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.

Allied Maxcut Thread Mills

The MaxThread™ threadmill range is manufactured from solid carbide with ground helical flutes and a TiAlN coating as standard. These product have been designed for the low volume/low cost production environment, providing excellent performance at a competitive price. A helical flute design has been maintained across the MaxThread™ range to allow
for maximum production benefits and to negate the need for straight flute thread mills. A comprehensive range of thread forms and technical information further supports the programme.

Features and Benefits:
Helical flute which offers increased strength and rigidity when cutting forces are applied.
TiAlN coated for increased tool life over uncoated tools.
Extensive range of thread forms.
High quality for consistent predictable production.
