Product Description

Note: The Kreg Carry Case is no longer included with this jig

The Do-It-Yourself Kreg Jig® with Bonus Accessories

The Kreg Jig® K4 Master System is a great choice for any woodworking enthusiast. With its solid clamp, large clamping recess, dust collection attachment, material support stop, and removable 3-hole drill guide, this jig truly has it all.

Large Clamping Recess

The Large Clamping Recess makes it easy to secure your jig to your workbench using Kreg multipurpose Face Clamps or any common bar clamp or C-clamp.

Sturdy Toggle-Clamp

The Kreg Jig® K4’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 locknut, and rotating to the correct setting.


Thanks to its removable drill guide, the Kreg Jig® K4 Master System can serve as many different tools: a sturdy benchtop jig which utilizes the benchtop base for high speed pocket holes, a contractor-grade jig for work on the road through the use of the portable base, and a high-quality repair jig when you add spacer blocks to the bottom of the drill guide.

3-Hole Drill Guide with Hardened-Steel Core

The 3-Hole Drill Guide lets you drill pocket holes in a wide variety of material widths and thicknesses—from 1/2″ to 11/2″, in 1/8″ increments. Every Kreg Drill Guide features a hardened-steel core, which carries a 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 holes over and over again. The stop can also be swung out of the way to serve as a height support for larger panels.

Glass-Reinforced Nylon Body

The blue body of every Kreg Jig® K4 is made from a heavy-duty, glass-reinforced nylon. This 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® K4 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 11/2″ in size.

Wood Chip Relief

The Kreg Jig® K4 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 just one plunge.

Frequently Asked Question:

Question: Can I use any screw?


I wouldn’t use any other screw than a Kreg. The cost difference is relatively small, and their screws are far superior.

  • Self-tapping tip reduces chances for splitting.
  • Deep square drive never strips out.
  • Very hard steel; i’ve never had one break off in the hole (the frustration from having this happen even once with another screw will have you thinking as I do almost immediately).
  • They have a screw for everything.
  • Threads only go up 1/2 the screw, this prevents the screw from pushing the two workpieces apart.
    (Maybe the most important) Kreg screws have a flat bottom head which creates a solid joint and prevents splitting. This is a major difference Kreg has over many others.
  • They are designed to be the best option for pocket joints. You may be able to go to a hardware store and buy similar screws at a better price, but be sure they have self-tapping threads.

Kreg Screws are available in two main thread types:

Coarse thread – work best in soft woods
Fine thread – works best in hard woods

    I have been totally blown away by the Kreg pocket hole system. So simple to use. So quick to implement. So fast for the job on hand. A real winner. The K4 kit includes a useful clamp as well. I’m not convinced about the need for the dust collector (vacuum attachment) but nevertheless its there if you want it. A great and innovative product.

    It took me a while to get any pocket hole jigs/tools since I don’t like the appearance of pocket holes.
    That said, they are extremely useful in some cases – like mounting table tops or seats onto their bases or for projects/jigs where speed of build is more important than appearance.
    I ended up with a holiday project where I could use pocket hole screws that were completely hidden in the final assembly and would really simplify the glue up process by reducing the number of clamps I would require. I got the K4 Master System since the K5 was quite a lot more expensive at the time when considering all the extras supplied with the K4 Master System.

    Let’s start with the positive aspects:
    (1) The build quality of all the components is exceptional.
    (2) The dust/chip collection works really well – with my shop vac + home made cyclone setup almost no chips are ejected when removing the bit from the jig
    (3) Very simple to setup with the markings provide on the jig – no additional charts required to set the collar. The markings are also stamped into the plastic so even if the surface is scuffed over time you wouldn’t have problems with setup.
    (4) The kit is very well equipped as shown in the images in the listing. The only big item not included is the 90 degree clamp, but it is possible to simply use a scrap of wood to clamp the board using the face clamp (or any other clamp).

    There are also a few downsides (some of which has been addressed by Kreg in the K5):
    (1) With large boards leaning over to release the material is a bit annoying. The K5 has a front handle for the material clamp.
    (2) The kit does not fit in the supplied case. The clamp is provided in a separate box. Not a huge problem – just a tad strange.
    (3) Imperial units 🙂

    This is a excellent product. A must have, one of the best tools I have ever bought. The Kreg slogan is absolutely true ” stronger, better, faster”.

  4. Rated 4 out of 5


    I absolutely love my Kreg Jig! So easy use! Makes woodworking a dream! My only regret is that I purchased mine before the metric ones were available, so now I have the Imperial measurements (inches), which means I have to keep on converting. Needless to say, you can print a table off the internet, and you eventually get used to the conversions. But, I love it! Highly recommended!

    I had a J3 jig which I enjoyed using and recently purchased a metric K4 Master kit which makes life so very much easier. This is a brilliant tool and I strongly recommend it.
