    Hi guys 0/

    I'm doing some small boxes 110 mm x 66 mm buy 30 mm deep, out of hard wood. I want to give it a nice round over as the boxes will be hand held. But I'm not sure what to use. I have a full router table and looked at the trend bits, the smallest I could find was :

    Dimensions:
    D=19 mm
    C=3/8 inch
    C=9.5 mm
    B=9.5 mm
    B2=12.7 mm
    R=1/8 inch
    R=3.2 mm
    Shank Diameter=8 mm

    I think 3.2 Radius might be to large, I'm really only trying to take of the sharp edges but I want it neat and sanding is a bit hit and miss.
    Any suggestions on a bit that could work, I don't need it to be self guiding I can set the fence up to guide along.

    Hi Fivetide
    Long time no hear.
    I got some small bearing guided roundover bits for doing the same job on Spilka spec windows i made for the house. Think i got them from Wealden tools.
    Regards

    If you can't find a smaller roundover maybe you could use a 45 degree cutter and adjust the fence so it was just skimming the arris.

    Or you could make your own 'scratch stock' from an old hacksaw blade

    Spelling mistakes are not intentional, I only seem to see them some time after I've posted

    Just use a portion of the edge of Ogee or Ovolo cutter like Roman ogee or bead ovolo or maybe some other formed tool. It won't give full round over but just breaks the sharp edge.

    You can get bearing guided 1/16" roundover bits.

    Most major manufacturers make them.

    OK, I am confused here, not difficult I know but.........

    What is the function of the bearing when used on a CNC machine?, surely it is not needed??, not like on a hand held router, or am I missing something here like I usually do??
