Hi John,

       If you buy BIC pens, they have a 1 mm dia (0.0394") carbide ball 
already fitted in a nice cone shaped brass holder, the shank tube 2.2mm dia x 10.9 
mm long. You remove the plastic case and the ink tube and clean them with 
methylated spirits.

       I use 5 mm dia stainless steel bearings on a solid triangular tungsten 
carbide turning tool bit.

       Regards,

       Chris Chapman
