MKJKIT KREG JIG MINI KIT | The Kreg Jig Mini is good for very specific applications where the smallest jig possible is required. The simplistic design includes the hardened-steel drill guide of the other jigs but does not include a reference fence, so material thickness adjustments must be made manually. This fenceless design allows you to make precise angle and stock depth adjustments as needed, making the Mini the most positionable Kreg Jig available.
