Reaming Bit
Reaming 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. Our reaming button bits are mainly dome reaming bits and pilot reaming bits, such as R25 reaming bit, R28 reaming bit, reaming bit R32, R35 reaming bit, R38 reaming bit, T38 reaming bit, T45 reaming bit, T51 reaming bit, ST58 reaming bit, ST68 reaming bit, SR35 reaming bit...

Difference between Pilot Reaming Bit and Dome Reaming Bit
In top hammer drilling, dome reaming bits and pilot reaming bits serve specific functions in the drilling process. Here are the key differences in their functions and applications:
Pilot Reaming Bit:
Function: The pilot reaming bit in top hammer drilling is primarily designed to create the initial hole or pilot hole. It has a smaller cutting diameter compared to the dome reaming bit and is responsible for penetrating the rock and initiating the drilling process.
Application: Pilot reaming bits are used at the beginning of the drilling operation to establish a straight and accurately sized pilot hole. They play a crucial role in guiding the subsequent top hammer drilling toolsand maintaining hole alignment.
Dome Reaming Bit:
Function: Dome reaming bits in top hammer drilling have a larger cutting diameter and are employed after the pilot hole is established. Their main function is to enlarge the hole to the desired final diameter, removing additional rock material in the process.
Application: Dome reaming bits are used in the later stages of drilling to achieve the desired hole diameter. They contribute to the efficiency of the drilling process by widening the hole, allowing for the installation of larger equipment or casings.
In summary, the pilot reaming bit in top hammer drilling initiates the drilling process by creating a smaller pilot hole, while the dome reaming bit follows to enlarge the hole to the final desired diameter. This sequential use of different bits ensures precision, efficiency, and control in the drilling operation.
