Reaming bits were widely used in quarrying or mining for blast hole drilling, with pilot adaptors, the drilling direction can be ensured and accurate. Pilot holes are drilled depth and then reamed out to a larger diameter in a second pass required when hole diameter exceeds the capabilities of the rock drill and drilling tools available.


Materials: Tungsten carbide and high strength alloy steels. 
Processing: CNC milling and proprietary "hot (thermal) -insertion" processing procedure to insert the buttons as same as internationally well-known brand ,military grade requirements of heat-treatment guarantee durability


This type of bit is used for making large cut holes in drifting and tunneling. A smaller hole is first drilled and then reamed to the final size in combination with a pilot adapter. Large diameter service holes from level to level for drainage, electrical cable or pipe lines routinely used to ream cut holes for development rounds and for long hole blasting of drop raise
