Thread button bits 64mm T38 for rock drilling 

This is the T38-64mm normal body thread button bit is made of international high-quality steel for drilling tools. They are processed by CNC lathe and heat treated in a vacuum furnace. The product performance has reached the international advanced level. Thread button drill bit can meet the requirements of rock formation with strong hardness, and can minimize the loss in the process of energy transmission. The fixed button force is uniform and not easy to drop and detached, so that the impact energy can be concentrated on the rock to achieve the purpose of efficient excavation. We can produce threaded button bit with R25, R32, T38, T45, T51, GT60 thread and diameter from 45mm, 51mm, 57mm, 64mm, 76mm, 89mm, 101mm, 115mm, 127mm and 152mm, use for hard formation drilling in mining, rock drilling, road construction, infrastructure construction, drifting, tunneling, bolting, and bench drilling.
