Thread: Grinding wheel dressers

Diamond cutting wheels for the 4" angle grinder are great wheel dressers... Buy 'em from the $2 shop. They make great, cheap dressers. They usually cost about $12 for a pack of two.

I find the carborundum sticks do a good job of cleaning the Al. Ox. wheels but leave them too smooth. To roughen them (for betting grinding) I use the diamond point dresser, and use it roughly. Even then, when you feel the wheel surface its clearly smoother than the untouched wheel side. Seems a star wheel is necessary.

Great tip, Chris. Wish I'd heard of it a couple of years ago before I bought the single point & the T bar dresser...


I think I read somewhere that the single point dresser leaves the wheel "sharper" than the T bar type, but to achieve this the s.p. dresser must be moved across the wheel at a steady, not too slow, rate so it's not rubbing on the just sharpened abrasive. Hence the idea, taken to a conclusion, of the flash tormek dresser that has a "lead screw" type design.

I've found the t bar easiest to use, but intend making a copy of the Oneway jig like Stu from Tokyo made, that allows very small adjustment. Still need to hand feed across the wheel surface, though.

Not quite the same but along the same lines.

I used to do contract work brazing the diamond tips on concrete cutting blades and I asked the boss man if I could have a bit for dressing, so he gave me a bit of diamond impregnated carbide about 10mm x 10mm x 25mm to which I silver soldered a bit of rod onto it for a handle and this is the bees knees, it rips into grinding wheels beautifully.
