The Fuse Bit is like having two bits in one. Use as a standard bit or use the ripple part of the bit to grind the edge of your glass pieces that have heavy texture to provide a smoother surface for easier copper foiling and burnishing. The Fuse Bit is ideal for shaping all types of glass, tile, stone and similar materials.

This bit is basically the more refined brother of the rather coarse and, frankly, uncivilized #7085 Inland WB-1R Ripple Bit (100 grit), for those of you keeping track of such things.

A ripple bit is used to shape the edge of glass that has a deep texture, such as ripple glass, so that you can easily foil or lead it. Your solder lines will be cleaner and you won't be so frustrated trying to get the foil on your glass. You can grind a single surface or the top and bottom simultaneously, and there is a section of diamond grit below the ripple part for regular grinding. This bit can also be used for stone or tile.

This fine grit diamond grinding bit is designed to grind a smooth, chip-free groove around the outside of jewels, cabochons, nuggets or whatever glass item you wish in order to wrap it with wire and incorporate it into jewelry or other creative and crafty item you might be making. It works with 20 gauge wire, which we sell in 500-foot spools. Also works with 22 gauge wire. (Watch this space for a future offering of a 1.4mm bit, which would work with 16 and 18 gauge wire.)

Fits any machine with a 5/16" motor shaft (Inland, Diamond Tech, Gryphon, etc.)
