Supermini tools with CVD-D or PCD cutting edges are available in diameters from 1.5mm and with three different geometries to suit the application. H0 geometry with a rake angle of zero degrees is for machining hard, brittle materials such as carbides, pre-sintered ceramic materials, graphite and short-chipping brass.

H5 geometry with a rake angle of 5° is used to machine abrasive and soft materials, including aluminium alloys with a high silicon content, fibre-reinforced plastics and other plastics with abrasive content. The active HF chipbreaker geometry solves virtually all machining problems caused by uncontrolled, stringy swarf.
