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.

Spiral Point Tap Metric Fine Straight Flute Ground Thread HSS

A spiral point tap has a chiselled point that pushes the metal chips ahead of the forming threads. This is useful when tapping through-holes (holes that extend through the work piece).

Spiral Point taps are not recommended for use in blind holes: the accumulation of chips can bind and break the tap.

Plug Tap BSW (British Standard Whitworth) Straight Flute Ground Thread HSS

The Sherwood Plug tap is used last after the Taper and Second tap have been used, when threading blind holes it cuts threads to the bottom of the hole.

Sherwood Dies

Sherwood dies are for use in die stocks to cut external screw threads on metal rod, the split in the die allows the adjusting screws of the diestock to compress or expand the die to accommodate for slight variations in size of the material being threaded or die sharpness. Sherwood dies are available as Metric Fine, Metric Coarse, UNF, UNC, BA, BSF, BSW, BSPT, BSPF, NPT cutting threads all the dies are manufactured from HSS with precision ground threads to the applicable standard.

Tap Set BSPF (British Standard Pipe Fine) Straight Flute Ground Thread HSS

Each set of Sherwood taps contain one taper, second and plug lead tap:

Sherwood HSS Taper Taps are used to start cutting the thread. They are 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.

The Second Tap is used after the taper tap has cut threads into the hole as far as possible. It tapers back 3 or 4 threads before full thread diameter is reached.

The Plug Tap cuts threads to the bottom of a blind hole. It is only necessary to use the full set of taps when a blind hole is to be tapped.

Sherwood Dies

Sherwood HSS dies are used in diestocks to produce external screw threads.

Manufactured to: BS 1127.

Kennedy® Thredfloer Fluteless Taps

Form rather than cut the thread in almost any ductile material. These include aluminium, brass, copper, carbon steels, zinc and magnesium alloys and even some stainless steels. The material is "cold formed" into the relevant thread and has the advantage of being a full form thread unlike normal cut tapped holes. This make the thread stronger. The forming operation does not create chips so swarf contamination and blockage is illiminated and tap breakage reduced. Because there is no consideration for chip evacuation, Thredfloer taps can be run at higher cutting speeds and reduced cycle times. Lubrication grooves are a feature of all Thredfloer taps of M3.0 and over. These allow lubrication to reach the end of the tap to maintain tool life and to prevent damage from "Hydraulic Blow Out".

Guhring Standard Production Taps

Guhring standard production taps are marked with colour rings to help you quickly and confidently choose the correct tool for your job. Each ring relates to the unique machining behaviours of different materials as dictated by their type and condition. The role of material type and condition in selecting the proper tap for each application cannot be overstated.
Manufactured from HSS-E steel to DIN 371.
For through holes.
