From the Manufacturer

The Kreg Jig Master System is the ultimate pocket-hole jig 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! The large clamping recess makes it easy to secure your jig to your workbench using Kreg multi-purpose face clamps or any common bar clamp or c-clamp, and the rear-mounted clamp design is 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 the innovative removable drill guide, the Kreg Jig Master can be many tools at once. First, a sturdy bench top jig utilizing the bench top base for high-speed production pocket-holes, then a contractor-grade jig for work on the road through the use of the portable base, and also a high quality repair jig with the addition of spacer blocks to the bottom of the drill guide. The patented 3-hole drill guide lets you make perfectly placed pocket-holes in a wide variety of material widths and thicknesses (from 1/2-Inch to 1-1/2-Inch, in 1/8-Inch 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.

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.

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!

I was looking at building some cabinetry for a home bar which would involve quite a few face frames. While I adore my little cheapy Kreg jig that I picked up at the homestore, I'll be the first to acknowledge that it's a royal pain to clamp and unclamp and find somewhere/something I can clamp *to* to stablize it so that I can drill the holes. Each hole takes an inordinate amount of time. So saying the main reason I wanted this was for the clamp system which has indeed made life a whole lot easier.

Mostly. Although I didn't *need* an additional step bit, I figured I could just leave one set up for the little portable jig and and other set for the face frame clamp. I am about to re-think this idea. I'm not sure what the problem is, but the bit that came with this set is horrendous. It's a good thing I've got the clamp fastened down to my workbench because I have to put so much mojo to the drilling that I about have to hang my full weight off the drill to get the job done. And this is a 1/2" hammer drill mind, not exactly lacking in power or torque. The old drill bit is just "zip, zip, it's done". The only thing I can see on close inspection of the bits and a side-by-side comparison, is that the new bit does not seem to have quite as aggressive a shoulder on the grind. Such a small thing, but apparently it makes a difference.

The case is definitely a "meh" accessory. As others have noted, just a cheap thing. I can get the same result by putting all the parts into a plastic food carrier. And I may do that just because it will be easier to store with my other small accessories.

Five stars for the wonderful clamp. Minus a star for the awful bit and dinky case, so 4 stars overall.

Update 4-22-12: There is definitely something wrong with the bit. The local homestore carries Kreg products so as I was shopping a few days ago I invested in *another* step bit - and this one drills like a hot knife through butter as it's supposed to.

I am an average DIYer. I am pretty good at reading (or watching) and following instructions, but because I'm not a pro, I am short on hands-on experience.

It seems like there is not a weekend that goes by that doesn't involve making or fixing something that requires joining two pieces of wood together. There are many ways of doing this, but few are as elegant or effective as pocket holes.

What's a pocket hole? Well, if you look at the hidden side of most manufactured furniture or cabinetry (take a flashlight), you will probably see oval or elliptical holes. If you look down inside the hole (at an angle to the surface of the wood), you will see two things: one, the hole is actually a circle; and, two, at the end of the hole is the head of a screw. That's a pocket hole.

Pocket holes and screws (or dowels, i.e. wood pegs) and glue are a really good, strong way to join wood together. When used with glue, the screws act like little clamps, pulling the surfaces of the wood together.

What can you join? Well, pretty much any two pieces of wood, at any angle. I have used mine for face framing (that's joining two pieces of flat wood together along their thin edges, like when making a picture frame), and for joining the walls and floors of your basic wooden box. (About boxes: just about every useful wood project involves building a basic box. A drawer is just a box on sliders. A cabinet is just a box with doors and shelves. A bookshelf is a box.)

Pocket holes aren't new. Apparently, the ancient Egyptians used them. But for most DIYers, they have been out of reach because they USED TO require expensive, or hard-to-find, equipment to make.

So, some DIYers like me would try to fudge pocket holes freehand.
