4 flutes high efficiency ball end mill EHHBE-TH3 Epoch High Hard Ball-TH3

Evolved by addopting a TH3 coating on 4-flute ball end mill for high hardened steel processing. On high-hardened steel processing, to achieve even longer tool life. Features of EHHBE-TH3 Highly efficient cutting with 4 flutes Special edge shape in tip area improves cutting performance. TH3 Coating provides long tool life even on hardened steels. Variable Pitch geometry enables vibrations to be suppressed even for 4 flutes. Wide chip pocket improves chip removal. Available for high-efficiency side milling. Applicable range Carbon steel Stainless steel Pre-hardened Hardened steel Hardened steel...
