Screw tap colour ring system

With the screw tap colour ring system, users can find the right screw tap for their task quickly and reliably. Each
colour ring represents an ideal clamping geometry for the material to be processed. The colour system is based on
the ISO code for indexable inserts and therefore can be understood worldwide. Extremely universal tools do not
have a ring. The various geometries and their purposes are illustrated in the graphic below.

UNI MAX UNI UNI high-strength non-ferrous metals stainless steel cast and titanium and hard
up to 1000 N/ up to 1000 N/ above 1000 N/mm 2 short-chipping nickel alloy
mm 2 mm 2 non-ferrous
metals

each material has its specific characteristics and needs individual chip geometries. this means that the chip
angle, clearance angle and guide length must be set to achieve an optimal result. stainless steels and steels
need positive cutting to reliably penetrate the material and safely remove the chips. for processing very
hard materials, the cutter must be as stable as possible.
