Precision Manufacturing. Proven Results.

For over 30 years, we’ve supported the aerospace and metalworking industries with both standard and custom carbide cutting tools and tool holders, delivering exceptional quality at competitive prices.

Our CAD-based design and blueprinting services make it easy for customers to develop precise tooling solutions, from custom inserts to complex holder designs. Whether you’re machining a prototype or high-volume production parts, we help you do it with confidence.

When tools wear down, break, or need adjustment, we also offer expert repair services — restoring them to original specifications to extend tool life and reduce downtime.
