Wood Owl Auger Bit

[Woodworking_Hobby]

Has anyone used a bit like this?  Marc had recommend one for drilling 3/4 dog holes (I think) but I am not sure if I am using it right. The threads at the bottom of the bit are almost self drilling and it either tries to pull the wood out of my hand or if I clamp the wood the bit almost bores itself and I feel like I have lost control of the speed of depth. Do you have to use super slow or is there another trick?  Anything better for deep 3/4 or 1 inch holes?  I have some forstner bits but did not think you wanted to use them super deep into woods.

This bit is way too aggressive to be used to drill dog holes. I’ve used those in construction to run wires thru 2x’s and the holes are not pretty! Maybe you saw him using a brad point or fortsner bit?

Screw-point augers work best in a brace. The screw is designed to pull the bit into the wood, to reduce the pressure the user would otherwise need to apply.

If you only have a drill motor, try the lowest speed it will manage.

Don’t handhold Anything while trying to bore with that. 
 

Ross, even with a brace, the lead screw needs to match the hardness of the material. Softwoods and hardwoods often require a different lead screw taper.

You want to order this bushing.  You mount the bushing in a piece of wood and use it as a template to start the hole.  You will probably need to remove the bushing template to finish drilling to the full depth of the hole.

And this bit in 3/4 inch size.  Make sure you select the 3'4 inch bit from the drop down menu.

@Chet , that bit has a 3/4" shank.  Do they have one with a reduced size shank?

I used to have a 1" auger bit in my camping kit, pretty much something like this:

A branch was inserted in the eye of the bit to use as the handle. Unfortunately I lost it and never replaced it. It was a nice a tool for making contraptions and temporary stoves.

That lead screw looks just like the ones on my self-feeding plumbing bits.   It pulls the bit in as the rest of the bit cuts.  They use the same lead screw on bits that I have up to 3-5/8".  On the big bits, the lead screw is replaceable.
