Seco Tools Inc. continues to enhance its Multi-Directional Turning (MDT) program, most recently announcing the GS (Grooving Sharp) and GG (Grooving Ground) chipbreakers for grooving steel, nonferrous alloys and superalloys. The chipbreakers feature a positive rake angle of 10 degrees with a sharp edge of 10-micron honing. The GS geometry features a sharp edge without any protection chamfer and is mainly intended for nonferrous alloys. The GG (pictured) chipbreaker, which has a protection chamfer from 0.1mm to 0.2mm, is aimed at superalloys, but can also be applied in some steel applications. Both chipbreakers reduce cutting tool pressure to increase productivity and are to be used as "problem solvers" in applications where light cutting is more important than chipbreaking capability, according to the company. Seco's MDT is a flexible system that uses a single toolholder and insert for turning, profiling and grooving in both axial and radial directions. The toolholder features a clamping action that reportedly provides a rigid and stable contact surface.
