1mm - 4mm Round Ball Nose Carbide End Mill Tungsten Steel Spiral Tools
Name: HRC50 ° 4 Flute hardened Tungsten steel Milling cutter
Spiral angle: 35 ° Coating: ALTin
Blade number: 4 Flute HRC: 50°
Applicable machine tools: CNC machining center, engraving machine, high-speed machine, etc.
Materials used: mould steel, tool steel, l, carbon steel, Thermal treatment quenching, etc
Main features: Germany Walter five-axis grinding machine, large core diameter design, chip removal smooth, enhance tool rigidity, easy angle; use fine grain grinding wheel processing, reduce surface grinding wheel trace, coating treatment more uniform, longer service life.
High hardness and wear resistance of tungsten steel base metal
Adopting new fine particle tungsten steel base metal, it has high wear resistance and strength, and belongs to milling cutter with high hardness and high speed cutting.
Champion quality long service life
The thermal treatment material below HRC50° can be processed directly by high speed rough process to fine process. The cutting face milling / short guillotine milling is the main way to reduce the frequency of tool change and to save the production time in advance.
Wide scope of processing saves processing cost
The milling cutter to imitate machining, semi-finishing,fine-machine recommended cutting materials within the HRC50°
