TAISHAN Speed rod are made by hollow drill steels; We use advanced production technology CNC and hollow drill steel processing by Boring Method ensuring quality reliability , Optimize processing procedure, entirely automatic threading equipment to finish the thread naturally and reduce the concentration of stress. Shape once of whole heat-treatment ensures long lifespan , Usually for MF rods, there are R32, R38, T38, T45 ,T51,ST58, T60 threads, and different lengths of rods are available from 600mm to 6400mm usually.
1. Our raw material is 23CrNi3Mo, which is in same league as Sandvik Sandbar 64.
2. Advanced production process: produced by CNC machining and advanced heat treatment. It will connect the drill rod and the drill bit more better..
3. Friction welding workmanship :It makes the thread and the body integrated without broken.
4. Full-carburization drill rod for high wear-resistance and strength: Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
5. Complete types of drill rod for various drilling scenarios.
