    I can't say I can answer you with much experience, but I think you
    have identified a problem I have had. 

    Yes it will cut like butter but at the speeds they get, eg inverted
    cones will skip and make a mess if push the wrong way. I am not sure
    I need to adjust the techniques I have for my micromotor. I haven't
    tested it much. As far as carving billets. If I understand right, I
    played around with the burrs and coming in from an angle any rounded
    bur will accurately carve away what you like. It is very easy to
    keep steady and smooth. Not all the FG burrs work well on metal. 

    As far as micromotors are concerned I have a Ram and it is good. It
    is a bit old, but I was lent a new one and offered a very good price
    but I didn't buy it because it was not much better. That is, they
    are all about the same. Ram are very good to deal with and I
    recommend them. If you can use your drammel then it should be right
    for many basic tasks, and for the start you can spend the money on
    other things.
