How do I choose the right bond hardness for diamond tooling?

Use soft bonds on hard, dense concrete (high PSI) and hard bonds on soft or porous concrete. For most commercial floors, a medium bond is the safest starting point. Call us at (802) 489-0828 and we'll spec the right bond for your specific floor condition and machine.

Are these diamond tools compatible with my grinder?

US Abrasives stocks tooling compatible with all major grinder brands including Klindex, Lavina, Husqvarna, Superabrasive, STI Prep/Master, HTC, Blastrac, Diamatic, and Onyx. Tell us your machine model and we'll confirm fit before you order.

How fast does my order ship?

In-stock orders placed before 2 PM CST ship same day Monday through Friday via FedEx or UPS Ground. Most U.S. deliveries arrive within 2–5 business days. Expedited shipping is available — call (802) 489-0828 for a quote.

What diamond grit should I start with on a concrete floor?

For most concrete grinding and prep work, start with 16–30 grit metal bond diamonds to open the floor and remove coatings or adhesive. Then progress through 40–60 grit, transition to resin bonds at 100–200 grit for honing, and finish with 400–3000 grit resin pads for polishing. Your starting grit depends on floor hardness and what you're removing.

What tools remove epoxy coatings or glue from concrete?

PCD (polycrystalline diamond) scrapers and hard-bond diamond cup wheels are most effective for removing thick epoxy coatings and adhesive residue from concrete. For thinner coatings, soft-bond metal diamonds work well. We can spec the right tool for your coating type and thickness.
