The Ultimate Kit for Kreg Joinery™:
The Kreg Jig® Master System is the ultimate Pocket-Hole Jig on the market, and a great choice for any woodworking enthusiast. Between its solid clamp, large clamping recess, Dust-Collection Attachment, Material Support Stop, removable 3-Hole Drill Guide, and seemingly endless adjustability, this jig truly has it all! If you're serious about Kreg Joinery™, and even more serious about owning the highest quality tools, look no further than the Kreg Jig® Master System.

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.

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.

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 JigĀ® 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!

Kit Includes:
Includes everything you need to get started with Kreg Joinery™, including the Kreg Jig® Master System, Face Clamp™, Portable Base, Drill Guide Spacer, Material Support Stop, Dust Collection Attachment, 3/8" Stepped Drill Bit, 6" Square Driver, 3" Square Driver, Starter Screw Set, Starter Plug Set, Quick-Start Guide, SkillBuilderT DVD , all inside a durable carrying case.
