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...
