4Flute flat end mill
product parameters : particle size 0.4um, HRC55, ALTIN coating, helix angle 35 °, 4Flute, suitable for 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 and high speed cutting tools, The flute covers ALTIN coating, which increases the tool's strength and abrasion resistance, prolongs the tool life, reduces the number of tool changes, and greatly improves the production efficiency,Mainly use plane cutting and side cutting.
