    A D-Bit is what can take any form you can think up, originally it was the only way to Grind cutters for Engraving
    yes mactec, didn't know that they were called like this

    i have seen the clasical pantografs at work, when newspaper/typographic letter sets where stored on shelf those bits where runing at 10 20 - 100 k. rpms, inside little precision broches, with micrometric highet adjustement and low play paralelogram mechanisms

    arround here, they where not called d bits, but kind of pencil bits, so to say ... they where really sharp, just like a pencil, but not a regular pencil that you use a normal sharpner on it; no, some guys have had more sharp pencils, thus you could literally use as a white weapon really sharp ... imagine that the pencil tip was cut-off just like how you would do with a D bit, thus the pencil tip was sharpened asimetrical, at the end, on fine sand paper ... those could scratch your eye only looking at them

    back to engraving bits, some of them where really thin and long, thus they no longer had the clasical v shape, but more of an i shape long 10-12 mm

    building was build for this purpose, and floor was like in hospital; only place with higer accuracy was the state monetary

    in time, coins design got simpler ( less detailed, thus cheaper to produce ); also, many labels started to be manufactured on simpler routers, and laser engraving showed up; as a result, the place vanished in the end / kindly

    we are merely at the start of " Internet of Things / Industrial Revolution 4.0 " era : a mix of AI, plastics, human estrangement, powerful non-state actors ...

    Pantographs in general use D-Bits some use a Diamond drag just to scratch engrave

    People can call them whatever they like they are still D-Bits, a pencil point by itself won't cut anything, it would be able to scratch drag engrave
