Tungsten Carbide Drilling Button

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.

Product Introduction

The Carbide Inserts, Compacts Buttons for the Tricone bits, roller bits are usually be of very good thoughess and wear resistance, we make them from high quality virgin materials and sepcially treat them in the course of production.

Product Features

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.
