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.

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 Spotting Drills HSS-E

These specially designed drills produce accurate and true positional hole starts for follow-up drills. They provide exceptional alignment accuracy, achieved due to short flute and overall lengths and no body clearance. This very short design allows chucking very close to the point so that they will produce a true start or center. Traditional twist drill bits may tend to wander when started on an unprepared surface. Once a bit wanders off-course it is difficult to bring it back on center. A spot drill bit will provide a far better starting point as it is short and has a reduced tendency to wander. For accurate and fast spotting on NC machines, jig drills and other capital-intensive boring machines. Also suitable for countersinking and chamfering of tapping holes in one operation.
90 point angle - Offers hole chamfering and spotting with one tool.
120 point angle - Specifically for spotting and closely matches a typical drill point. The cutting edges of the following drill will engage easily for perfect hole location.
