With durable carbide tips and a shaft design that permits excellent control, these are outstanding turning tools. The shafts are machined flat on the underside to register squarely on the rest, so you can maintain a smooth cut by simply advancing or retracting the tool while moving it laterally, without the complex sweeping motion that ordinary round-shafted gouges require. When the tips begin to wear, you can simply loosen the locking screw and rotate the tip to present a fresh edge.
