Dormer Machine Taps

Dormer machine tap ranges have been designed for use with a high quality floating tool holder. For synchronous tapping on CNC machines with a rigid tapping cycle, Dormer SynchroFlex tool holders are recommended for a precisely defined minimum compensation in order to maximise machine performance. This is particularly important for larger sizes of spiral flute taps.

Available in spiral point for through holes and spiral flute for blind holes with 45 spiral angle. The three radii profile, with a constant rake angle all along the flute, is specially designed to give an optimum performance and chip evacuation in materials being threaded.
Surface Treatment
Special gold finish with bright flutes/thread, or steam tempering (blue) guarantee a smooth cutting action with less build up on the cutting edge.

Manufactured from HSS-XS1 premium quality vanadium powder steel and HSCo for superior toughness and edge strength, to give a high resistance to wear and long tool life.

All taps are available in Metric thread form initially. Thread forms Metric Fine, UNC, UNF and G will be stocked from September 2010.
Short Thread Length
The short thread length means low torque and better chip evacuation.
Thread Depth
Threading to depths of up to 2.5 x Diameter.

Sherwood Taps

Sherwood HSS Taps are the general purpose option for thread cutting in most materials including steel, some stainless steels, cast irons and non-ferrous materials such as Aluminium, Brass and many others.

Manufactured with precision ground flutes for producing accurate thread forms, Sherwood Taps are available in all the popular thread forms and as straight Flute `Hand` Taps in 3 leads, Fluteless, Spiral Flute, or Spiral Point Machine Taps and also Long Series.

Sherwood Tap dimensions conform to ISO529 apart from NPT Forms which conform to ANSI 94.9. Straight Flute and Fluteless Taps are manufactured with a standard Bright Finish whereas the Machine Taps have an Oxidised Finish for best results dissipating the heat build-up associated with these applications.

Thread Forms are Class 2 medium fit tolerance.

For all technical and dimensional specifications please refer to our catalogue.

Taper Taps Metric Fine Straight Flute Ground Thread HSS

Sherwood taper taps are used to start cutting the thread is tapered back from the end 6 to 10 threads before a fully threaded diameter is reached this allows the tap to be positioned easily and correctly before it starts to cut the thread.
