API Roller reamer is designed for various reaming operation but particularly for various reaming operation but particularly for stabilization purpose when drilling in very abrasive formations. It will fit hole sizes ranging from “6 to 28”. In addition, each body by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.

API Roller reamer Description:

1). Roller reamer is designed for various reaming operation. It can be used in hard formation or abrasive formation, in order to keep the standard hole size. When the bit size is under the standard size, it can ream the well bottom size to standard hole size. Whether drilling the vertical well or directional well, it can make the bit or casing come into the normal hole size. The features of roller reamer are small frictional resistance with well wall, strong abrasive resistance and long life.

 2). The body is made of modified alloy steel, fully heat treated to 285~341 Brinell hardeness and 54J minimum impact strength . Connections are phosphatized, coated with thread dope and equipped with thread protectors, and are accord with API standard. All types of cutters are also made of special alloy steel and full heat treated.

Roller type (T, F, and B) of cutters are offered:
Type T: Milled, machined with hardfaced sharp teeth for soft formations.
Type F: Milled, machined with hardfaced flat teeth, for medium hard formations.
Type B: Equipped with pressed-in tungsten carbide buttons, for hard formations.

API Roller reamer Benefits & Features

• Enhance reamer performance with cutters, bearing blocks and cutter pins that are made from molybdenum alloy steel, carburized and quenched to 58-62 Rockwell C. Cutter pins can be rotated 180 degrees for prolonged use.
• Achieve faster redress with easily changed cutters. Simply drive out one spring-pin and the cutter pin and replace them. A punch, drive bar and hammer are the only tools you’ll need.
