Accu Trak is Celebrating 38 Years of Quality Knurl Tool Manufacturing

About Accu TrakAccu Trak Tool Corp. was incorporated in 1985 in Worcester, Massachusetts (40 miles west of Boston). In 1990, we moved to a new larger facility in the nearby town of Leicester (Cherry Valley) , Massachusetts, set back into the woods at the top of a hill.

Accu Trak specializes in the manufacturing of standard and special knurling wheels and holders. We strive to produce a premium product made from high grade tool and high speed steels. We have our own vacuum heat treating furnaces and tempering ovens to insure our tools are hardened properly to last as long as is feasible. Most of our inch wheels have an ultra smooth LAPPED tooth profile for maximizing tool life and producing the smoothest knurling possible on the workpiece. A variety of coatings (such as TiN) or surface treatments (such as Ferritic Nitrocarburizing) can also be applied to any wheels we make to extend tool life further.

In the early 1990’s, Accu Trak introduced as standard, off the shelf items, our CONVEX/AXIAL FEEDING knurls. Our convex knurls, made of Hi-Cobalt steel with an "extended wear" treatment, have become the standard tool to use whenever the application requires the wheel to move axially to produce a wider/longer knurl pattern. Please refer to convex knurls for more information.

We believe we have available from stock the largest variety of both inch and metric sized knurling wheels and holders of any single location in the world. And what is not stocked, with our efficient production controls, we can manaufacture quicker than anyone else due to the large variety of ready made blanks we keep on hand and our huge inventory of a variety of tool steels. We also frequently make (and keep track of) literally thousands of over run special wheels from previous orders. When a custom made wheel with a standard tooth profile is required, our normal delivery is 1 - 2 weeks. Even faster deliveries are available with a rush premium.

We always have a knowledgeable technical person on hand between 8:00 AM - 5:00 PM EST to offer help with any of your knurling applications and to guide you to the optimum method of knurling your parts.
