Abstract
A cutting tool for performing cutting of a relatively rotating external workpiece while relatively feeding the same in a specified direction is configured to have: cutting sections that have a tool edge, a base section, which is provided as one piece with or separate from the cutting sections and is for holding the cutting sections, a chip-guiding wall, which starts near a tool edge, is formed on the outer circumferential surface of the base section so as to extend in the direction moving away from the tool edge, and is for interfering with chips from the external workpiece and guiding the chips in a direction away from the tool edge. Provided thereby is a cutting tool capable of smoothly discharging chips during cutting.
Claims10
A cutting tool for performing cutting with respect to an external workpiece while relatively feeding the external workpiece in a predetermined direction, the external workpiece being shaft-supported to relatively rotate, the cutting tool comprising:
- a cutting section with a tool edge;
- a base section provided as one piece with or separate from the cutting section;
- a chip-guiding wall starting near the tool edge and being formed on an outer circumferential surface of the base section to extend in a direction away from the tool edge, the chip-guiding wall configured to interfere with a chip from the external workpiece and guide the chip in the direction away from the tool edge;
- and
- a discharge direction restricting face formed near the tool edge and configured to face a relative feeding direction of the external workpiece and the tool edge.
