Slitting Saw Small Diameter HSS

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.

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.

Series J100 - Gauge Sizes

SwissTech Shank Milling Cutters

The latest enhancement of the SwissTech range, these cutters deliver excellent performance when cutting difficult materials, even at high speeds.

Manufactured from premium PM (Powder Metallurgy) tool steel, with an excellent cutting geometry. Designed for strength and rigidity, minimising vibration in high speed cutting applications and providing improved productivity.

These cutters are further enhanced by the SwissTech Peak Power coating, suiting dry cutting applications, having higher oxidization resistance and hot-hardness than conventional TiALN or TiCN coatings, withstanding the high thermal loads associated with high speed cutting applications.

Series 91 2 Flute Fine Slot Drill HSS-E PM Coated

Centre cutting.
Weldon shank to DIN 1835B.
Shank diameter to h6.
Dimensions to DIN 844.

Walton 3 & 4 Flute Tap Extractors

Thoroughly remove all chips of the broken tap. insert the extractor fingers into the flutes of the broken tap, pushing them gently but firmly into position. Push the holder down until it touches the broken tap. slide the sleeve down until it touches the work. Apply a tap wrench to the square end of the holder. Twist forward and backward a few times to loosen, then back out the broken tap.
