ACCU TRAK Knurling Tools are manufactured to extremely high standards from premium alloys. Most of our stock knurls are furnished with a LAPPED tooth form to give longer life and impart a smooth, clean surface to the knurled part. Both sides and the bore 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 two times into 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 most listed items in a super premium grade of HI-COBALT steel. These tools are slightly harder and in most applications deliver a substantial increase in tool life. Our sales representatives will be happy to discuss any applications and recommendations on maximizing tool life versus cost for any type of knurling operation.

In addition to our large supply of stock items, we can manufacture virtually any size and pitch of SPECIAL KNURLING TOOLS including conical, convex, concave, and attachment style dies to fit various Thread Rolling Attachments and Machines. We are committed to a 1-2 week delivery for all specials having a standard tooth form.
