Threaded blade bits are divided into threaded cross bits and threaded X-type bits, which connect with threaded drill rods by threads to transfer impact power and rotation torque for breaking rocks. The threaded bladed bits, working with hydraulic drill rigs and hydraulic jumbos, have main threads of R25,R28,R3212,R38,T38,T45 and T51, which are widely used in open-pit mining, underground mining, tunneling, anchoring, furnace tapping, tunnel construction, hydropower projects, quarrying and construction.

Reaming bits are also known as pilot reaming bits, which are used for drilling central holes in tunneling. The reaming bits are divided in to an integral type and a split type. The split reaming bits are composed of pilot adapters and reaming bits.
