Sturdy Toggle-Clamp
The Kreg Jig Master System features the same reliable rear-mounted clamp design featured on the very 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.

In addition, the large clamping recess makes it easy to secure the jig to the workbench using Kreg's multi-purpose face clamps or any common bar clamp or c-clamp.

Removable 3-hole drill guide.

Three-Hole Drill Guide with Steel Core
The patented three-hole drill guide lets you make perfectly placed pocket-holes in a wide variety of material widths and thicknesses. Every Kreg drill guide features a hardened steel core that 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.

Durable Construction and Optimized Drilling Angle
The blue body of the every Kreg jig is made from a heavy-duty glass-reinforced nylon, a unique composite material that offers the resiliency and flexibility you need without sacrificing strength and durability. To increase driving efficiency and minimize the overall size of the pocket-hole to less than 1-1/2 inches, this system also features an optimized drilling angle.

Wood-Chip Relief Hole Extends Bit Life
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.

What's in the Box
Kreg Jig Master System, face clamp, portable base, drill guide spacer, material support stop, dust collection attachment, 3/8-inch stepped drill bit, six-inch square driver, three-inch square driver, starter screw set, starter plug set, quick-start guide, SkillBuilder DVD, and carrying case.

5.0 out of 5 stars The Fastest, Easiest Joinery Method December 28, 2010

By Jeremy

If you do any kind of woodworking joinery, the Kreg will make your life easier.

I have used this jig to build:

- a crosscut sled for my table saw (.75" birch ply)

- walnut cabinets for my master bath (.75" walnut, .75" birch ply)

- amp cabinet enclosure for a red-knob Fender twin (.75" birch ply)

- Speaker enclosure for another guitar amp (.75" birch ply)

- A bathtub surround for a whirlpool tub (1.5" 2x4's and 2x6's, some 22.5 degree angles)

- others

This is hands-down the easiest method to join pieces I have ever used.

Pros:

+ It will join pieces at a 0 degree angle and at a right angle.

+ it will join pieces at any other angle

+ works with material thicknesses up to 1.5" (2x4's etc)

+ it is SUPER EASY and intuitive to use

+ When joining the pieces, the screws pull the pieces together, so sometimes clamps and glue aren't necessary if face alignment isn't critical.

+ the screws are cheap and readily available (Amazon, HomeDepot, Lowes, Woodcraft, etc)

+ The joints are strong

Cons:

- While the face-clamp is crucial for alignment, it's not always enough... the screws pull and will often pull stronger than this clamp. Therefore, I use a bar or pipe clamp across the long dimension to hold things absolutely still when driving the screws

- It becomes cumbersome to move the jig several times on long pieces. (they do sell pocket hole machines for production, but $$$)

- I only use pocket joinery on joints that either will be invisible, or I don't care if the holes are visible. I haven't had good experience with the plugs.

- The stop ring has slipped on me a few times, causing me to drill a few holes in my jig, and through my workpiece. If you see blue plastic in the sawdust, you'll know.

To summarize: I CAN'T RECOMMEND THIS JIG ENOUGH! It is a huge time/headache-saver. I'd pay twice this much for it in a heartbeat.

5.0 out of 5 stars Kreg K4 Jig: Pocket Holes are Fun December 16, 2010

By Mario Leal

I will start by saying I am a complete beginner to woodworking. I only have a couple of power tools: Circular Saw, Jigsaw, Corded Drill. This Christmas (2010), I mentioned to my wife that I would like to do some woodworking, and she jumped at the chance for "cheaper" gifts. Now, I have a good long list of tasks to complete. I was worried about how I would learn joints fast enough to be able to build anything at a mediocre standard much less presentable for gifts. In comes the Kreg Jig. I saw it on a YouTube video and immediately bought one.

First night out was slightly slow due to not knowing all the parts, and the included instructions aren't very good. It's the DVD that really helps you. After the first 30 minutes of becoming accustomed to the jig, I was quickly building the bench from the Kreg website. The pocket holes were perfect and easy. It took me longer to finish the cut list then it did to assemble! I am happy I picked up this wonderful tool at the beginning of my woodworking adventure. It has saved time and got me started.

That being said, I will still learn other joints (rite of passage?), but Kreg has made it a real possibility that my Christmas gifts will turn out well.

Kudos Kreg!

3.0 out of 5 stars What are you geting for the price??? February 9, 2012

I recently received my Kreg Master Jig system after procrastinating a long time about the purchase. While my use has been minimal I do have some preliminary impressions.

1) The Jig itself is very study and works quite will. The plastic was of a much higher grade material than expected and a little bit of assembly was required. Learning how to operate the tool couldn't be easier.

2) The case is ridiculously bad. We all know there are two type of handymen in this world the kind that care for their tools keeping them neat and organized and then there are the handymen who just toss their tools in a junk pile after some abuse. This case basically amounts to a junk pile. The only thing you can do is toss it all in the box and shut the cheap plastic lid. I doubt this would last very long in contractors pickup truck.

3) The extra components included in the master system are nice but the only essential part is really the clamp. However the clamp doesn't fit in the case, so I guess you can carry that around some other way.

Over all the this is a good "Tool" and is already beginning to add value in my workshop. However, I would be so much happier with a case the let you organize your parts. The tool itself is 5 stars but I took off star one given my perceived price / value ratio and I removed another star as a result of the case. At the end of the day buy the tool but think about getting a small tool box from the big box store so you can keep all your parts, clamps, and screws in one place.
