Marlco Litecut Keyway Push Broaches

Manufactured to BS4235;Part 1:1972 (normal fit Js9) and DIN6885 for Metric sizes, and BS46;Part 1:1958(1985) for Inch sizes. Precision made from high speed steel and simple to use with minimal set-up. The cutting geometry will suit most materials. Push broaches are designed for use in hand-operated or hydraulic mandrel presses, depending on load. Load per tooth, given in the tables, is based on a UTS of 400N/mm2 (approx. 25 tons/sq in). For other materials, adjust accordingly. It is important that broaches are reground when blunt and before damage occurs to the teeth. The use of cutting fluid is essential, and for steel, an oil with high pressure additives is recommended. Keyways from 2mm to 25mm width and bore diameters of 6mm to 95mm are possible. Both parallel and taper keyways can be cut by using the appropriate guide. Broach style L2 and L2M require the use of an extension shank which should be ordered separately. The shims specified for standard depth keyways can be adjusted to suit particular applications. Parallel broaches are listed and supplied as standard. Broaches for taper keyways are available to order.

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

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.

Plug Tap Metric 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.

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.
