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 UNC (Unified Coarse) 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.

Sherwood Reduced Shank Drills (Blacksmiths) - 1/2" Parallel Shank HSS

General-purpose drills for light duty work, for drilling steels, cast iron, nickel brass and graphite. Reduced parallel shank 1/2". Point angle 118, helix angle: normal, web thickness: standard, tolerance of diameter: h8, tolerance of shank: -0.01/0.08. Manufactured to BS328. Fracturing of the drill shank may occur if it is used for any other purpose or if extreme pressure is exerted on the drill.

For all dimensional specifications please refer to our catalogue.

Metric

All sizes will fit into a 13mm/1/2" chuck.

Sherwood Gauge Drills HSS Steam Tempered

General purpose drills for steels, cast steel, grey cast iron, malleable cast iron, nickel brass, aluminium alloy and graphite. Point angle: 118, helix angle: normal, web thickness: standard, relief angle: 8 - 20, tolerance of diameter: h8, tolerance of shank: f11. Manufactured to ANSI B328, BS 328 and DIN 338.

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.

Second Tap UNC (Unified 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.

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.
