Scandinavian Tool Systems is pitching thread milling as the lower-scrap route for difficult threads.
The company argues tapping remains fastest for standard through-holes in free-cutting steels and aluminum, while milling gives shops CAM-level diameter control, one cutter across multiple thread sizes, and lower breakage risk in gummy or hard alloys. Its solid-carbide and indexable tooling targets precision work, thin walls, blind holes, and large or special threads.
The tooling supplier offers solid-carbide and indexable thread mills aimed at precision and flexibility across materials.
Tapping wins cycle time on standard through-holes in forgiving materials, but thread milling lets shops set diameter in CAM, run multiple sizes from one cutter, and re-enter after a tool failure instead of scrapping the part. It excels in hard alloys like Inconel and titanium, and clears chips in blind holes.
The company positions the tools for shops that need to fine-tune class of fit without changing tools, cut scrap on expensive parts, and handle large or nonstandard threads more cost-effectively than tapping.
Frequently asked questions
In which scenarios is thread milling more advantageous than thread tapping?
Thread milling excels in blind holes, tough alloys, thin walls, large diameters, special pitches, and applications requiring tight fit control. It also reduces scrap risk and improves chip evacuation in challenging materials.
What are the primary benefits of thread milling over tapping for precision applications?
Thread milling allows for precise control over diameter, pitch diameter, and crest truncation through toolpath adjustments, making it easier to achieve tight classes of fit and micro-adjustments without changing tools. It also enables multiple light passes to improve surface finish in hard materials.
Can thread milling be used for both internal and external threads?
Yes, thread milling supports both internal and external threads, as well as a wide range of diameters, pitches, and standards, including metric and imperial.
