The following table gives standardized diameter pitches and dimensional relationships when producing straight, diagonal, and diamond knurling on cylindrical surfaces having teeth of uniform pitch parallel to the cylinder axis or at a helix angle not exceeding 45 degrees with the work axis.

All data is in inch units

Diameter Pitch	160		128		96		64
Approx Depth of tooth or Increase in Knurled Dia.	0.009		0.012		0.016		0.024
