Flat/Ball Nose 1/8 Inch, 1/4 Inch, 6mm, 8mm Tungsten Carbide End Mill For Iron Steel

The main features are as follows:
a. It can withstand high temperature, and can still maintain good cutting performance at about 800-1000 ℃. It can choose a cutting speed 4-8 times higher than high-speed steel when cutting.
b. High hardness at normal temperature and good wear resistance.
c. The bending strength is low, the impact toughness is poor, and the blade is not easy to sharpen.
Commonly used cemented carbide can generally be divided into three categories:
① Tungsten-cobalt cemented carbide (YG)
Commonly used grades YG3, YG6, YG8, where the numbers indicate the percentage of cobalt content, the more cobalt content, the better the toughness, the more resistant to impact and vibration, but will reduce the hardness and wear resistance. Therefore, the alloy is suitable for cutting cast iron and non-ferrous metals, and can also be used for cutting high-impact blanks and hardened steel and stainless steel parts.
② Titanium cobalt carbide (YT)
Commonly used grades are YT5, YT15, YT30, the number indicates the percentage of titanium carbide. After the carbide contains titanium carbide, it can increase the bonding temperature of the steel, reduce the friction coefficient, and slightly improve the hardness and wear resistance, but reduce the bending strength and toughness, and make the properties brittle. Therefore, the Alloys are suitable for cutting steel parts.
③ General hard alloy
Add appropriate amounts of rare metal carbides, such as tantalum carbide and niobium carbide, to the above two cemented carbides to refine their grains and improve their normal-temperature hardness and high-temperature hardness, wear resistance, bonding temperature and oxidation resistance , Can increase the toughness of the alloy, therefore, this kind of cemented carbide knife has better comprehensive cutting performance and versatility, its grades are: YW1, YW2 and YA6, etc., because its price is more expensive, mainly used for difficult Processing materials, such as high-strength steel, heat-resistant steel, stainless steel, etc.
