TILAX Wire Wheel Brush Cup Brush, Twisted Knotted Cup Brush for Grinders, 5/8 Inch-11 Threaded Arbor, 0.020 Inch x 3 Inch for Heavy Cleaning Rust, Stripping and Abrasive, for Angle Grinder

Used this to clean surface rust off the replacement bed for my truck. I attached this to my 4 angle grinder and took the surface rust right off. Seriously heavy duty product.

Its so out of balance that when this thing spins in my angle grinder the entire tool vibrates so extremely that its hard to hold, much less control. Im not adverse to doing risky things but even this feels more dangerous than it ought to.

Awesome

These were terrible right out of the box. Rated for 12,509 rpm and pit them on my 12,000 rpm grinder. The vibration was so bad you couldnt even use them. I even tried the 2nd one just in case one was a lemon. Both were junk.

groovy

Works like it should much better than paying double for name brand

Very tight and heavy

everthings great

This product becomes unstable/out of balance once you start the grinder. I believe that the steel ropes spread out due to the centrifugal force thus causing the vibrations & unbalancing of the grinder. Might be better for low speed type of grinder units.

Does an adequate job for a hobbyist; no regrets on the purchase
