Use Ultra Thread Zap to cut thread

Sometimes the hole in a bead or pearl is too small, is not straight, or the two holes in some hand-drilled beads may not quite meet. This simple diamond-tipped bead reamer is the perfect tool set to quickly solves all those problems. This four-piece set has all the shapes and widths you'll ever need. Steel tools encrusted with industrial-grade diamond are used to hand grind bead holes larger, and take out unwanted burrs from bead holes before stringing.
