KAT DRILLING
1 / 5
Reaming drilling tools are used when a large diameter is needed to be reamed out after a pilot hole is drilled to a depth. We provide 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 adapter reaming buttons bits are one-piece designed.
Applications: Drilling works for blasting duties in tunneling, construction, mining, quarrying, etc.
