Bead reamers are useful for widening and de-burring the holes in
beads. This set includes two different reamers set in hardwood handles. One
reamer tapers from 3mm to 0.3mm and is diamond coated. The other reamer has a
45 degree point for rounding off the edges of holes so that they do not cut
through bead cord. Use water or diamond lubricant for smoother cuts and longer
life. Overall length averages 5” (12.5 cm).
