The roller reamer is designed for various reaming operation but particularly for stabilization purposes when drilling in very abrasive formations. It will fit hole sizes ranging from 6"~28". In addition, each body by simple adjustment of blocks and proper selection of cutters, will suit a wide range of hole sizes.
Three different types (T, F and B) of cutters are offered.

Type F: milled, machined with hardfaced flat teeth, for medium hard formation.
Type B: equipped with press-in tungsten carbide buttons for hard and abrasive formation.
