Horn thread whirling toolsHaving six or nine inserts, Horn claims its tools for thread whirling provide an efficient, cost-effective way to produce single- and multi-start external threads and profiles. With its base carriers and ring cassettes, the company says this new M271 modular tool system offers a number of combinations tailored to the various Swiss-type lathes and drive units on the market.

The S271 system allows customers to choose between conventional whirling with six or nine indexable inserts per ring cassette or the new Horn turbo whirling method, which uses nine precision-ground, double-edged indexable inserts. Three are for roughing, the remainder being finishing inserts, and all are tailored to the thread profile and material to be machined. Each cutting edge is subject to equal load, an additional factor in extending tool life.

A tool configurator, which is available on the company’s website helps with choosing the right combination of machine, drive unit and tool. The correct cutting data is also provided.
