Hard rock 60-12T22 bullet teeth. 22mm low-cobalt tungsten carbide, powder metallurgical welding, balanced rotor.
| Blank Size | Main Alloy | Alloy Material | Alloy HRC Performance | Blank HRC Performance | Typical Strength Range |
| 30-60 | ∅ 22 | Tungsten-Cobalt Alloy | 69-70 | 42-45 | 10MPa-30MPa |
Suitable for sandstone, mudstone, and silicified limestone formations demanding high wear resistance on the pick body.
Low Cobalt Extra Coarse Grain TungstenCarbide Alloy
Diameter 22mm, and the large alloy body is designed for hard rock. lt uses innovative materialsto improve rock breaking ability and extend service life compared to traditional alloys.
Alloy Powder Metallurgical Welding
The pick head and carbide inserts employ alloy powder welding to achieve metallurgical bonding,Improves wear/heat resistance and provides better alloy protection.
High-Strength Tough Shank
The body is made by warm extrusion forging, integrating precision heat treatment technology with higher density and wear resistance, and anti-dropping retaining spring is standard in the factory.
Low Cobalt Extra Coarse GrainTungsten Carbide Beans
Made of wear-resistant raw materal, 12 hard alloy beans, strong impact resistance, protect the tooth body.
Dynamically Balanced Rotor
Five spiral grooves and five bosses onthe outer edge facilitate the rotation ofthe teeth and reduce eccentric wear ofthe tooth body.
