The Kreg Jig® K5 incorporates the best features of every Kreg Jig® that came before, with innovative upgrades you've never seen. The Kreg Jig® offers our simplest workpiece clamping system ever. The ratcheting clamp simply slides into place against your workpiece. Then, you lift the handle until you hear and feel two "clicks," and that's it. Now your clamp is set until you change to a different material thickness. Two large support wings can be attached quickly and easily to both sides of the K5 base. This way, long workpieces get solid support and won't tip. The Kreg Jig® K5 comes with a removable dust port that swivels from side to side so that you can position it exactly where you want it and then attach it to a standard vacuum house. This keeps your work area free of chips and debris, makes drilling easier and prolongs drill bit life by reducing heat.
