The rotary reamer is designed for every reaming operation but particularly for stabilization purposes when drilling in very abrasive formations. This is a versatile tool. They will fit hole sizes ranging from 5 7/8" to 26". In addition, each body of reamer can fit some holes (for example: the body of 6" reamer can fit the 5 7/8", 6", 6 1/8" holes) by simple adjustment of upper and lower seats.
