Ultra micro-grain quality carbide tools series (HSC)
6-12flutes, lengthen End Mill(straight edge, oblique edge)
◆.Solid ultra micro-grain diamond tungsten steel helical lengthened end mill
(6-12flutes, for high hardness application HRC40°~68°)
● Machining of high hardness material, excellent chip discharge, low noise, high efficiency
● With wide bottom-edge chip flute, it can machine inclined plane
● With many flute length, and soft overall length, it can make high speed machining
● With bottom edge facing center, it can regrind and cut up to top grade smooth With long and short bottom edge (with 2 flutes facing center), it can be applied in multi-purpose machining
● It can machine various sizes and specification and inclinationθ°, helical angles α°， Concentricity⊙≤0.005mm.
