4 Inch Concrete Stone Ceramic Turbo Diamond Grinding Cup Wheel,12 Segs Heavy Duty Angle Grinder Wheels for Angle Grinder (Yellow)

I used these wheels to grind down tileset after removing wall tiles, flew through the job, you need dust protection and a shroud cover as they generate a lot of dust, but excellent.

Used these to remove graffiti off brick walls,they did a great job,smooth operating and a good feel in operation,you have total control of takeoff and skimming,they are of good quality.

Good quality discs for price. Used to level areas of a cement floor and exposed block work. Will purchase again if needed.

Great item for the price. I used it to grind down the tops of some concrete pillars and it handled the job well, although it was only about 30 mins work so can't comment on how long it would last with regular use.

Functionality

Discs are not particularly hard wearing and the edge rounds over quickly. Fitting to grinder can be a problem as the centre depression where the spindle nut fits is too small a diameter for the flange of the nut. A washer has to used to fit the disc in place securely.

Used one of these to mend some pointing on front wall. They are good , robust and easy to attach. No problems encountered so far.

I didn't think they would be as good as they are, IMHO well worth the cost, no hesitation to recommend them!
