Dorian Tool International, Inc. Knurling Tools

Knurling has a wide variety of applications in day-to-day use. It is most commonly used for decorative purposes and for serration surfaces where components are locked or keyed together in unit assemblies. Knurling is obtained by displacement of the material when the knurl is pressed against the surface of a rotating work blank. A knurled tooth is “V” shaped. Knurling tools are used for producing straight, diagonal or diamond patterns, having teeth of uniform pitch on cylindrical surfaces. Forming Knurl forming is achieved by pushing the knurl wheels against the blank while rotating. This will cause the material to be displaced in cold form, reproducing the same wheel pattern on the blank circumference. The blank is increased accordingly to the Knurl Pitch. The force applied through forming is increased in larger diameters making knurling difficult and slow. Cutting Knurl cutting is achieved by using knurl wheels to actually cut instead of forming the blank. The knurl wheels are set at an angle, making the knurling edges of the knurl wheels cut into the blank. Pressure is minimized while speed and feed are increased.
