The Dosicol helps you evenly spread a predetermined amount of glue in biscuit joint holes — I’ve always seen this on the New Yankee Workshop and wondered where to get one. The Dosicol 177000 is made for #10 and #20 biscuits, and it comes with a base to hold the bottle in an inverted position for easy use.
The bottle’s wide mouth provides an easy path for the glue to flow through and makes the bottle easy to refill. If you’re doing a lot of biscuit work you might want to pick up this timesaver.
Made by Lamello, the Dosicol sells for about $45.
