A roller reamer/stabilizer tool is shown with rolling cutter assemblies removeably retained within elongated pockets in the body of the tool by cap members capturing opposing ends of the cutter axle pin. The cap members are received in sockets adjacent opposed ends of the pockets and secured thereon by balls, received within a passage defined by the mating faces of the socket and caps, and by threaded bolts. A countersunk bore in the cap members receives the bolts therethrough and provides an entry into a transverse opening through the cap to the passage for inserting or removing the balls. A shim plate between the cap and the body determine the gauge diameter of the tool.
