New member. Is there a bearing guided carbide burr for contour shaping?

[frascati]

I asked this question in a machining forum and got no response yet. I'm attempting to reproduce a precise profile (without access to many precision tools) in a cutting edge for some diy router bits. THe bit below is for cutting MDF at slow rpm. The metal shaping bit I'm asking about is actually for producing the edge for future bits of this type.
This is a first attempt with mild steel angle iron which worked very well but lost its edge pretty quickly.

This is intended for use in a drill press at 800 rpm only and not for any commercial sale. My own use only. It occurred to me that what I'm doing is very similar to cutting a blank for a knife so I came here. I have a variable speed router table. If I could find something like a .5 inch shaft 1.5 inch carbide burr with a 1.5 inch ball bearing guide, similar to the guided edge trim bits on cabinet making trim routers, I could use it with a template to make extremely accurate copies of small profile cutting edges right on my router table after roughing the profile with a jig saw.

Anthing like this exist?

Thanks so much,
Brad.

Routers and metal, especially controlled by hand are asking for trouble. Just my .02

That's it? Just hand wringing from the resident school marm?

Well, I'm the head mistress of resident school marms......
and this is a dumb idea. Using a router and woodworking equipment to do what a lathe is made to do is just asking for a trip to the emergency room.

Filling out your profile would be polite,too.

If you will excuse our bluntness, we will exclude your rudeness.

I will be more blunt than Stacy
You are asking for metal flying all over the shop at penetrating speeds, you are out of your bloody mind if you think you can hand feed a piece of carbon steel into a rotating cutting tool without having something turn into a bullet or spear.
fill out your profile
metal is a whole different world than MDF
read the stickies
don't do something lethally stupid

Look, go ahead and ban me right off the bat here, but this is just nonsense. I asked for any heads up on whether something like I described was available.

A simple yes or no might suffice. Now TWO MORE school marms with nothing substantial to add. Each more fawningly indignant than the last. For god's sakes ladies. I've given tips on safety myself. I recently pointed out the danger of using chlorinated solvents like brake cleaners to prep welds. The gassing can kill you while welding if any of it is leftover. I offered that because it is a concern that could easily be unrecognized by an ADULT.

A fine carbide burr, with a guide template, on a router table, is by no means any more dangerous than shaping a piece of metal on a grinding wheel sans tool rest. Yeah, your high school shop instructor will tutor the kids that thats forbidden and EXTREMELY dangerous. I've done it. You've done it. You know it's no big deal. And if you mentioned it on a forum and three people ignored your original question just to lecture you on good bench grinder etiquette you'd be a little put off too.

Good day. And spare me any more of your hurt feelings. I won't be back to listen to them.

Bummer- My original intent was education in case you were not aware of the ramifications of your endeavors. I guess that would make me a marm of sorts.. It's a shame that the response to your question was polite, but you seem to want to discount it and resort to petty name calling.

If you took my response to your inquiry as an insult, then I apologize. I believe all the responses had your safety in mind.

Try to have a good day!
