The Diamond Bead Reamer Set exclusively from EURO TOOL features three points and a 4-1/2 hollow handle in which to store them. You’ll find the Diamond Bead Reamer set to be versatile, easy to use and trouble free. Made in USA. Features include: Three diamond tips - small and large reaming tips plus 45° edge reamer. - Easy release chuck friction fitted into the aluminum housing which releases instantly when the collet is unscrewed. - Anodized aluminum handle; brass chuck so rust is never a problem.
How it works: 1) Loosen collet, insert the base of a point into the chuck and re-tighten. 2) Wet the point with water and turn it side to side until the hole is smooth or enlarged to desired size
