Make a Pocket Hole Jig





Introduction: Make a Pocket Hole Jig

What is up everybody, In this tutorial, I am gonna show you how to make a custom pocket hole jig with a 3d printer.

With the hole jig you can drill holes at an angle which is especially useful if you want to achieve strong bond between joining two wooden pieces at a 90° angle.

Step 1: 3d Modeling and Printing

As always, I start this projects with firstly modeling it in a 3d software called solidworks. I made a seperate solidworks tutorial video:

When I finished the model I export it as stl format and slice it with simplify 3d software. Estimated printing time was around 45 minutes which is just enough to do some other household things in the meantime.

Step 2: Making the Jig

As you can see, the slicing software made some support material inside of the jig so I figured out that the best way to remove it is by drilling a hole through the whole part with firstly 8 mm drill and finish it with a 10mm one.

Now, we need to cut a small piece of an aluminum rod, somewhere around from 2 to 3 cm

I chamfer on side so It could slide in the jig more easily.

I used a small rubber hammer to push it inside and the jig is pretty much finished.

Step 3: Customizing Drill Bit

Now we need to modify the drill bit. I use an old 8mm drill on which we have have to thinner the front section to about a diameter of your most commonly used wooden screw.

Drill bits are made from a tempered hss which is very hard to cut or grind so without waisting any time I just used a grinding wheel and grind away most of the front material.

It wasn't actually that bad and It was pretty sharp on edges so I just leave it like that and now we can finally test the jig.

Step 4: Testing the Jig

Clamp it down securely and start drilling a hole until you see the tip of the drill coming through the side.

We could also machine a small drill stopper on a lathe but I find it unnecessary for making a few joints.

This is how it basically looks in the sections view and if we want to join two pieces together just use a bigger clamp to hold the parts together and put a screw or two in the middle.

And the pocket hole jig is finished.

    Really nice idea. Thanks for sharing it. I had a thought when reading through it. Instead of modifying a drill bit, you might be able to use one of these, and adjust the size of the tube to accommodate the socket:


    Have you thought about making the bottom have a v groove to be able to drill them into round dowel like on chair rungs. I going to have to print one of these thanks

    Thanks for the stl file. Did you print it with ABS filament?

    I have a Kreg Pocket hole jig kit with a lot of accessories as well. And you can buy replacement stepped drill bits fairly easy. The jig you made looks good, but I would buy the very sharp stepped drill bits if it were me. JMHO Thumbs Up!

    jp, you are right, if you use that a lot I would also recommend buying a new sharper one
