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.

Guhring Machine Chucking Reamers Intermediate Diameter HSS-E

Available in diameters ranging from 2mm to 10mm in increments of 0.01mm. Made from HSS-E steel with a bright finish, left hand spiral flute. For all ferrous and non-ferrous metals and hard and soft plastics. For use on CNC machines, producing high quality reamed holes. Manufactured to DIN 212 and DIN 2172 section 1.

Shank diameter equals cutting diameter - 0.025mm.
dia 2.00 - dia 2.65 / dia 2.66 - dia 10.00 H9.

Diameter Tolerances (to H7)
Up to 5.5mm: plus 0.004mm minus 0.000mm
Above 5.5mm: plus 0.005mm minus 0.000mm.

Code numbers are determined by the nominal diameter. Delete the decimal point; create a four figure number by preceding the figures with a zero, if required. All codes finish with the letter A, i.e. 3.60 becomes 0360A.

For all technical specifications please refer to our catalogue.

Kennedy Holesaw Variable Pitch Bi-Metal HSS

Kennedy variable pitch bi-metal high speed holesaws feature a very aggressive cutting action, which gives a very smooth finish and substantial reductions in noise levels. Noise reduction is achieved by disrupting the harmonics produced when sawing certain materials and structures such as tubing and angle. An improvement in swarf clearance is also achieved.

Cutting depth: 28.5mm (1.1/8'').

Holesaw and Arbor sizes:
14-30mm - use Arbor K1 or K4.
32-210mm - use Arbor K2 or K10.

Sherwood Straight Shank Parallel Hand Reamers

Used to produce a close tolerance surface finish by hand in almost any environment i.e. on site or in a workshop. Manufactured to BS 328 : Part 4 : 1990 and DIN 206B.

Spiral Flute Parallel Hand Reamers - Metric

Kennedy® Stub Length Drills Carbide

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 DIN 6539.

Tolerances:
Cutting Dia. plus 0.000mm - 0.015mm.
Shank Dia. plus 0.000mm - 0.030mm.

Kennedy® Carbide Stub Length Drills - Metric

Sherwood® Taper Sheet & Tube Drills HSS

For producing clean holes in sheet metal and other thin-walled materials. Efficient cutting geometry, no pre-drilled pilot hole and the diameter of the finished hole is infinitely variable within the range of each drill, according to depth of feed.

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.

Tap Set BSW (British Standard Whitworth) 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.

Plug Tap BSF (British Standard Fine) 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.
