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.

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.

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.

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.

Iscar HELITURN Indexable Inserts

Iscar HELITURN LD Inserts with High Helical Cutting Edge for High Metal Removal Rates. The HELITURN LD inserts WNMX ...-HTW and CNMX ...-HTW are produced from the most advanced SUMO TEC grades. These inserts are designed with very positive radial helical cutting edges and positive rake angles ? a combination which substantially reduces the cutting forces and facilitates higher productivity.

The CNMX and WNMX insert corners are equipped with a wiper configuration which produces high surface finish, even at high feeds.

In many cases the surface finish is sufficient for eliminating a finishing cut.
HELITURN LD inserts were designed for heavy machining applications. Their unique design ensures reliable, Fast Metal Removal.

ISCAR has recently added the HMW chipformer for machining stainless steel, high temperture alloys and soft, low carbon steel.

CNMX and WNMX inserts require special tools with appropriate seats.

WNMX HELITURN Indexable Inserts

Grade Description: IC850 A tough substrate with a cobalt enriched layer combined with improved MTCVD TiCN and a thick alpha AI2O3 CVD coating. Recommended for general use machining of steel in a wide range of conditions, featuring high toughness and resistance to chipping and plastic deformation.

Sherwood 2 Flute Long Series Slot Drills Threaded Shank HSS

Used for milling keyways and slots in one unit. Bright Finish. Flute Type: 30° Helix. Manufactured to BS 122: Part 4: 1980.

Sandvik Coromant CoroDrill 880 Indexable Drilling Inserts

Guide to Geometry/Feed:
-GM geometry is the basic choice for most materials. Medium feed.
-LM geometry is the best choice for long chipping materials, e.g. low carbon steel and stainless steels. Medium feed, insert with sharp positive edge.
-GR geometry is the high feed choice for steel and cast iron. Insert with strong reinforced edge, suitable for roughing.
-GT geometry is a problem solver for unstable conditions and interrupted cuts. Low to high feed. Good chip control in most materials.
