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 Taps 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.

Sherwood Ground Thread Tap Sets BSW Left Hand Straight Flute 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 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

BSF (Fine)

Swiss+Tech® HSS "Orange Ring" Taps

Manufactured to DIN 371/376.

Spiral Point - HSS-PM Nitride and Oxide Finish ISO Metric Coarse

For through holes. Taper lead to DIN form B (4.5 x P) Tapping Tolerance to 6HX 2BX.

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.

Dormer Machine Taps

MTT-X taps are manufactured from premium quality vanadium powder steel, branded HSS-XS1, for an unbeatable combination of toughness, edge strength and wear resistance. This winning combination enables them to withstand the stresses of threading in tough materials. Special gold finish with bright flutes/thread, or steam tempering (blue) guarantee a smooth cutting action with less build-up on the cutting edge.
