By 1962 the Concentro Service Corp. of High Point, NC, was manufacturing a rather unusual-looking segmented spiral-knife planer cutter-head, the Kwik-Set. It used carbide cutting edges and was intended for heavy production use. By 1971 the company relocated to Greensboro. The cutter-heads were offered until at least 1979 but it seems to have disappeared after that time. It is possible that competition from the Newman Quietcut head, introduced in 1974, helped kill off the Concentro Kwik-Set head.
