Burnishing Rolls for Knurling Dies
The majority of our product is knurling dies with teeth, but when a smooth surface is required, our engineers and tool makers have many years experience in the design and manufacturing of hardened rolls and dies for a variety of other applications. With multiple CNC lathes and state of the art vacuum furnaces we can guarantee great quality with the fastest delivery. Available in D2, M1, & Hi-Cobalt Steel, Accu Trak can do it all.
Accu Trak stocks 2 types of hardened rolls in various common sizes. The first type is used as a "Burnishing Roll" and has a hand-polished finish on the O.D. The other is most often used as a "Support Roll" and is unpolished. These are great tools for your burnishing and support roll applications. "Support Rolls" are 1/2 the price of "Burnishing Rolls".
Please call (800) 433-4933 or (508) 892-1787 for a quote on any type of hardened roll or die including anvil rolls, forming rolls, and burnishing rolls. Or click here to email us.

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 operation.
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 forms.
