Aluminum carbide burrs
Anyone know a good source to get these? I'm looking to do some porting work. Also, what's the best way to keep these from "loading up" with aluminum? I've heard of using things from WD-40, to automatic transmission fluid or even wax? Just looking for personal experience I guess, thanks!

Re: Aluminum carbide burrs
cutting wax works good.
sorry, dont have a supplier off hand for the bit.
an old school trick is to put shaving cream in the ports before you grind. its easily washed off at the end with water,...then compressed air.

I got mine off eBay. I believe they came from Oregon. I used them to gut my plenum, SLP runners and intake. They're still very sharp and the best part is they were only $6 each.

BTW, I had no issues with them loading up with aluminum. I used no cutting lube.

Re: Aluminum carbide burrs
i used martindale burrs when i ported my crossfire manifold-they did start to load up when i ran them too fast,but when i slowed down my electric die grinder with speed control no more loading.These burrs were a little expensive,something like $60 in 1994-hate to see what they would cost today...

Re: Aluminum carbide burrs
Summit has them. Expensive though. I'd browse ebay. They do the job.

Re: Aluminum carbide burrs
The burrs for aluminum are different than regular carbide burrs designed for steel. They look more like a burr designed for wood and won't clock up as easily. I only have a couple and bought them from Snap-on.
Do a quick search on Ebay for "aluminum carbide burr" and you'll see what I'm talking about.
If you try to use this style with steel, you'll break the edges off.

The burrs for steel will work fine on aluminum, I've used them on more than one occasion, just make sure you turn the speed down a bit, if you go at it at 35K RPMs, they WILL CLOG. I recommend turning them down to 15-20K RPM and they should stay pretty clean.
either way, the bestcarbide.com link I posted earlier has everything you could possibly need in the way of burrs.
