Dormer has launched a new range of DIN standard multi-application taps offering improved thread quality, increased productivity and reduced cost per threaded hole.
Branded spectrum, they will be of interest to anyone performing threading operations in steel, alloy steel, stainless, cast iron, copper and aluminium. The new range complements Dormer’s existing ranges of ISO and ANSI standard multi-material taps.
Designed to promote a continuous production process, all spectrum taps feature a three radii flute profile with a constant rake angle that facilitates the creation of narrow, regular chips. This, combined with adequate flute space, results in negligible chip congestion.
Chip evacuation is further enhanced by the short thread length, which has the added benefit of reducing torque during threading.
Manufactured from premium quality vanadium powder steel for superior edge strength and wear resistance, an increase in tool life of between 30 and 70% is achievable with spectrum taps compared to standard DIN taps
Tommy Andersson, Dormer’s threading range specialist, adds “the optimum combination of geometry and material results in low wear and, as a result, further enhanced tool life.”
The spectrum taps are currently available in Metric thread form, in spiral point or spiral flute geometries with a choice of bright or steam tempered finish and either 6H or 6G tolerance. Metric Fine, UNC, UNF and G thread forms will be added to the range in September 2010.
The product launch is supported by a comprehensive brochure that includes full range details, dimensional data and optimum operating conditions. Further information is available by contacting your local Dormer office or by visiting the website www.dormertools.com
