4 Tips That Will Extend End Mill Life | Regal Cutting Tools
Deflection. Trying to cut too much material at too high a speed or feed rate can result in tool deflection, which is doubly taxing on end mills. First, deflection causes the mill to bend. Constant flexing and relaxing along the mill flutes weakens them, like worrying a paperclip. Second, when the mill bows while it is inside the cut, the flutes ...
