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 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
