Guhring has expanded its thread-milling range with the introduction of the SC-TM-Z SP high-performance full-profile thread milling cutter. Designed to create a complete thread in just two revolutions, the new tool reduces cycle times while adding to one of the industry’s most comprehensive thread-milling portfolios.

According to Guhring UK national sales manager Chris Bush, the company now offers solutions ranging from micro and single-pitch thread mills to combination drill, chamfer and thread mills, providing manufacturers with options for virtually every threading application.

The SC-TM-Z SP is available in metric and metric fine sizes from M3 to M20. Its staggered-tooth, staggered-pitch design, combined with a patent-pending flute geometry, minimises radial forces and vibration, eliminating the need for a spring pass. The result is higher cutting speeds, improved dimensional accuracy and a more reliable machining process.

In performance trials, the cutter machined an M10 thread to 2.5xD in ST52 carbon steel 55% faster than a competing tool, while extending tool life by 17%, from 700 to 820 components. Guhring attributes this performance to the combination of its premium carbide substrate, Sirius coating and advanced cutting geometry.

Suitable for steels, stainless steels, cast irons, non-ferrous materials and heat-resistant alloys, the SC-TM-Z SP maintains true-to-gauge performance to thread depths of up to 2.5xD, delaying tool radius correction and extending process stability.

To support users, Guhring provides free access to its CNC Guhro ThreadMill programming generator, which produces programs for Siemens, Heidenhain, FANUC, Mazatrol and Hurco controls. The company also offers on-site technical support through a team of 20 field engineers across the UK and Ireland. More information www.guhring.co.uk
