Dremel Bottle Cutting Jig

This is a jig for cutting glass bottles over the sink. I have been using this for about 2 years. I found this to be more reliable than the method of scoring the glass then using hot and cold water to crack the bottle. Running tap water onto the bit helps to keep down the glass dust.

Update 7/6/2019: Added a Dremel Flex Shaft adapter. This helps to keep the dremel from getting wet and gives more clearance for cutting short glasses out of tall bottles.

Requirements:
Dremel rotary too
