Dormer tools
Dormer Tools’ latest product launch encompasses a range of taps designed to support a high level of performance in a range of hard to machine materials.
The material, coating and geometry of the new taps has been engineered specifically to facilitate a continuous production process in tough materials including, in particular, stainless steels.
The range, unveiled at February’s Southern Manufacturing event in Farnborough, coincides with both Dormer’s centenary and the centenary of Harry Brearley’s invention of stainless steel.
Simon Winstanley, marketing co-ordinator at Dormer Tools, said: “Stainless steel has been very much a part of Dormer’s history right from the very early days. It therefore seems fitting that the launch of these new taps comes in a year that marks not only the 100th anniversary of stainless steel but also Dormer’s own 100 years landmark.”
Manufactured from premium grade high speed cobalt steel with a choice of surface finishes, the taps offer improved wear resistance and low material adhesion.
The flute geometry allows adequate space for rapid and smooth chip evacuation, meaning negligible swarf congestion and, therefore, increased productivity.
The spiral flute taps feature a short thread length that generates less torque and further improves chip evacuation capabilities, meaning they can support higher cutting conditions than comparable equivalents.
The range includes spiral point and spiral flute geometries in a variety of thread forms with steam tempered or Super-B (TiAlN plus an additional edge treatment) coating.
