Series T100 (MT4) - Inch

Sherwood 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.

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.

Sherwood® Knuckle Form Ripper Cutters

Sherwood® 'Rippal' 3 flute ripper cutters have centre cutting as standard and as they are manufactured from HSS-Co 8% they operate at higher speeds and feeds than conventional shank milling cutters, removing more metal per minute. The Sherwood® 'Rippal' cutter's unique geometry ensures a more efficient cutting action and reduced cutting time helps you to reduce costs and increase productivity. Power and workholding rigidity must be checked carefully before use as it is recommended that 'Rippal' cutters are used with consistent power feed rates to eliminate backlash.

Sherwood® 'Rippal' cutters are available polished or unpolished and with a weldon or combination shank.
