ST68 102mm 127mm 152mm Regual Body Button Bit
With Flat Face and Drop Center Design
This type of bit is well known for its high wear resistance on medium-hard to hard abrasive rock formations (between 200 Mpa to 260 Mpa compressive strength).
Featuring spherical tungsten carbide inserts that is known to have strong configuration against carbide fracture. Used in benching and long hole drilling.
ST68 drill button rock bits are made of alloy steels and the best carbides with hot press technology.
