Tungsten Carbide Coal Button
Introduction
Tungsten carbide with excellent wear resistance and impact toughness, which with higher drilling speed than similar products. The long service life is 5-6 times of the grinding life of the same diameter blade head, which is beneficial to save auxiliary working hours, reduce manual labor and speed up engineering. The cemented carbide cutting coal miner and the boring machine picks, wherein the boring machine picks require higher hardness.
Application
Tungsten carbide coal buttons are mainly used in mining, tunnel construction, etc.
