This type of bit is used for making large cut holes in drifting and tunneling. Featuring spherical and ballistic tungsten carbide inserts that is known to have strong configuration against carbide fracture. Used in benching and long hole drilling.
Reaming rock bit applicable to reaming for first-grade and second-grade larger-diameter hole. It can reduce the sectional area between bit blade and rock hole, also solve the problem of large diameter's low drilling speed in the hard formation with good directive.
Reaming bits for quarry are designed to enlarge pilot holes for development rounds, long hole blasting of drop raises and constructing service holes. With Pilot adaptors, the drilling direction can be ensured and accurate.
