Our handy bead reamer set is an excellent tool for bead stringers. One diamond instrument is long and sharp for reaming bead holes. The other is a 45° point for rounding off the edges of holes so that they do not cut through bead cord. Both are set securely in hardwood handles. This will be a great addition to any toolbox. the separate components are also available individually. water should be used as a lubricant when using diamond coated instruments.
