| 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.
Our standard material is a high quality grade of High Speed steel which
is vacuum hardened, and tempered at least 2 times to a hardness of
about 63 Rockwell C.
For severe knurling operations, such as rolling on 303 stainless or semi-hardened
steels, Accu Trak also offers knurls in a premium grade of high-cobalt
steel. These knurling tools are slightly harder and in most applications
deliver a substantial increase in tool life. Multiple coatings such as "TiN" and "Ferritic
Nitrocarburizing" are also available if necessary. Our sales representatives
will be happy to discuss any aspect of your knurling application and make
recommendations on maximizing tool life versus cost for any type of knurling
In addition to the many stock knurling dies shown above, we can manufacture
virtually any size and pitch special
knurling tools with 1-2 week normal delivery for standard knurl tooth
