Reamer

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. It will fit hole sizes ranging from 4-5/8" to 26". In addition, each body, by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.

Its body is made of modified alloy steel, fully heat treated to 285-341 Brinell hardness and 54J minimum impact strength. Connections are cold rolled, phosphated, coated and equipped with protectors and are gagged to API Standards. Its body is inspected on an ultrasonic control unit over its full length and section. The original cutter and block assembly allows easy replacement of cutters by rig crews.
