sansheng 4 Pieces Concrete Grinding Wheel 4 inch,Diamond Cup Wheel Angle Grinder Wheels Grinding of Concrete, Granite

Cant beat this price and these things grind like beasts even when youre scraping down to the metal. Should have bought more

works great

I used these grinders to remove paint from a huge concrete surface. More than 50 yrs. and 4-5 layers of paint and mildew. Saved myself a lot of money. The picture posted is one small section completed. With patience the end result is phenomenal.

Used it to chew up exposed tree roots in my yard Ive bent many a mower blade on. Excellent,quick, durable,cheap!

Worked as hoped it would!

Works well, almost no wear after 30 minutes use on mortar, concrete, stone,

It went through three harbor freight angle grinders before I was done and it still has a lot of life left. Im glad the store is so close and they take returns.

Excellent product. I removed the paint from my concrete patio in short (but extremely dusty) order with little or no wear to the blades.

I form rocks for tumbling this works so well it is unbelievable

Did not expect to complete the work in a short time.
