An orthopaedic cutting block includes a metallic bearing insert configured to support a bone cutting tool and a body moulded to the bearing insert. The bearing insert includes a plurality of chemically etched holes, and the body is moulded to the bearing insert such that each of the plurality of chemically etched holes is at least partially filled by a portion of the body. The body of the orthopaedic cutting block may include a bone-facing surface adapted to contact a portion of a patients bone, and the bearing insert may be positioned to allow a surgeon to perform a cut on the patients bone using the bearing insert for support.
