These unique bits eliminate chipping to the edge of your mirror and fine glasses. They are even recommended by Spectrum Glass for use with their new SilverCoats glass.
They are also the perfect choice for those times when you need a perfectly smooth chip free edge that won't be covered over by copper foil tape or lead came. Use for all your mosaic pieces, wind chimes, create decorative edging ...
Simply position the head so that your glass will pass through the grove in the bit. The profile of the bit will slightly taper the back and front side of your glass piece and the fine grit of the head will leave a soft frosted (and smooth) chip-free edge. You won't be disappointed!
