Benefits of the Parabolic Flute Form
Heavy web construction increases rigidity under torsional load thus eliminating chatter at the cutting edgeswhich cause edge break down and early failure. The Parabolic drill web is 50-90% thicker than the standarddrill, depending on drill diameter.
Wider flute form, together with quicker spiral, promotes better chip removal while allowing easier coolant flowto the drill point.

HOW TO ORDER SPECIALS
MODIFIED STANDARDS
There are many instances when a special tool (a tool not found in the Somta catalogue or price list) can bemanfactured from a standard product. We call this a ‘modified standard’. Somta has both the capabilityand capacity to offer this service which, under normal circumstances, means a short delivery time.
The following are typical drill modifications:
Intermediate DiametersStandard sizes can be ground down to special diameters and tolerances.
Reduced Overall LengthsStandard drills can be cut to special lengths.
Drill PointsThe standard drill point angle is 118° included. This can be modified to any angle required. Many special
Drill Terminology
points are available which include web thinning, notch points, split points, double angle points, spur andbrad points etc.
Tangs and FlatsTangs can be produced to DIN, ASA and ISO, also special whistle notch flats on shanks.
Step DrillsStandard drills can be modified into step drills.
Surface TreatmentsA full range of surface treatments including nitriding, stream oxide, chemical blackening, gold oxide andvarious titanium coatings are available.
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 the stepangle.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 correctly designeddrill and these are often used in mass production engineering.
Some of the hole types that can be drilled in a single operation.
