Thread Mills

Emuge, West Boylston, MA, has introduced advanced thread mills, featuring multiple teeth, a helical flute form, and multilayer TiAlN T46 coating. The new ZGF-S-Cut Thread Mills are designed to increase tool life over 10 times more than conventional tools and produce precise threads in exotic materials including titanium, stainless steel, and more. The first teeth act as a rougher and the next two teeth performing finishing. By dividing functions into three cutting edges, speeds and feeds can be increased, and threads can be produced in a single pass.
