This bead reaming tool has a compact, light weight design.
It is perfect for softening rough edges of beads or for smoothing and enlarging bead holes.
Features a variable speed control from 1,000-18,000rpms.
Three diamond tips (#34.710-01 large reamer, #34.710-02 small reamer and a #34.710-03 cone reamer) are included.
Diamond tips have 3mm shanks.
The "handpiece" is approximately 6-3/8" (160mm) long and just under 1" in diameter.
The speed is adjusted by a thumb wheel on the back of the handpiece.
When loosening the collet for changing bits, you must depress a button to lock the driveshaft and prevent it from turning (do not do this while the unit is running).
