Solid Carbide End Mills Tooling by DIJET “One-Cut Ball 70” Ball Nose End Mill DH-OCHBTYPE ● 4 flutes solid carbide ball nose ● end mill for high hardened material up to 70HRC. ● From roughing to finishing. “DH COATING” Solid Carbide Ball Nose End Mill for high hardened material up to 70HRC High effiecient machining is possible due to 4 flutes. Unique flute geometry High rigidity of tool and un-equal pitch control the vibration. Adopting unique flute geometry at the center point achieved good Achieved low cutting force due to helix chip ejection & angle 45 and provided good cutting stable machining performance. Adopted new PVD coated grade “DH102” by combination of newly developed DH COATING & super micro-grain carbide suitable for high hardened material. Achieved longer tool life. ■ NEWLY DEVELOPED “DH COATING” DH COATING gives stable and high-performance machining on high hardened materials even with high speed dry condition, due to higher hardness and higher oxidation resistance than existing PVD coating.
