Kreg K4MS Pocket-Hole Master System
The D.I.Y. Kreg Jig®
The Kreg Jig® is the perfect choice for DIY’ers and anyone new to Pocket-Screw Joinery. Whether you’re building your first set of garage storage shelves or making simple repairs around the house, the Kreg Jig® can help you finish the job in less time, and with far less effort than you ever thought possible. Its simple design gives you the confidence to start the project, and with joints as easy as “Drill. Drive. Done!” – you’ll actually want to finish it.
3-Hole Removable Drill Guide
Our patented 3-Hole removable Drill Guide lets you make perfectly placed Pocket-Holes in a wide variety of material widths and thicknesses, without ever having to release the clamp and reposition the workpiece. The Drill Guide can be removed completely from the benchtop base and used for making repairs just about anywhere.
Hardened Steel Core
Drill Guides are subject to direct contact with the drill bit every time a Pocket-Hole is created. The core of every Kreg Jig® features hardened steel which carries an exclusive 100% Lifetime Guarantee. The Kreg Jig®’s core shrouds the bit and supports the workpiece through 100% of the drill-stroke. The end result is minimal bit deflection, reduced tear-out, and a clean, pluggable Pocket-Hole fit for finish work.
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.
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.
Glass-Reinforced Nylon Body
The blue body of the 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.
Unlike competing jigs with a shallower angle of approach, the Kreg Jig® 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.
Sometimes the simplest things are the easiest to overlook. The Kreg Jig® includes 1 wood-chip relief hole for every Drill Guide hole, designed to keep the drill bit clear of excess wood chips, minimizing drill torque, increasing the longevity of your drill bits, and allowing you to complete a perfect Pocket-Hole in one plunge instead of three!
Includes everything you need to get started with Kreg Joinery™, including Kreg Jig®, Stepped Drill Bit, 6” Square Driver, Starter Screw Set, Starter Plug Set, SkillBuilder™ DVD, and Quick-Start Guide, all inside a compact and durable carrying case
