4Flute corner radius end mill
 Product parameters: particle size 0.4um, HRC55, ALTIN coating, helix angle 35 °, 4flute, Flute tip: with R angle. Applicable to copper, stainless steel, alloy steel, tool steel, carbon steel, cast iron etc.
Using Chunbao ultra-fine particles of tungsten carbide rod, with high bending resistance and abrasion resistance, grinding rods straight line beating control in 0.004. passivation treatment for  cutting edge,using for high hardness cutting tools, The flute covers ALTIN coating, which increases the strength and abrasion resistance of the tool, prolongs the tool life, reduces the number of tool changes, greatly improves the production efficiency, mainly use R angle cutting.
