I found one of these in the filing cabinet when I was cleaning it out. Its a bit different than what the pic shows, it had an angle like a rounded off triangle

(The thing in the drill press)

Does anyone know the name of the bit and where I could get more like them? I thought they are milling bits, but I looked that up and got something totaly different.

Its the 2nd pic

Ok fixed

well if your looking for it to use in your dremmel here a linky
http://www.tools-for-woodworking.com...ory=443&Page=2

we have them at work for our drills but i dont know what you would call it.

heres the closest thing i found "annular bits"
http://www.csunitec.com/magneticdrills/cutterssmll.html

i dunno if that helps

Actually, It did help me! Because I found what they are called (I think..).I believe they are called End Mills
http://en.wikipedia.org/wiki/Endmill

Or they are Reamers...

But this page says other wise
http://www.american-carbide.com/EndMills/EndMill.aspx

They look Exactly Like that! Now I just gotta get an assorment pack

that is a two flute endmill. made for rough metal work.

almost any machine shop or machine shop supply will have them in every size up to 1" .

i highly recommend a 2 flute for rough work and a 4 or 6 flute for finish work.

also you gotta adjust the revs on your dremel to use them. they specifically cut certain metals at certain speeds, too fast and the cutter burns. too slow and it chops. a good speed will go in and cuut easy with no vibrations or bucking.

you can use them to drill in to a metal and do depth cuts as well. very versitale items.

2 fluts cut aluminum and steeel well amost multi purpose. the 4flute and 6 flutes can do aluminum as well but prefer a slightly harder metal if i remember correctly.

make sure you get a roughing cutter and a finish cutter or just get the finish cutter. the roughing ones leave very noticalbe machine marks and are a pita to file out.

i did machining for 2 years and still have a few big endmills lying around. What metal are you cutting Nerdz?

Well I was actually going to use it with the 5 speed drill press I have. I plan on mainly cutting plexy glass (well acrylic, 1/2 thick..) and maybe copper (But thats wayy in the future probably). Im going to attempt to etch a peice of plexy with it instead of the dremel, since I noticed that the deeper the cut is in the plexy, the greater the effect. I was going to get a small 1/8 or if possible, 1/16th 2 or 4 flute. Which would be best for plexy? What speed should I use for plexy?

edit- opps wrong post to edit

well in plexi, i think you want 2-3000 rpm going and you want a 2flute to do the roughing and a 4 flute to do the finish.

you may want to go 1k rpm first and do layers down cutting the design out so the plexi doesnt heat melt.

we had large coolant units for the auto mills and for the hand stuff a coolant spray bottle of which we used liberally on plexi.

the slower the rough cut the better then go faster for the finish since your realyl just evening out the edges and cleaning the lines.

So Im guessing use the same method for copper except faster? I dont really know the speeds precisely, it uses this belt drive system, I'll look in the manual to see what it says whats the speeds are.

5 Speed, 620 - 3100 R.P.M. (Yea I said 8 speed before, but its an 8 inch 5 speed drill) I cant seem to find the manual but this is my drill press, http://www.toolcenter.com/8050.html

go slow and start on a scrap piece that you can ruin. and tune the speed to a rough cut and a finish cut .

if your working with plexi and you can tune the finish right, you can get a flamed finish to the cut since its hotter on the 4 flute. there should be an idicator of some sort of the speed, but if not just dial it in. mark it on the dial, and go to work. i think youll be fine.

Looks like my drill press (except mine is red). Not a great precision machine. I have not tried to mill anything yet, I've only use it as a drill. I don't know how well it will work for you, I'm a little apprehensive to try on mine for fear of the mill bit doing the rhumba while I'm working. Please post your results if you go ahead with this.
You may need a different collette if you mill?

Yea, I found the speeds, its on the side of the thing on top, except it doesnt say that it goes from 620 RPM's to 3100rpms, the diagram shows it goes a bit higher.

But how come the dremel bits and the end mill bits look different?

Well, It dependings on the drill bit. Ive had it drill accuratly and right on. I dont have a XY table though for it too mill, but I have tried milling my own block. It took a looong ass time (unless, I was using the wrong bit and thats why it was taking so long) I was milling AL, and was using vegtable oil for lube. The milling machine is the only we dont have, but I figure why spend the money on a milling machine when all it is is a drill press with an XY table.

XY table, $109 http://www.littlemachineshop.com/pro...ProductID=2008

Not bad, then all you would need is the vise to go on it .

the difference between a true milling machine and a drill press is precise feeds and speeds. when i needed something done right and when i need it right the first time, ther is nothing like the 25000 dollar semi computer controleeed mill at my old HS machine shop.

but all you need is to make a mark in one color that stands for plexi where it mills correctly for the two flute, then another for the 4.

failry simply. it is a little trial and error but itll get you damn close.

Well I'll be the one feeding it, the drill will pretty much stay at the same height, all I have to do is push it. Any error that is made would be my own.

Is where I am getting them from. Im still deciding on size though. I dont know what would look better, I might go with 1/8, but it seems a bit small. They do have 3/16, and 1/4 is too large.

And oh! I found them (the things that look like the dremel attachments
http://www.american-carbide.com/Burs...ection=0&Cat=2
Burrs is what they are called. Those are what I used to mill my AL, Im guessing I shouldnt have used them now since they are for other things.

What are they used for?

i never had to tap into those but id imagine a finish work or etching. we used a 1/16 2 flute endmill for engraving aluminum for keychains etc. and it did just fine. but if you wanted a rounded edge that would be the item to get.
