Bull Endmill 4 Flutes Solid Carbide Corner Radius End Mills Radius HRC55
Bull endmill is a kind of corner radius end mill. This bull endmill is with single end. It’s mainly used for making a corner radius at the bottom.
The cutting edge of bull endmill is stronger than square end mills. So the bull endmill is with great productivity. It can be used in mold profiling applications with greater productivity than ball end mills. Our company’s solid carbide bull end mills are available in many diameters and over- lengths with different series for different applications.
