K4 Pocket-Hole System

Thank you for your inquiry. When using 2x material, you will be using a 2-1/2" screw.

If both boards are 2x4’s (1 1/2” thickness), you should use 2 1/2” screws. Here’s a good link for a reference:  https://industrydiy.com/woodworking/kregtools/kreg-jig-settings-chart/

The K5 is larger and meant for bigger pieces of wood and it also has a built in clamp and dust cover. The K4 is moreso for DIYers and smaller. Both are great.

Yep! I’ve used it on 2x4s plenty of times.

Yes

Thanks for the questions. The Kreg K4 will work with your standard 2x4 that is 1 1/2" thick.

It will. I have used this many times with 2x4s and they are solid joins.

Given the depth settings and clamp depth it will certainly create pocket holes in 2x4 lumber.

Exactly, its all in the booklet identifies wood thickness etc.

Yes, it is removable and can be used without the base. I’d recommend going to Kreg website and watch videos, i found them very helpful.

The drill guide will come out of the unit, but and you could clamp it to a piece of wood - it doesn't have positive stops like the units that are specifically designed for this task so I never used it in this manor. Removing the guide does make cleaning the whole unit easier.

Yes, it comes out and you could clamp the drill guide to your work piece.

Not sure if you can use it without the base, but I’ve never had the need. Using the system has always been easier. As for the guides, there are locks and guides for screw length and wood thickness.

There is a small sampling of various types and sizes, coarse for softwoods and fine for hardwoods. If memory holds true, 1", 1 1/4", 1 1/2", and 2" lengths. These are special designed.pocket screws.

It comes with an assortment of 50 in various lengths and purposes. You select the right one based on your material. Most are 1 1/4 in both hardwood and softwood screw threads.

I purchased my kit with the starter kit. It included: 50 1" screws, 100 1 1/4" screws, 50 1 1/2" screws, 30 2 1/2" screws, and 30 2 1/2" blue kote screws.

Thank you for your inquiry. This will come with 10 pack of each of the 2-1/2, 1-1/2" coarse, 1-1/4 coarse, 1-1/4 fine and 1" coarse.

I no longer remember what sizes came with it (I bought mine 2-3 years ago) … but I bought a second large screw pack at the same time, and it has sizes for everything.

No ! Just place on a flat surface!

It does not need to be mounted to a table top for use though, in some cases, it helps to have it mounted. Most of my work is performed with it unmounted to a work surface.

I believe one of the kits comes with a clamp, this one doesn’t. However, you can easily clamp this jig with a metal clamp, it’s designed for it. I have never found the need for a clamp and do the drilling on my workshop floor

Clamping onto your bench or work surface insures that no movement will occur while drilling.

Clamping it just makes it easier. You don't have to though.

You can use this without mounting it or clamping it to anything. However, I have mine mounted to a board for extra stability and have seen other folks who have made trays where the wood you are drilling sits flush with the platform

Clamping is necessary to prevent jig from moving.

I clamped it. The pieces I were doing were long, so it made it easier only to clamp the wood to the jig and not worry about the jig moving.

The unit will sit flat, and this may work for really small work pieces, but i have always clamped mine, and I wouldn't imagine using it without doing that. There is a great surface just behind the riser to accept a clamp.

Thank you for your inquiry. For the best and safest use of the K4, we recommend clamping or screwing the Jig to your work space.

Take the drill shoe piece off and clamp that to the work piece

I don't believe there is a screw which would work in thin ply wood. This tool did come with an additional "jig" which I was able to clamp to 3/4 inch and it worked just fine

They make one for sheet goods that use with a clamp. I have one and very easy to use and works on all plywood thicknesses

I have not done that, but I do believe that would be easier. I have not used it with plywood.

I have drilled full 4x8 sheets. I typically leave the sheet laying down & clamp the jig to the sheet & drill.
