EMUGE-FRANKEN USA Expands SELF-LOCK Threading Tools Line

EMUGE-FRANKEN USA has announced a significant expansion of its SELF-LOCK™ Threading Tools Line, adding new THREADS-ALL™ / AERO Thread Mills and broadening its line of High Ramp Precision Thread Gages. The company, based in West Boylston, Massachusetts, is a manufacturer of taps, thread mills, end mills, drills, gages, rotary tools, and precision workholding solutions.

The updated product line now includes fourteen new 2×D thread mill sizes ranging from #5-40 to 1"-12, as well as thirty newly introduced 3×D sizes from #2-56 to 1"-12, marking the first time the company has offered 3×D options within the SELF-LOCK series. EMUGE has also expanded its High Ramp Precision Thread Gages designed to inspect SELF-LOCK thread profiles.

The THREADS-ALL / AERO SELF-LOCK Thread Mills are engineered with helical flutes, multiple cutting teeth, and a TIALN-T46 coating. According to EMUGE, the tools are intended for demanding applications such as aerospace machining, where materials like titanium, nickel alloys, and stainless steel are common. The design allows three tooth pitches to rough and finish threads simultaneously, which the company states can extend tool life and reduce machining cycle times.

In a statement, Marlon Blandon, Thread Milling Product Manager at EMUGE-FRANKEN USA, noted that the SELF-LOCK design has been used in “thousands of safety-critical applications.” The internal thread profile is designed to create a repeatable self-locking screw connection, with an even stress distribution along the thread length to help prevent slippage in high-stress environments.

The broader SELF-LOCK product family also includes UNC and UNF cut taps, form taps, metric cut taps, metric form taps, and metric thread mills, along with a complete range of GO / NO-GO thread gages.
