I'm looking for recommendations for reasonably priced abrasive discs for my 100mm angle grinder. I recently threw out a wire wheel because I reckon it was dangerous. It would sometimes catch on edges and kick violently. It also threw off pieces of wire. Today I bought a Flex-O-Vit abrasive disc at Bunnings. While it worked very well it didn't last long. I used it to descale a 2m length of 40x5 flat steel. It was a quick job, but the disc was over half worn when I had finished. At $17 each that's not going to work. I also bought a Josco flap disc for $7. I suspect it will last longer, but it looks a lot more aggressive. What do you guys use?
