Durable, efficient, and easy to use. These STI metal grinding discs make concrete prep work so much faster. They hold up well under heavy use and don't wear out quickly. Highly recommend.

These metal bond diamond grinding tools have revolutionized my projects. They offer exceptional control and accuracy.

Aggressive grinding, save the time. I will use more on another job.

There is a reason that the professionals use these.They work great!

This has helped me tremendously. I had an uneven interface at two slabs that were down before we even moved in here, With this grinding cup it roughs up and cleans the surface nicely, I'm pretty sure I can get away with using this instead of acid-etching as I finish prepping for paint.
