Descriptions:
Mainly used in underground mining,rock drill buttons,oil cone drill
bits etc.
1. Made of special and excellent raw material,have more stable
properties.
2. Extra grain size available,have higher impact resistance and
lower hot crack and breakage.
3. Ground and tumbled,ensure uniformity of dimension and surface
smoothness,easy to mount.
4. HIP sintering,increase the strength substantially,therefore
extend service time.
5. Full range of grades and specifications available.
