Thread Milling Cutters

BB Tool's solid carbide thread milling cutters produce internal and external threads with superior accuracy and surface finish. Unlike taps, thread mills work in both directions and can produce multiple thread sizes with a single tool.

Available for metric (ISO), UNC, UNF, and G (BSP) thread standards, with TiAlN coating for extended tool life in hardened steels and stainless steel.
