Groove Grinder Bit, Fine 2 pk

Aanraku brings you Twofers – superior quality, low-cost grinding bits. Use jewelry bits to grind a groove into the edges of jewelry for finishing and wire wrapping. The groove created in the edge of the cabochon fits 20 gauge wire for a secure wire wrapped finish. A huge time saver! Best of all, your jewelry pieces will be more durable.

Bits fit most glass grinders. Diamond mesh grit is 220 for fine grinding.

Color-change (from the nickle to brass) on the cylinder indicates that the fine diamond grit has worn away and needs to be replaced.

This package includes two bits and two hex wrenches.

Step-by-Step: Wire Wrapping Using a Jewelry Bit

1. Grind a groove around edges of glass cabochon with a jewelry bit.
2. Wrap wire around cabochon firmly from bottom, ending at top. Grip wire with pliers and twist to secure.
3. Bring wires up and wrap around a dowel 1/4″ away from cabochon.
4. Using wire nippers, trim ends around base to secure and tuck in ends.

Wash ground edges well, using a soft bristle brush to remove any residue that will show up after firing. Dry well before applying heat.
