About Tri Star Engineering, Inc.

Tri Star Engineering, Inc. has been manufacturing special cutting tools since 1976, and occupies a modern, 16,000 square foot facility in Elk Grove Village, Illinois. Tri-Star Engineering has a staff of more than 40 employees.

Tri-Star Engineering manufactures a variety of precision cutting tools. These include special drills, reamers, counterbores, trepan tools and hollow mills. We have the capacity to make these from solid carbide, solid high-speed steel, or with carbide tips. Industries served include the automotive, plumbing supply, aircraft, and appliance industries where the accuracy and durability of machine cutting tools are important. We are capable of manufacturing these cutting tools from your prints or our design created from your piece part prints.

Our range of specialized capabilities includes Radial and Axial CAM RELIEF grinding, in both internal and external forms. For more information and a detailed description of this process, visit our CAM Relief page.

Our CNC GRIND department has six of the special TRI-STAR CNC GRINDERS. These have the capacity to grind from solid material, both carbide and the super HSS materials, used in today's special cutting tools. This equipment is important to you as an end user because of the repeatability of process and reduced lead times possible.

We also offer increased support to you in several ways:

  1. We offer a repair service for our tools, re-sharpening them whenever possible, to "New-like" condition.
  2. We will continue to evaluate each tool we produce and make recommendations, if we have any, to reduce the costs to you & to suggest ways to make the tooling last longer.
  3. We will respond to your request for an expedited delivery in a timely manner. If you call in the morning, we can have an answer within 4 hours. If you call in the afternoon, you will receive an answer early the next morning.
    Tri-Star Engineering is a full service source for the design and manufacture of special cutting tools. We are dedicated to providing the highest quality precision cutting tools and customer satisfaction at a cost that proves to be a value, upon application. We thank you for this opportunity to introduce ourselves and look forward to doing business with you in the future.
