The Kreg Jig Master System is the “fully loaded” version of the Kreg Joinery System, which helps you screw together butt joints. You drill and countersink your screw holes using the jig — then hold the pieces together with the clamping system as you join them with the screws.
The Kreg Jig Master System contains the standard three-hole drill guide, drill bit, and driver that most other systems have. It also includes a dust-collection shroud, a material stop for repetitive tasks, the Kreg clamp, and the benchtop base.
The Kreg Jig Master System sells for about $140.
