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.

Accu Trak Knurling Tools are manufactured to extremely high standards from premium alloys. Many are available with a lapped tooth form to give longer life and impart a smooth, clean surface to the knurled part. Both sides and the bore of the knurl are finish ground to maintain close tolerance on diameter and side runout.

We manufacture both manual and CNC machines for benchtop or tabletop-size workspaces, along with a full line of accessories to support these machines. Our machines are small in size, but they are capable of making precision parts out of steel, aluminum, brass, or softer materials such as wood and plastic. All of our products are made in the USA.

All Diametral Pitch Knurls made to American Standards (ASA B5.30 1958). Diametral Pitch Knurls produce the D.P. number of teeth per inch of diameter. Rolled Circular Pitch Knurls, produce the TPI number of teeth per inch of circumference measured normal to the teeth.
