![]() ![]() I have found that for my use, a 3/8” mortise compression bit works best for pocket holes. Since I am working towards a goal of not drawing any rectangular cabinet components prior to cutting, this pocket hole cutting module will be a step towards that goal. You could also edit the parts file to a 3 axis move. There are also ways that you can “trick” the 2.5D design software to cut the tapered bottoms. After cutting a job using this method I decided to find a way to cut the tapered bottom pockets. You could add these to your cabinet drawing files as a 1.5” long vector or rectangle that you toolpath to the required depth. Many of the cabinet cutting and nesting software programs simply plunge the bit to cutting depth and move in the required direction, which results in a square, rather than tapered bottom. The typical screw pocket is 1.5” long, 10mm wide and a little over 10mm deep. We are looking to eliminate the time required for moving the material to the pocket cutter, plus that of the operator to cut the pockets by cutting the pockets on the ShopBot. This gives a fairly decent looking pocket with an angled bottom that helps align the screw properly. Commercial pocket machines use an angled drill bit that plunges laterally into the material face. Cutting the screw pockets on the ShopBot is a natural progression from cutting the panels and then moving them to a pocket machine. Occasionally when assembling our cabinets we need to install pocket hole screws for a blind screwed connection. ![]()
