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.
