Tools for drilling, other than for rock-drilling, with working part of diamond or agglomerated diamond

Interchangeable tools, for hand tools, whether or not power-operated, or for machine tools (for example for pressing, stamping, punching, tapping, threading, drilling, boring, broaching, milling, turning or screw driving), including dies for drawing or extruding metal, and rock-drilling or earth-boring tools

Assemblies, circuit boards or inserts specially designed for machine tools controlled in this annex: a.  Spindle assemblies, consisting of spindles and bearings as a minimal assembly, with radial (‘run-out’) or axial (‘camming’) axis motion in one revolution of the spindle less (better) than 0,0006  mm total indicator reading (TIR); b.  Single point diamond cutting tool inserts, having all of the following characteristics: 1.  Flawless and chip-free cutting edge when magnified 400 times in any direction; 2.  Cutting radius from 0,1  to 5 mm inclusive; and 3.  Cutting radius out-of-roundness less (better) than 0,002  mm TIR. c.  Specially designed printed circuit boards with mounted components capable of upgrading, according to the manufacturer’s specifications, ‘numerical control’ units, machine tools or feed-back devices to or above the levels specified in this Annex. Technical Note: This entry does not control measuring interferometer systems, without closed or open loop feedback, containing a laser to measure slide movement errors of machine-tools, dimensional inspection machines or similar equipment.
