Angled Holes

Hi all. I am making some angled holes. I am using my drill press table set to 30 degrees, the drill press is on its slowest setting (620rpm), and I am using a 2.5in forstner bit. I know I need to be patient but its taking forever to make a single hole; right now I am only practicing on 3/4in scrap. I am applying slow even pressure the best I can, but the bit still binds up.

Anyone have any hints or tricks to make this process easier and faster? I was wondering if I should cut a smaller flat hole and then try to go over it with the right size angled cut.

Thanks,
Jeff

Jeff,

How deep are you cutting the hole? 2.5" is quite a bit of material to drill.

Now my question would be are you going to drill all the way through the board? If this is the case, I would use a hole saw instead of a forstner bit. A hole saw will have quite a bit less friction so it wont stall as easily.

If you are making a pocket (not drilling all the way through), then I would do the following:

The next way I would do it is to make a jig by cutting a 2.5" circle and use a router to follow the circle and cut into your part which is placed at a 30 degree angle with respect to your jig. I am going to have to learn how to get drawings on the web so I could show you how this could be done.

Cheers,

Ben

Definitely a forstner bit is not suited for that type of task. Doing this Saw Horse I used a jig in hardwood, about 2" thick with a hole in the desired angle…....I used a regular "hole saw" with good and clean results. also a "Plug" cutter could work at your drill press.

I forgot to mention: When I was doing the firt hole at the jig, I used a larger guide bit on the Hole-saw, so it guides the 2.5" sawing. Let me know if you need more specific drawings

I did a little experiment. I used the bit straight on the wood and it made a nice round flat hole with no binding or stopping. Then I took out some smaller hole saws I had. For what ever reason (I am guessing the teeth are making the difference) the hole saw works much better on the angle. Thanks for all the help!
