The best cutting surface is achieved by developing the suitable cutting edge angle and corner radius for milling Copper Alloy, combining the smooth connecting end tooth, corner part and peripheral tooth.
37.5 ํ helix angle achieved high quality cutting surface.
・Strong helix angle improves shearing ability! Too strong helix angle might be causing bad effect on cutting surface and increasing cutting resistance.
37.5° is the best helix angle that achieved shearing ability and fine cutting surface！
