Single Profile Thread Mills (SPTM)
Why single profile?
SPTMs deliver reliable thread quality with a simpler, more flexible tooling strategy. They are often lower cost, more versatile, and able to cover multiple pitch sizes, while generating less side pressure.

Frequently Asked Questions
Q: What is a Single Profile Thread Mill (SPTM)?
A: An SPTM is a thread mill that forms one thread profile at a time, which makes it a flexible option for producing a variety of thread sizes and pitches without needing a dedicated multi-form tool for every thread.
Q: Why choose an SPTM instead of a tap or multi-form thread mill?
A: Shops choose SPTMs because they’re often less expensive, more versatile, and can cover a range of pitch sizes while generating less side-cutting pressure, which helps a lot on deep threads.
Q: How can one SPTM cut a range of pitch sizes?
A: Because the tool is single profile, you can program different thread pitches via the toolpath (helical interpolation) within the tool’s intended range, reducing the number of thread mills you need to stock.
Q: Are SPTMs better for deep threads?
A: Often, yes. SPTMs tend to create less side-cutting pressure, which helps keep the cut stable as depth increases (less tool deflection, less “push-off,” and more consistent results).
Q: Will SPTMs help reduce tooling cost and tool crib complexity?
A: That’s one of the biggest advantages. When an SPTM can cover multiple pitches/sizes, you can reduce tool count, simplify inventory, and avoid buying dedicated tools for every single thread callout.
Q: What thread forms do you offer in SPTMs?
A: We offer SPTMs in UN, Metric, UNJ, ACME, and Stub ACME, so you can keep the same versatile approach across common thread standards.
Q: When should I not use an SPTM?
A: If you’re running very high volume on one exact thread and want maximum throughput, a dedicated solution (like a multi-form tool) may be faster. We’ll help you choose based on cycle time goals, material, and required thread quality.
