Thread Mills

*Photos may not be the exact representation of products.

Thread mills are extremely versatile tools that allow for the cutting of various diameter threads at the same pitch, as well as creating both left- and right-handed threads without having to change tools. As an alternative to tapping, thread milling can produce the threads that you need to complete a variety of projects, from low to high production applications.

RedLine thread injector thread mills are very price competitive and perform extremely well in many applications and materials. All RedLine carbide thread mills are proudly made in the USA with only the finest materials. Our thread mills are ground to create both internal and external thread forms using the same tool, as well as cut imperial, metric, NPT, and NPTF thread forms with ease. Our broad range of products includes: standard, side and end coolant through thread mills, as well as our exclusive extended reach thread mills.  All of our thread mills are AlTiN coated to extend tool life and increase cutting speeds.
