KATDRILLS reaming drilling tools
Reaming drilling tools are deployed to enlarge the borehole diameter to the required size, following the completion of a pilot hole drilled to the target depth. Our product portfolio includes foru rock reaming tool variants: pilot reaming drilling tools, dome reaming button bits, adapter reaming button bits, and Conical Reamer Drill Bit.
Pilot reaming drilling tools adopt a split structure, integrating pilot adapters and reaming button bits as two separate components. By contrast, both dome reaming button bits and adapter reaming button bits(hole open bit) feature a one-piece design for enhanced structural stability.
