The K4 jig is a complete pocket-hole jig. For benchtop work, the drill-guide block installs in a base, or is removable for use as a simple portable jig. It has a hardened-steel insert that places holes 9/16", 7/8" or 1 7/16" apart, depending on stock width.
A pin registers in a series of holes, adjusting for material from 1/2" to 1 1/2" thick in 1/8" increments, and the base has a fast-acting toggle clamp and depth-collar setting guides.
A snap-in dust-collection shroud prevents drill flutes from packing with debris and overheating (1 1/4" dia. outlet requires an adapter, available separately, to link to standard 2 1/2" hose).
The body is made largely from rigid glass-filled nylon. Includes a 3/8" step-drill bit and depth collar, a hex key, a 6" #2 square-recess driver, a spacer for portable use, a starter pack of screws and plugs and instructions.
