Kreg Jig K4 Master System

The Kreg Jig K4 Master System combines the Kreg Jig K4 with premium accessories to make it easy to build with Kreg Joinery. The Kreg K4 Pocket Hole Jig Master System is perfect for the woodworking hobbyist who needs a complete starter set for building with Kreg Joinery. This jig has everything, including a solid clamp, large clamping recess, dust collection attachment, material support stop and removable 3-hole drill guide. The Master System comes with a Kreg Jig K4 and bonus Kreg accessories: the Kreg Face Clamp, Portable Base and more.

Large Clamping Recess

With the Large Clamping Recess, it is easy to secure the jig to a workbench using Kreg multi-purpose Face Clamps; or, you can use any standard bar clamp or C-clamp.

Sturdy Toggle-Clamp

The Kreg Jig K4's rear-mounted clamp design is the same proven design used for the first Kreg Jig. It has superior rigidity and unyielding workpiece hold-strength. Simply release the locknut and rotate to your desired setting to make easy adjustments.

3 Tools in 1

The Kreg K4MS Jig Master System works as many different tools in one package. Because of its removable Drill Guide, it can become a sturdy benchtop jig that works with the benchtop base to create high speed pocket holes, a contractor-grade jig for working on the go via its portable base, or a high-quality repair jig when you install spacer blocks to the bottom of the drill guide.

3-Hole Drill Guide

The three-hole Drill Guide lets you drill pocket holes in a wide range of material widths and thicknesses - from 1/2 to 1-1/2 inch in 1/8 inch incremental settings. Every Kreg Drill Guide is made with a hardened-steel core with a lifetime guarantee. The core shrouds the bit and supports the workpiece through the entire drill-stroke, reduces bit deflection and results in less tear-out and a clean and pluggable pocket hole.

Material Support Stop

You can customize the Material Support Stop to be set at any distance from the pocket hole jig. This makes it possible to repeat the same pocket holes multiple times. You can also swing the stop out of the way use it as a height support for bigger panels.

Glass-Reinforced Nylon Body

Each Kreg K4 is constructed from a heavy-duty, glass-reinforced, nylon blue body. This is a composite material with maximum flexibility and resiliency while retaining the durability and strength Kreg is known for.

Superior Angle

Unlike other jigs on the market, which tend to have a shallower angle of approach, the Kreg Jig K4 Master System has an optimized drilling angle designed to maximize driving efficiency and reduce the overall size of the pocket hole. This is a very compact pocket hole at less than 1-1/2-inch in size.

Wood-Chip Relief

The Kreg K4 Master System has one wood-chip relief hole for every Drill Guide hole. This design keeps the drill bit clear of excess wood chips, lessens drill torque, maximizes the life of your drill bits, and enables you to complete your pocket hole project to satisfaction in one shot.
