ABSTRACT:
A reamer for finish machining a bore formed in a workpiece and method for providing a reamer with an abrasion resistant material. The reamer includes a body defining an outer surface, a cutting blade and guide member each coupled to the body, and an abrasion resistant material coupled to the reamer to form a friction resistant layer having a contact surface thereon. The abrasion resistant material impregnates the reamer to define an intermediate layer of abrasion resistant material intermixed with the reamer. The method includes the steps of assembling the reamer, applying an abrasion resistant material to said reamer, and allowing the abrasion resistant material to impregnate the reamer to define an intermediate layer of abrasion resistant material intermixed with the reamer.
