These sweep charts are close approximations of the various chisel and gouge sweeps. A lower sweep number indicates a flatter, less curved tool. The higher the number the more deeply curved the cutting edge.
Chisels and Skew Chisels (#1 and #2) have straight cutting edges.
Gouges (#3 through #10) have a curved cutting edge that is the arc of a circle.
Veiner Gouges (#11) have a deep, U shaped cutting edge.
V Tools are classified by the angle formed by the two wings of the V. Common V Tool angles are 45°, 60°, 75° and 100°.
Charts are not to scale. Sizes are in mm.
