Drilling holes using dremel

[mothman]

I was wondering if I could use the dremel to drill some holes on the aluminum plates. Thickness is about 4-5mm. If the answer is yes, what kind of drill bits should i use? Any help and advice is greatly appreciated.

there are better ways to drill holes than a dremel...I would use a drill press

Yea drill press would be the best way but I dont have a drill press and dont plan to buy one as I dont have any room to keep it.

I know that you said you wernt planning on buying a drill press but here is a link to some inexpensive and smaller styles, there is also a drill guide where you could use a 3/8" drill and get a near drill press accuracy

You can use a dremel to drill a hole. I use carbide-tipped bits. They make drilling easier.

azjc, thanks alot for the link man.. Really appreciate your help, but I already have the this.
The reason why I'm reluctant to buy a drill press is because I live in a small apartment and I dont really have place to put them. Besides I dont think im gonna use it that much.. Anyways, thanks again for the help..

George, how hard is it to be on the dremel? And what is the ideal speed to drill some holes on 4-5mm plates?

Just drill slow. Haste makes waste. It also helps to use a dremel that uses a/c instead of batteries.

If you have no other way and need precise vertical hole, dremel make s drill press attachment.

I have one (gift from inlaws) and a real drill press which is what always gets used for holes. I also use the AC verison of the dremel.

He already has that...




You'll be fine drilling with the dremel, and better off if you can use that press attachement. I've been considering one of those... Carbide tipped bits are definately the way to go, and just take it slow.

Didn't see that, please forgive my oversight

You don't need carbide tipped bits to drill alum, waste of money unless you going to drill something thats hardened. High speed steel drill bits will be more than enough to drill alum.

Don't need highest rpm either. Use medium RPM and feed it at a rate that generates good cutting. If its not 7075 alum, the cuttings will be long pieces at optimum rpm/feedrate. If its 7075, they will be smaller, but clean distinct pieces.

that should work (your link) I was thinking that you would be holding your peice of aluminum in one hand and the dremel in another......I have been there and it sucks, I am a big believer in using the right tool for the job
