Default Carbide Burr substitute?

I had to break out the die grinder with a carbide Burr today to egg out some holes on a combine today. I was rapidly reminded of the fact that the burr was a creation of Satin himself for all the little metal slivers everywhere. The best thing I have found to get them off my skin and gloves is a blow gun with compressed air. That really isn't the problem, the trouble is all the slivers everywhere. Any suggestions for something else to use in the die grinder that is effective as the burr but with out the satanic residue.

There is no such thing as too much ammo.....the real problem is a target deficency.

Nope, nothing else cuts at that speed. I am always having my wife pull steel slivers from milling or die grinding. Those two machines know how to make a wicked chip.

Not quite the same, but a bridge reamer might be what you need if you have the headroom.

Yeah, if you're opening up or "aligning" existing holes a bridge reamer is the way to go if you've got room. They make stubby ones with hex ends that can get into some pretty tight spaces. I've even used a zip cutter to remove some of the taper to make them shorter...

Measure twice and cut once...or...wait, was that the other way around?

Ever notice the jobs where the slivers come back at you the worst (like reaching inside a large pipe), are always scheduled in the morning ?

so your itchy & scratchy all day.

Try a grinding wheel if you can get one in there, but they are much slower

Have you tried this ? :

I have had burrs that put out such nasty shavings that I put it on the bench grinder before I threw it in the scrap bin so that no one else would suffer. Most put out tolerable shavings. Tape a shop vac hose near the hole and it collects a big portion of them.

I stick a nice big magnet right next to where I'm cutting and that collects a lot of the splinters. Machining wax helps a little too but if you're moving a lot of metal, it just melts and makes the splinters gooey.
