Stub Acme Internal SPTM Thread Mills
Internal Acme and Stub Acme thread mills will only cut the thread pitch size listed.
The same thread mill can cut both right and left-hand threads, and produce a variety of thread sizes (of the same pitch). Made of solid carbide for maximum tool rigidity. For single start threads only.
For other thread sizes, variations, and coatings, please call or email us for availability.
