4 piece diamond coated bead reamer

This versatile 4 piece diamond coated bead reamer set enhances bead design possibilities by allowing enlarging and smoothing of small or rough holed beads.

Also use water as a lubricant to protect beads from cracking or chipping from the heat caused by the friction of using this tool.
