The Milescraft PocketJig100 kit enables you to quickly connect your work pieces. Its small, compact design allows you to do applications where a small jig is required. Built-in board thickness locations for easy measurement and set-up of your work pieces, virtually eliminating the need for manual measurements. Everything you need to get started with your first pocket holes! This kit can be used on boards that are between 1/2" and 1-1/2" thick. The pocket jig features four built-in board thickness settings (1/2, 3/4, 1 and 1-1/2 [12, 19, 27, 38mm]) to allow you to accurately measure your board thickness. The built-in stop collar setting enables you to easily set your drilling depth, and the attached clamp magnet allows you to securely attach the jig to your work piece. The 3" face clamp is the perfect addition to this kit, but the magnet will attach to any standard metal clamp. The jig kit includes a 3/8" (9.5mm) PocketBit, 3/8" Stop Collar, 6" Magnetic T20 Star Driver, Hex Key, and instruction manual. This is a great kit for all your small project pocket hole needs!
