About Us

Our Story

Since 1963 Dun-Rite Tool and Machine Company has provided American-made premium tooling that meets or exceeds OEM standards to our customers. Our master machinists are true craftsmen that have the knowledge and experience to get the job Dun-Rite the first time! We can provide tooling for virtually any make and model of low RPM shredders or grinders. Our large inventory makes it possible for you to get the parts you need, when you need them. We have spent the last 53 years fine-tuning our manufacturing and proprietary heat treating processes to achieve the perfect balance of durability and quality, giving you the maximum wear life without sacrificing strength.

Custom Parts

Dun-Rite has total control over our manufacturing processes and quality. We offer precision tooling manufactured by master machinists on our state-of-the-art machining centers. Many customers have given us feedback that our tooling has higher quality and longevity than OEM tooling.


Our engineering team is dedicated to getting the job Dun-Rite the first time! Our team has over 53 years of industry knowledge that they use to create our finished products. Our engineers also have vast knowledge of the competitive landscape, and know what it takes to make our tooling outlast and outperform the competition.

Our engineering and manufacturing teams work together to make your project a reality. We offer custom solutions to meet your unique needs and we are willing to take on a challenge. We have seen many grinder manufacturers close their doors and leave their customers without a good source for tooling; Dun-Rite has been there consistently for those customers to get tooling equal to or better than OEM.

Manufacturing Process

From raw steel to finished product, Dun-Rite has total control. Our material comes in as raw steel, is brought to our modern machining centers for production, and we then complete a full inspection on each part. After inspection, parts that need to be hardened go through our proprietary heat-treating process. You can trust that our processes and our products are Dun-Rite every time!

OEM Quality and Precision

Our machining centers feature the best available technology to get you the exactness and precision you need, every time. We offer a full catalogue of tooling for single-shaft shredders and grinders. Our engineering team has also worked to provide enhancements to OEM tooling that improve strength and longevity. Many of our customers have given us the feedback that our tooling has higher quality and longevity than OEM tooling!
