Product Description

1/2" Diamond Core Bit for Glass and Tile



This is the most popular drill bit for stringing holiday lights in wine bottles and glass block.

I'm handy around the house. I built our deck, laid flooring and remodeled a bathroom. Many years ago, the first time I drilled a wine bottle, I put a huge star shaped crack in it. I did what I always did in that situation....ask dad. He knew what to do and showed me.

Our 5-page drilling guide is his advice, distilled into one simple set of instructions. The same advice applies to drilling wine bottles, glass block, ceramic tile and porcelain

Most of our customers have seen wine bottle lights and lighted glass block "Christmas presents". Now they want to make their own. Sound familiar?
