Sollroc T60 Shank Adapters Rods And Bits Top Hammer Drill

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.
