Somta Tools was founded in 1954 by Samuel Osborn Ltd of Sheffield, England, through its subsidiaries Osborn Steels and Osborn Mushet Tools. The name Somta was chosen as the acronym for these companies operating in South Africa.
Somta continues to operate from its original site on Moses Mabhida (formerly Edendale) Road in Pietermaritzburg. Somta's expansion has been brought about by the acquisition of two cutting tool companies during the 1980's. Additional growth is realised by continual investment in new plant, with emphasis on state of the art CNC equipment such as Junker, Normac, Rollomatic, Walter, Reinecker and Reishauer machines including new ANCA and Walter CNC grinding machines to further expand solid carbide range manufacturing capacity.
From humble beginnings in 1954 with 20 employees, Somta has grown into one of the largest cutting tool manufacturers in the southern hemisphere, operating from offices and modern manufacturing facilities laid out over 3 hectares with a complement of over 400 employees.
The factory in Pietermaritzburg manufactures 7 000 standard items and a further 3 000 made-to-order items to serve local markets and export markets in over 70 countries worldwide.
Somta Tools specialises in the design and manufacture of standard and custom tools for the industrial and "do it yourself" markets. Product categories can be summarised as drills, cutters, reamers , threading tools and toolbits, which are made in a wide range of sizes, using various materials (HSS and Solid Carbide) and Balzers PVD surface coatings to extend wear life.
The company's vision of "To manufacture and supply superior cutting tools, driven by a culture of service excellence, to global and domestic markets" is supported by ISO 9002 which was achieved in 1991 and ISO 9001 in 2003 and 2008.

Benefits of the Parabolic Flute Form
Heavy web construction increases rigidity under torsional load thus eliminating chatterat the cutting edges which cause edge break down and early failure. The Parabolic drillweb is 50-90% thicker than the standard drill, depending on drill diameter.
Wider flute form, together with quicker spiral, promotes better chip removal while allowingeasier coolant flow to the drill point.

Specify whether drill is to be Step or Subland Type.D = Diameter of large, fluted section.P = Diameter of small, fluted section.A = Shank Diameter.L = Overall Length.F = Flute Length.E = Length of Small Diameter. This is measured from the extreme point to the bottom corner of thestep angle.X°= Included angle of the step angle.S = Shank Length.
It is possible to drill two or more diameters in a hole on one operation with a correctlydesigned drill and these are often used in mass production engineering.

MODIFIED STANDARDS
There are many instances when a special tool (a tool not found in the Somta catalogue or price list)can be manfactured from a standard product. We call this a ‘modified standard’. Somta has both thecapability and capacity to offer this service which, under normal circumstances, means a shortdelivery time.
The following are typical drill modifications:
Intermediate Diameters
Standard sizes can be ground down to special diameters and tolerances.
Reduced Overall Lengths
Standard drills can be cut to special lengths.
Drill Points
The standard drill point angle is 118° included. This can be modified to any angle required. Manyspecial points are available which include web thinning, notch points, split points, double anglepoints, spur and brad points etc.
Tangs and Flats
Tangs can be produced to DIN, ASA and ISO, also special whistle notch flats on shanks.
Step Drills
Standard drills can be modified into step drills. (See drawing on page 64).
Surface Treatments
A full range of surface treatments including nitriding, stream oxide, chemicalblackening, gold oxide and various titanium coatings are available.
