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.

Sherwood Dies

Sherwood dies are for use in die stocks to cut external screw threads on metal rod, the split in the die allows the adjusting screws of the diestock to compress or expand the die to accommodate for slight variations in size of the material being threaded or die sharpness. Sherwood dies are available as Metric Fine, Metric Coarse, UNF, UNC, BA, BSF, BSW, BSPT, BSPF, NPT cutting threads all the dies are manufactured from HSS with precision ground threads to the applicable standard.

Guhring 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.

Series 205

Kennedy Hardness Testing Files

Set of 6 precision testing files with specially curved tips which are designed to reach into bores, slots and grooves, which cannot otherwise be tested with conventional types of hardness testers. Each file has a non-slip grip colour-coded handle for hardness assessment, with the Rockwell value printed on each. Files range from HRC 40 through HRC 65. Set comes complete with instructions and conversion chart Rockwell C to Vickers. Provides a quick and inexpensive way of testing workpiece hardness.
