BA (British Association) HSS Ground Thread 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.

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

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.

Spiral Flute Tap UNC (Unified Coarse) Ground Flute HSS

Spiral flute taps are used for machine tapping of blind holes as the have a spiral flute that channels the swarf back behind the tap and out of the hole along the flute.

Sherwood Die Nuts

Sherwood ground thread die nuts are suitable for repairing damaged or crossed threads and clearing swarf from threads. When using a die nut (on an existing thread) it is not necessary to apply the same level of precise initial alignment required to form a new thread (i.e. with a die) as the nut will follow the existing threads. They are supplied as hexagon drive allowing them to be turned by a standard spanner or adjustable wrench without the need for a special stock.

Conform to: ISO 529

Second Tap Metric Coarse Straight Flute Ground Thread HSS

The Sherwood 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 a fully threaded diameter is reached. If threading a blind hole a Plug tap will be required to cut threads to the bottom of the hole.

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".
