Number & Letter Gauge Drills:
Gauge drills are still in common use in the U.S. In the past, they were popular elsewhere, but now have been largely discarded in favour of metric sizes. When using a gauge rather than a standard measurement of size the user has to refer to a table of gauge sizes. For example, to drill a hole which is 10 thou (thousandth of an inch .0010) bigger than a 1/8 inch bolt, the user must first work out that 1/8 inch is 125 thou, so the hole size needed is 135 thou, and then must look up in a reference book which gauge drill bit is closest to this diameter - a number 29. Number gauge sizes are similar or equivalent in some respects to, but different from, American wire gauge. Number gauge is usually used from size 80 (the smallest) to size 1 (the largest) followed by letter gauge size A (the smallest) to size Z (the largest). Number gauge is actually defined down to size 97, but these smaller sizes are rarely encountered. It happens that as the technology for making small drill bits and drilling small holes has become more available, metric drills have become the norm.

BSF (British Standard Fine) 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 Jobber Drills Steam Tempered HSS

Suitable for drilling steel, cast steel, alloyed and unalloyed, grey cast iron, spheroidal iron, sintered powder metal, German silver and graphite. Manufactured to BS328/DIN338RN.

Black Finish (W-Finish)
This is the most common surface finish and is the result of a steam tempering operation in which steam is passed over the product during a controlled tempering cycle, producing a black oxide layer. Black tools are generally recommended for ferrous applications where the oxide layer aids chip flow, helps to dissipate heat by retaining some coolant on the tool surface and also helps to prevent the tool from staining.

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.

Plug Tap UNC (Unified Coarse) 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® Solid Carbide Drills

Sherwood Solid Carbide Stub Drills are suitable for drilling into steel, cast steel, cast iron, chilled cast iron, malleable cast iron, non-ferrous materials and abrasive plastic.
Point angle: 118°, helix angle: 30°, tolerance of diameter: h7, tolerance of shank: h6.
Manufactured to Works Standard.

Tap Set UNF (Unified 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.
