Tool Questions can somebody help?

[Michelle K linnane]

I want to knotch or a better word is burrough out a hole in a 4 X4 but in the center and it will be a circle what is the tool an electrician using when drilling thru 2 X 4 wall studs. The only thing is I only want to go 1 inch deep in the 4x 4.

I love to use air tools they are so powerfully who makes a good aircompressor drill? I assume they make one, tire of weak drills want something with power.

any advise is welcome fellows.

You are probably looking for a hole saw , Electricians use a right angle drill with a hole saw bit. You could also use a router if you have one.

Sounds like you want a Forstner bit, like this one:

Forstner bit

It makes a flat bottomed hole. A hole saw will only cut a ring if it doesn't go all the way through.

I used a selfeed bit to drill holes through framing for plumbing and electrical when I built my place. If you are only going 1" deep, you'll have to go slow since the bit will grab and dig down fast. If you want a cleaner cut on the bottom, you may want to use a forstner bit.

When using larger bits, I'd strongly advise using a right angle 1/2" electric drill (same style as Milwaukee Hole Hawg).

If you have room to work a cheap Spade bit will work fine. Even on a regular 1/4" drill.

Forrester bit is the best for a clean & accurate hole.

Hey Guys
A picture is worth a thousand words. I do not spending the money on a tool
so long as it makes the job easier. The size of the hole maybe at least an inch
and in PT wood that might be awfully hard drilling?

Also if I use a hole saw how do I get the wood out once I drill in an 1 inch?

You're actually asking about how to drill a blind hole (hole that is not through the wood), is that correct?

You can use something like this:

And, a trip to your local hardware store may be advised. Ask for a Spade Bit (shown in the attached picture)

The forstner bit is probably the way to go . Or spade bit

A new spade or forstner bit will do the job just fine even with a 12-14 volt 1/4" cordless drill. No need for air tools or expensive drills. The bit is the key on this size hole. If you need to do a lot of them get a forstner bit like one pictured with serrated edges in a previous post since spade bits can wear down pretty quickly. Don't get an expensive woodworking forstner bit (they are designed for use in drill presses - not hand held drills). The pictured type is what you want although I prefer to just buy new spade bits for this type of project because they are cheap and easier to use with low power drills. As mentioned in another post, electricians use auger bits. Don't try to use an auger bit for a 1 inch deep hole. Also a hole saw would not be ideal for your project (I've never heard of an electrician using a hole saw in 2x4s either - that would be very inefficient). If you have one though, then you've got to knock the plug out after drilling 1" deep with a chisel or screwdriver. It might be hard to get a flat-bottom hole this way unless you are pretty good with chisels. In every case you can wrap some tape around the bit 1" back as a guide so you know where to stop.

Chicago Pneumatic, unless you want to spend enough money to get a Sioux.

But you'd better have a lot of CFM's coming out of that compressor as air drills sure gobble it up.

Yep, I'd say 4 to 8 CFM depending on which drill and how long you need to run it continuously. Unless you want to get serious with something like the Sioux T-Handle drills that may use up to 35 CFM.:laughing: I worked on a bunch of the old Sioux T-Handle drills and they're really impressive.

Michelle it would help to know what your end goal is. Do you need a flat bottom hole or just one that has a 1" diameter hole 1" deep where the bottom shape doesn't matter. No need for new tools if you have an existing drill of some kind. The bits mentioned will all work. Do hold on tight when you make the cut. Pressure treated wood is generally very wet when new and can bind up a drill bit. Make your cut in 1/4" steps pulling the bit out to clear the hole of wood cuttings. If the 1" depth is critical a piece of masking tape on the bit works well as a guide.

Journal of Light Construction or Fine Home Building, I forget which one, did a test on spade bits and Bosch won hands down.
