The Diamond Bead Reamer Set, exclusively from EURO TOOL, features three points and a 4-12" hollow handle in which to store them. You'll find the Diamond Bead Reamer set to be versatile, easier to use and trouble free. Made in the USA. The three diamond tips are small and large reaming tips and 45° edge reamer. This reamer features an easy release chuck friction fitted into the aluminum housing which releases instantly when the collet is unscrewed. It is made of anodized aluminum with a brass chuck so rust is never a problem.
