Sollroc Button Bits Shank Adapter

Sollroc Drilling Tools For R25,R28 And R32 Bit,Rods And Shank Adapter For Drifting And Tunneling Drilling Rods and Bits we provide the solution to optimized the performance and cost for difference rock conditions. For Drill Bits: *The Bits is made of quality steel and premium carbide grades *Process using CNC equipment ensure the accuracy and quality of each bit. *Provide difference designs to make the bit achieved the best rate of bit life and penetration rate to reduce the cost per meter For rods and shank adapters *Material are developed by cooperated with National &Local Joint Engineering Laboratory for High-performance Metal Structure Materials and Advanced Manufacturing Technology to improve the fatigue resistance of drilling steel. *Material is wiht strict process of steel smelting and rolling:Refining-Vacuum-Continuous casting- drilling hole method- surface peeling to control the content of non metallic inclusion and harmful element *Strictly control precision thread process to avoid thread too hot and broken effected by the high vibration and shaking of thread part when it works. *Heat treatment:Fully Carburization- Air cool quenching-tempering. It make the rod keep high toughness and improve surface harness adn whole strength as well *Thread strengthen: enhance the thread parts to improve the wear-resistance and longevity of the rod.
