How do I adjust the Depth Collar on my Kreg Jig® K3 or K4 for different material thicknesses?

To get the right pocket-hole depth, you’ll have to adjust the position of the collar on the drill bit. Place your bit in the Depth Setting Gauge on the Kreg Jig® K3 or K4, with the step of the bit at the marking that matches your workpiece thickness. Slide the Depth Collar towards the jig base and lock it in place with the included Allen wrench.
