Help identifying this drill bit?
I'm trying to drill a 1.5" diameter hole in a small piece of walnut (8" long x 3.5" wide x 3/4" deep). I want the hole to go through the wood about 1/2-5/8" deep, so it doesn't go all the way through. I want to be able to fit a 1.5" magnet in this hole so the other side looks like smooth wood but will act as a magnet to hold keys. I finally found a video showing what kind of bit I need but I do not know what they're called and if I can use it with an electrical handheld drill. The only bits I have for this are paddle bits, but the long tip on them would poke all the way through the wood. Here's a screenshot of the bit, can anyone help me out and give me some advice? Thanks!!

Welcome to the forums.
The bit has been identified
What you are attempting to do and the depth in which you want to go would require the use of a drill press where you could set the stop depth. You couldn't hold the drill steady enough to control the bit as well as it's depth.

rbkhockey83,
I was so busy getting the bit information for you that I did not read the rest of your post.
Do you require that this be made from a single piece? I've read of similar projects where the hole was drilled the other way (no need to be as precise and you can use a spade or other bit and not need to purchase a new forstner) and a piece of veneer placed over the magnet. Then you wouldn't have to worry about drilling 1/16 of an inch too far (and you can use cheaper wood for the back).
edit: I think that a forstner bit would not produce a flat hole anyway. There is still a protrusion in the middle. If you need to do this out of a solid piece, I think that a router is the way to go. But that's only my guess, I don't have many tools

If you don't have a drillpress to control the Forstner bit, or a router, you can file or grind the long point on your spade bit down to a short nib. To prevent the bit from skating start out with your hand drill at its slowest speed until you get into the wood a little bit, then you can speed it up.
You do realize that the keys themselves are brass or aluminum...?
