Recommended Stroke Width - For single stroke characters, width of cut should be approximately 12% of letter height. Example: 1/2" letter height = .500" x 12% = .060. For standard cutters, the maximum stroke width of a 1/8" diameter cutter is .125, an 11/64" diameter cutter is .171, and a 1/4" diameter cutter is .250.
