E550 4 Flute KTC Tungsten Carbide General Processing End Mills

KTC Tungsten Carbide General Processing End Mills

End mills are made either out of cobalt steel alloys (known as high speed steel, or HSS), or from tungsten carbide in a cobalt lattice (colloquially shortened to "carbide"). The latter option is considerably harder, more rigid, and more resistant. Carbide tools can be run at speeds 2 to 2.5 times faster than HSS tools. When using carbide tools ensure that your machine tool is rigid with a solid spindle and that holders have little or no runout. Due to the brittle nature of carbide and the speeds at which carbide tools are typically run, rigidity is critical to prevent tool breakage.

Carbide cutters may be further coated with ceramics such as titanium aluminum nitride (TiAlN, aka AlTiN), titanium nitride (TiN), titanium carbon nitride (TiCN), and so on. Of these, the bluish-gray TiAlN coating is most common one, and by the virtue of reducing friction and improving hardness, it boosts the speed of metal cutting by up to 20%. It extends tool life.

Specifications:

E550 general processing milling cutter series adopt domestic high-quality fine grain tungsten steel material. Flexural strength: 3900mpa, grain size: 0.8μm, with coating (black / Bronze) by imported coating equipment. E550 milling cutters are with special angle design and strict quality control, which is especially suitable for ordinary medium and low carbon steel, alloy steel and other materials processing. With high precision quality control, and full inspection, all E550 series end mills are delivered with 100% qualification rate.
