Abstract: A laser beam is directed onto a bonding surface of a steel tool body to form a molten melt pool. Particles of high speed steel alloy are flowed into the melt pool and melt in the melt pool. The laser beam is moved along the bonding surface to form solid lines of high speed steel laser cladding metallurgically bonded to the cutter portion at the bonding surface and to each other. The cladding is abraded to form the cutting edge of a composite cutting tool.

Abstract: A cutting tool has a tool body and cutters metallurgically bonded to the tool body. The cutters are formed from laser to the tool body, with each cutter having a cutting edge formed thereon.

Abstract: An adjustable handle assembly includes a pedestal with an axial bore for mounting on a threaded shaft, a handle extending radially and upwardly away from the pedestal and a shaft release plunger radially removable in the pedestal. The shaft release plunger includes a threaded surface for selectively engaging and disengaging the shaft. Disengagement of the plunger allows rapid movement of the assembly along the shaft. The handle applies a torque to the pedestal when the plunger is engaging the shaft which allows the pedestal to exert a clamping force.

Abstract: A hand lever assembly including a plastic handle body molded around a metal insert for rotation of a rotary member such as an axle, spindle, or the like. The upper surface of the insert has a high point and a low point. The upper surface is further dived into arc surfaces, one extending clockwise from the low point to the high point and the other extending counterclockwise from the low point to the high point. The molded plastic body engages the sections of the insert upper surface. Torque applied to the handle body is transferred to the insert through the engaged arc sections of the upper surface.
