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 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 adapter reaming buttons bits are one-piece designed.
Alloy buttons are hot mounted into the drill bit, ensuring the bit good accuracy and durability.

Different types designed for different drilling scenarios and rock conditions.
High speed and drilling efficiency for professional operations.
Cost-effective, good performance with reasonable price.
