Universal 4 Flute Tungsten Steel End Mill Hard Alloy End Mill for CNC Machining

End Mill Features 1.Tungsten steel coated end mills can directly perform rough to finish machining on heat-treated materials with a hardness below HRC55, thereby improving machining efficiency on machine tools. 2.This milling cutter has strong versatility and is suitable for processing various materials such as alloy steel, stainless steel, copper, aluminum, and heat-treated steel. Its design and material ensure efficient cutting and good wear resistance, meeting the processing needs of different materials. Whether it is rough machining or precision machining, it can provide excellent machining performance and high precision machining quality. 3.The end mill is made from fine particle tungsten steel raw materials, providing higher wear resistance and strength.  It belongs to the category of high-hardness high-speed cutting end mills.  4.The spiral groove is ground as a whole to prevent chip sticking, significantly improving production efficiency.  5.By ensuring a sufficient chip space,
