Concrete Diamond Turbo Grinding Cup Wheel,BRSCHNITT 115mm Angle Grinder Diamond Turbo Row Cutting Wheel for Grinding/Polishing/Cleaning Surface Grinding Granite,Concrete,Stone,Cement,Marble,Rock

Purchased to bring concrete path section, worked well

Great easy to use, very robust but could be over used if not careful

I used this to prepare a concrete garage floor to attach a waterproofing strip across the door. Polished the concrete really nicely, and rubbed down the embedded aggregate too. It does wear down quite quickly, so for a big job you may need more than one disc.

Excellent work and lasts

Worked well, could be more durable

Although this is designed to be used with an angle grinder I adapted it for use in a drill to use at lower speed to ‘plane’ the surface off concrete gate post pillar caps to prepare the surface for repairs. In an angle grinder I think it would have been difficult to control how much material would have been removed but this worked perfectly to leave the surface very flat and smooth.

I used this grinding cup in a dust shroud, which was definitely required, to remove a high point ridge across a door opening where we were continuing laying metre long floor tiles through from one room to the next. There was some self levelling compound to remove before I got down to the concrete base slab but this grinding cup in a 4.5” angle grinder and the necessary dust shroud attached to a dust vac did the job faultlessly. It worked like a dream. Whole job took about an hour but is now level and tiled.

Makes a good job of removing tile adhesive, but I had to remove angle grinder shield for it to fit, as it was catching on the shield.
