Product Description

tungsten carbide button has superior wear resistance and impact toughness, and similar 
products with higher speed of drilling and digging.Series of ball tooth bit passivation 
using cycle is long, not to grind the life span of about the same diameter RenPian grinding
head drill bit 5-6 times of life, is beneficial to save auxiliary working hours, physical labor 
and reduce workers to speed up the project.
1.   promise the 100% virgin material .
2.   Sintere by vacuum sintering furnace and HIP machine with excellent specifications without any hole.
3.   suply blank and surface passivation.
4.  tungsten carbide button's high hardness of the cemented carbide and other characteristics are                       widely used in mining and quarrying and cutting process, also may be placed on a heavy excavators             used in bit.
5.  we can product the goods according your drawing and sizes.
6.  our new product grade's grain size can up to 6.0μm,highest wear-resisting and excellentest impact resistance.
