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,R38,T38,T45,T51,ST58;
Reaming diameters: 76mm, 89mm, 102mm, 127mm;
These bits are designed for layer drilling, to enlarge pilot holes for long hole blasting of drop raises in underground mines, and constructing service holes.
reaming equipments come with three kinds: reamer bit match with pilot bit, or dome bit or hole opener bit separately.
