Reaming Bits for Rock Reaming

Reaming bits for Rock Reaming

Also called a pilot reamer, this tool works by first drilling a small guide (pilot) hole. It then automatically expands this hole to a larger, finished size.

High-quality reaming bits, reaming tools, reaming drilling bits, integral reaming bits, reaming bits with pilot adapter, button bits, and Threaded Drill Bits are all produced by Superdrill.

Button bit reaming was a common practice in mining and quarrying for blast hole drilling.
Drilling accuracy and direction can be guaranteed with the use of pilot adapters.
Bit type: Reaming bits / Dome bits

Angle of Connection: 6 / 10 / 12 degrees
