BradJohnson Posted November 12, 2012 Report Share Posted November 12, 2012 So, i'm fed up with my stupid cheap grinding discs giving me a gash grind on my rims. I'm currently using some disc's i got from B&Q not sure of the brand but they came in a pack of 10 for £10 when i get half way around one side of my rim the disc's are dead! Just wondering whats the best disc's to use in 115mm as i'm going to screw fix tomorrow morning to get some. I was looking at the makita ones/dewalt ones. Any thought's, opinions or past experiences would be great. Thanks very much! Quote Link to comment Share on other sites More sharing options...
Jake. Posted November 12, 2012 Report Share Posted November 12, 2012 Heard that stone cutting discs are best I think, but I'm not that clued up when it comes to grinds. Quote Link to comment Share on other sites More sharing options...

Yeah metal and stone cutting disc's are the same thing. well i pressume so everyone one i've seen say stainless steel and stone. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted November 12, 2012 Report Share Posted November 12, 2012 I used stainless steel cutting discs and they give a good grind. Different results for different people though depending on how good your technique is... Quote Link to comment Share on other sites More sharing options...
Dave Anscombe Posted November 12, 2012 Report Share Posted November 12, 2012 Never get a griding disc always a cutting disc! GET ONE THATS AROUND 3-5MM DEEP! Quote Link to comment Share on other sites More sharing options...

dann2707 Posted November 12, 2012 Report Share Posted November 12, 2012 Every quarter turn of the rim turn the grinder off and use a wire brush to remove built up alu from the disk, that's what's dulling your grind. 1 Quote Link to comment Share on other sites More sharing options...
N.Wood Posted November 12, 2012 Report Share Posted November 12, 2012 I use metal cutting, and grind it on a bit of rock every now and again to remove the alu thats built up. Also the nice square edges of the disk make a huge difference so change often. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted November 12, 2012 Report Share Posted November 12, 2012 Anything works well with the right technique. As Nick said, getting rid of the build up is a good idea too. 1 Quote Link to comment Share on other sites More sharing options...

ogre Posted November 13, 2012 Report Share Posted November 13, 2012 removing the alloy from the grinding disc is crucial TNN told me. and so did other posters.. the disc type doesn't make much difference, push hard into the grinder while you grind, move it quickly and always check you havent missed a big spot of sidewall...

customrider-Rhys Posted November 13, 2012 Report Share Posted November 13, 2012 diamond cutting discs are insane, preally sharp, best grind i ever did Quote Link to comment Share on other sites More sharing options...
ooo Posted November 15, 2012 Report Share Posted November 15, 2012 I like the 0.8mm ultra thin discs, they don't remove much metal and grinding takes much less time. http://www.toolstation.com/shop/Power%20Tool%20Accessories/Cutting%20Discs/Ultra%20Thin%20Disc/d80/sd1750/p39737 Although I think I would like the diamond cutting disc too, so may try that soon.

SamKidney Posted November 17, 2012 Report Share Posted November 17, 2012 (edited) I found that the diamond cutting discs would give a deep, harsh grind but the grind itself would be quite dull. I only tend to use one for the first grind of a new rim as it cuts through the anodising easier than a cutting disc.
