Guhring has expanded its hole-making and threading range with the arrival of the MTMH3-Z. An expansion of the Drifter series of thread mills, the new MTMH3-Z Drifter helical-drilling thread mill demonstrates high performance levels when processing materials up to 66 HRc.

Combining core drilling and threading in a single operation, the MTMH3-Z Drifter helical-drilling thread mill offers process reliability when wet- or dry-cutting all material types. With two oil grooves on the shaft to provide optimum cooling with cutting fluid or air, the range also has a left-hand cutting geometry that stabilises performance during climb milling. A fine-grained carbide composition characterised by its high hardness complements this geometry and makes the tool suitable for hard machining.

Guhring’s temperature-resistant TiSiN coating prolongs tool life and performance. Furthermore, the MTMH3-Z Drifter incorporates a special face geometry with hollow grinding that makes process-safe core-hole drilling and thread milling possible in almost all material types.

With a shank diameter from 3 to 12 mm and a neck relief from 5 to 40 mm, the new thread milling series is suitable for creating threads from M2 to M16 on a material range that includes all steels and stainless steel, cast and graphite iron, aluminium, and titanium alloys. Suitable for drilling and threading holes up to 2.5xD in a single operation, the MTMH3-Z Drifter can reduce set-ups, cycle times, tool inventory and costs.

CNC Guhro thread-mill software enables users to specify the thread data by selecting from all current thread standards and then inputting the material requiring machining. At this stage, the software provides the optimal parameters.
