A cutting tool piece is provided including a rear portion and a lead portion, the lead portion including a front section having an upper side angled downwardly and forwardly and a lower side angled upwardly and forwardly to form a transverse lead cutting edge. The rear portion includes a hole to secure the tool piece to a cutting tool and transverse cutting edges extending outwardly from side walls of the front section. Use of the tool piece prevents catching of the tool and excess vibration when it is secured to the end of the cutting tool and applied to a rotating wood block on a lathe. A system is also described for cutting a bowl from a wood block by coring out an interior portion of the wood block by applying the cutting tool which is curved and rotatably mounted to a post. Its lead end with the tool piece attached creates a circular groove about the lathe rotational axis in the wood. The cutting tool is advanced on a path which curves toward the central axis of the lathe. A curved support member of the same curvature as the cutting tool is rotatable about a support post and is positionable below the cutting tool. |
