Where to get steel carbide die grinding bits.

I have never bought these before. Does home depot have them? I would assume they do, I just am not sure if its a specialty item.
Thanks,
Jason

Re:Where to get steel carbide die grinding bits.

yeah I know they have them for dremels, I guess I was kinda vague, I meant for a air die grinder. I need to take a good about of metal out of my adapter plate, so I was looking for somethign more heavy duty. I believe the standard chuck size is 1/4 for air grinders? Am I wrong?
Thanks,

ah... ok... 1 hint of advice... if you make a groove from your Manifold to the Adapter Plate... Use a Makita (portable) disc grinder... and start grinding away... Saved my *** at least an hour.. cause the rotary file wasnt cutting it...

I used an electric angle grinder with a disc and it took that steel down QUICK!. Do that first, then finish up with a carbide bit.

P.S. I've seen a pack of 4 on ebay go for 30 bucks... it even had a "buy it now" option!

Re:Where to get steel carbide die grinding bits.

well see here is my problem. I bought a plate from gary and randy like a year ago when they first were selling them. But I noticed now that I finally have gotten around to finishing my project that they either gave me the wrong plate with a smaller hole, or I ordered the wrong one. The hole is alot smaller then the hole for the HF manifold. SO I want to port match it, but there is a lot of material to take off. Do you think a small disc grinder would be the best? I cant think of a easy way to get that much material out.

Re:Where to get steel carbide die grinding bits.

The inlet of the IHI is very small compared to the HF manifold (which is what I'm using).

I had a machine shop make me the adapter, but they didn't port it. That's when I pulled out the angle grinder. It has a large wheel on it, and it grinds steel down nice. It took me about 15 min to cut all the steel out (which was a lot). My problem is that the wheel was too big, and I could only cut so deep, so I have to finish up with a carbide bit.

btw, the angle grinder I have only spins at 11,000 RPM, so anything higher than that is PLENTY with a cutting wheel.

I've never used an air die grinder with a carbide bit before, so I can't estimate how long I have left to finish. That will probably take a little more time.
