El articulo resulto muy pequeño no como se veia en la foto.

Perfect size. Strong and durable. Can’t beat the price.

I have a cheap angle grinder but with this wheel I was able to smooth over a concrete crack repair job cutting down both new and old concrete with ease. Job well done.

So much better then the $35 each ones I’ve purchased in the past. Great value.

The embedded diamonds are spars and straite the concrete as you grind it. If youre just rough grinding, and dont need them to last very long, these work well enough.

Working well for a great price. Expected them to fall apart quickly, and they’re not. Using them to grind cracks in a basement floor. Pleased for the price!
