I wish to cut 10mm diameter colored acrylic rods into 50mm lengths in quantity and polish the cut edges. These will be used in jewelry production so a finished look is necessary. A slight bevel would be nice. These could be chucked on a drill press then spun against an abrasive or buffing surface. For instance a sanding/buffing block fixed at an appropriate angle. Some guidance would be greatly appreciated.

you actually need to file only in one direction with a single cut file. Do not drag the file back across the filed surface. the file you are using only cuts on the push stroke, not pull.

This s avaleble
