Jig Master System

Thanks for the questions. The Kreg Jig 320 is beneficial for clamping the jig to larger wood material.

The one that I bought didn't come with a plastic case. It came in a sturdy cardboard box that securely closes and has a plastic handle.

No...It is preset to drill at, I believe, a 15 degree angle. If it could drill at any angle, you'd have one helluva time joining the wood without breaking through the other side. Kreg puts out a rotary wheel for your shop...you turn it to the thicknesses of what you want to join & it tells you what length of screw to use...mine set me back 5 bucks.

No. That is a separate drill bit that does not come with this kit.

Yes, as long as you use the drill bit without the depth stop collet or a drill bit with the same diameter. Your angle for the drill bit guide will always be the same.

If this is a dining room type table then you would be better served to use a table leg corner bracket. If it's a smaller table the instruction book should tell you how many fasteners to use, which screw to use based on material thickness and type of wood.

I have actually come across this same issue when I was building my computer desks. I was connecting the tabletop (3/4") to the frame (1-1/2"). The solution I came up with was to use the proper screw but not drive it in as far as it would possibly go. If I did, it would expose through my tabletop (don't ask me how I know this, haha!). So I would just advise to be careful and as soon as the screw is out of sight in the hole (when looking straight-on), stop driving it. You could try using the smaller screw, but I think when I drove it in, it didn't give enough "bite" for me to feel confident in it. That's also something I did. I drove the screw in without the top on initially so I could see how far the screw would stick out once driven in the hole completely. You can do this as well and find a screw that works for you or use my method mentioned above. You'll want to keep the proper depth setting for the 1.25" leg however, or the screw will not exit in the middle of the edge of the board and you will not get as strong of a joint. Happy Making!

Yes, this jig systems consistently repeats hole spacing. The vertical placement of the board ensures that the holes are always the same distance from the end of the boards. The index marks make it easy to set depths consistently, depending on the size of the board.

Yes. I love this jig. It is perfect for joining legs for tables and chairs. It's very easy to use and does a perfect job every time as long it is set up properly.

The clamp is an extra tool, very useful in the wood shop and it is also sold separately for about $20
