work Material: S50C less than competitor's Cutting Conditions product.
