Reaming drilling tools are used when a large diameter is needed to be reamed out after a pilot holes is drilled to a depth. We manufacture pilot reaming drilling tools, domed reaming button bits and adapter reaming button bits.

Pilot reaming drilling tools consist of pilot adapters and reaming button bits, however, both domed reaming button bits and and adapter reaming button bits are one-piece designed;

Thread sizes:R25, R28, R32;
Reaming diameters: 76mm, 89mm, 102mm, 127mm

High Grade Tungsten Carbide Reaming Drill Bit R32 12 Degree

Description

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.
