Abstract
A cutting tool includes a tool body having a first end engageable with a workpiece and a second end engageable with a spindle of a power tool. The tool body includes first, second, and third gullets opening through a first end of the tool body and being spaced asymmetrically around a circumference of the first end. The cutting tool also includes a blade extending outwardly from the first end of the tool body adjacent to the first gullet.
Claims26
A cutting tool comprising:
- a tool body having a first end engageable with a workpiece and a second end engageable with a spindle of a power tool, the tool body including first, second, and third gullets opening through the first end of the tool body and being spaced asymmetrically around a circumference of the first end;
- and
- a blade extending outwardly from the first end of the tool body adjacent to the first gullet,
- wherein the first gullet is oriented at an acute angle with respect to the second end of the tool body, and at least one of the second gullet and the third gullet is oriented at a generally perpendicular angle with respect to the second end of the tool body.

A cutting tool comprising:
- a tool body having a first end engageable with a workpiece and a second end engageable with a spindle of a power tool, the tool body including first, second, third, and fourth gullets opening through the first end of the tool body, the first gullet adjacent to and spaced a first distance from the second gullet, the second gullet adjacent to and spaced a second distance from the third gullet, the third gullet adjacent to and spaced the first distance from the fourth gullet, the fourth gullet adjacent to and spaced the second distance from the first gullet, the first distance being different from the second distance, the first and third gullets spaced about 180 degrees apart around a circumference of the first end, and the second and fourth gullets spaced about 180 degrees apart around the circumference of the first end, the tool body defining an axis extending between the first end and the second end, the first and third gullets being oriented at an acute angle relative to the axis, the second and fourth gullets extending generally parallel to the axis;
- a first blade extending outwardly from the first end of the tool body adjacent to the first gullet;
- and
- a second blade extending outwardly from the first end of the tool body adjacent to the third gullet,
- wherein a blade is not positioned adjacent to the second gullet and the fourth gullet.
