Where to buy bulk grinder wheels?

Lehigh Valley Abrasives

I just bought a dozen HF flapdisks this weekend cause I was out and it was nearby.

At $3 each im pretty happy with em.

Roark Supply FTW

Yeah be careful with the cheaper cut off wheels, I have had serveral do this on me

we used to use the pferd cutoff wheels at work and they cut like a laser but if you got them in any kind of bind or put a lot off pressure on them they would explode. we started getin 3m cubitron and they are great they cut fast last for a while and they don't blow up easy. that being said they don't cut quit as thin of a line but its worth the trade off I don't know the price but worth looking in too. we use the cubitron flaps and pads and I love them the pads last a long time while cleaning up welds. and the flaps work great fish mouthing tube and putting a good finish on any part. I could post a pic up of them Monday if anyone is interested.
