Our Mission

We place a primary focus on quality assurance. At PROMAX Tools L.P. our quality management system concentrates on providing:

  • Defect free cutting tool products and services
  • Open communication with our customers in order to better understand their cutting tool product and service needs and expectations
  • State-of-the-art manufacturing, process control and inspection equipment
  • Employee training to maintain product quality

And most importantly, our goal is to satisfy customer requirements and expectations 100% of the time.

At PROMAX Tools LP, we specialize in high performance solid carbide end mills in both our PROMAX and DESIGN-RITE end mill lines.


  • Place a primary focus on quality assurance
  • Manufacture defect free cutting tool products and services
  • Employee training to maintain product quality

In order to obtain these goals we must strive to maintain the leading edge in manufacturing technology and processes. PROMAX Tools does this through the use of:

  • 40 CNC cutter-grinders, with support robotics, consisting of Walter-Grinder, Rollomatic, Anca, Excalibur and True-Tech.
  • Machine software that is constantly updated ensuring the most current technology is utilized.
  • Use of a central network tool program repository which ensures consistency between production lots.
  • Design and engineering departments that are invested in CAD-CAM technology, and most notably, Walter-Grinder and Rollomatic simulation software that assists in the off-line design prototyping and programming of new standard and "special" (make to print) solid carbide cutting tools.
  • Accurate measurement and quality control of precision cutting tools, including PROMAX Tools' advanced CNC Measuring Machines, Laser Micrometers, Optical Comparators and Video Microscopes to 400x power. This equipment provides our technicians and our inspection department to meet the customers' most stringent tolerances and other requirements on virtually any tool dimension.

In addition to the core precision cutting tool itself, we also take pride in the other elements that make PROMAX and DESIGN-RITE tools stand apart from the others:

  • In-House Surface Treatments and Coatings: Tool coating is preformed in-house at PROMAX Tools with two PVD (plasma vapor deposition) chambers. The onsite capability provides quick turnaround with coatings for both the PROMAX and DESIGN-RITE line of solid carbide cutting tools that come in Titanium CarboNitride (TiCN), Aluminum Titanium Nitride (AlTiN), Zirconium Nitride (ZrN) and our newest coating, nACRo®, an Aluminum-Chromium-Silicon nanocomposite that is ideal on Difficult to cut materials. (See more about our coatings by clicking here.)
  • Special Tooling Requests: PROMAX Tools has concentrated extensive company resources to guarantee a quick and flexible response to customer requests for special quotes, modifications and products. Quotes are normally provided within 24 hours, product turn around for modifications is just a couple days, while finished product turnaround for "specials", in most circumstances, is just 4 weeks. "Specials" are typically produced under the PROMAX name, while modifications can be under either product line. Communication with end users is always encouraged and tool engineering assistance is available.
  • Technical Support: PROMAX provides a toll-free number for technical support for all our product lines for both PROMAX and DESIGN-RITE. Distributors and end users are encouraged to call with any questions at 800-878-0502.

Customers who purchase PROMAX & DESIGN-RITE end mills receive both an excellent tool and the knowledge and assistance of the PROMAX Tools Technical Support and Customer Service teams. PROMAX Tools was built on the foundation that Customer Service is just as important as the product being sold, thus our customers receive the answers they seek and the information they need in a more than timely manner. As a PROMAX Tools L.P. customer, you can feel comfortable knowing that quality products and customer satisfaction are at the foreground of every decision we make.
