Product Description

Thread Dome Reaming Bit Top hammer Rock Drilling Tools Mining Drill Bit
Reaming bit, also known as pilot reamer bit, is a hole opener that drills a pilot hole to a certain depth and then reams the hole to a larger diameter.  It is mainly used for center hole reaming in long hole drilling.  Threaded reaming bits are divided into integral reaming bit (dome type, pilot type) and split-type reaming bit.
Reaming bits were widely used in quarrying or mining for blast hole drilling, with pilot adaptors, the drilling direction can be ensured and accurate.  Pilot holes are drilled depth and then reamed out to a larger diameter in a second pass required when hole diameter exceeds the capabilities of the  rock drill and drilling tools available.
