Kreg Jig K4 Master System K4MS

Large Clamping Recess
The Large Clamping Recess makes it easy to secure your jig to your workbench using our multi-purpose Face Clamps™ or any common bar clamp or c-clamp.

Sturdy Toggle-Clamp
The Kreg Jig®'s rear-mounted clamp design has been around since the first Kreg Jig®. It's a proven design offering incredible rigidity and uncompromising workpiece hold-strength. Adjustments are as easy as releasing the lock-nut, and rotating to the correct setting.

3-Tools-In-1
Thanks to its innovative Removable Drill Guide, the Kreg Jig® Master System can be many tools at once. First, a sturdy benchtop jig utilizing the benchtop base for high-speed production Pocket-Holes, then a contractor-grade jig for work on the road through use of the portable base, and of course a high quality repair jig with the addition of Spacer Blocks to the bottom of the Drill Guide.

3-Hole Drill Guide w/ Hardened Steel Core
Our patented 3-Hole Drill Guide lets you make perfectly placed Pocket-Holes in a wide variety of material widths and thicknesses (from 1/2” to 1-1/2”, in 1/8” increments). Every Kreg Drill Guide features a hardened steel core which carries a full Lifetime Guarantee. The core shrouds the bit and supports the workpiece through 100% of the drill-stroke, resulting in minimal bit deflection, reduced tear-out, and a clean pluggable Pocket-Hole.

Material Support Stop
The Material Support Stop can be set at any distance from the jig to help you repeat the same Pocket-Hole over and over again. The stop can also be swung out of the way to serve as a height support for large panels.

Glass-Reinforced Nylon Body
The blue body of the every Kreg Jig® is actually made from a heavy-duty glass-reinforced nylon. This unique composite material offers the resiliency and flexibility you need without sacrificing the strength and durability Kreg customers have come to expect.

Superior Angle
Unlike competing jigs with a shallower angle of approach, the Kreg Jig® Master System features an optimized drilling angle specifically designed to increase driving efficiency and minimize the overall size of the Pocket-Hole. The result is a compact Pocket-Hole, less than 1-1/2” in size.

Wood-Chip Relief
Sometimes the simplest things are the easiest to overlook. The Kreg Jig® Master System includes one wood-chip relief hole for every Drill Guide hole, designed to keep the drill bit clear of excess wood chips, minimize drill torque, increase the longevity of your drill bits, and allow you to complete a perfect Pocket-Hole in one plunge instead of three!
