The Steel Force DJ184 Dual-Spindle Doweling Jointer produces super strong joints quickly and accurately every time. Simply line up the Dual-Spindle Doweling Joiner on a workpiece and in seconds you'll have two 8mm (5/16") holes drilled with 1-1/4" center-to-center spacing. If you want strong and accurate joints for your furniture, cabinetry, or construction this is the tool for you. When it comes to versatility, this tool has it with a plunging depth of up to 1-1/2" and angle adjustments from 0-90°. The fence uses a rack-and-pinion adjustment mechanism that allows for drilling at a height of 3/8"–1-1/16". Drilling height depends on your workpiece thickness. A clear plastic viewing screen over the drilling area supports accurate alignment during drilling operations and helps protect the operator from flying debris. This doweling joiner is equipped with a 1-1/4" dust port that can attach to a dust collection system or ship vacuum. Join shelves, frames, and many types of furniture quickly with minimal effort.
