Diamond Grinding Cup Wheels for Concrete & Stone
Product Overview
SourcingProChina is a sourcing agent based in China, specializing in connecting overseas buyers with vetted manufacturers of diamond grinding cup wheels. Through our factory network, we source both sintered and brazed cup wheels designed for angle grinders and small floor grinders — suitable for leveling, coating removal, and edge work. We handle supplier screening, factory audits, quality inspection, and order consolidation, so buyers receive consistent product quality without needing to manage multiple factory relationships directly.

Core Advantages
- Verified Factory Sourcing: SourcingProChina pre-screens partner factories for production capability and quality control before recommending them to buyers, reducing sourcing risk for first-time importers.
- Two Manufacturing Methods Available: We can source either sintered (cost-effective, longer service life) or brazed (more aggressive cut, better for hard materials) cup wheels based on the buyer's application needs.
- Wide Selection of Shapes: From single-row to double-row, turbo, and arrow segments — our sourcing network covers multiple segment designs for different grinding applications.
- Universal Fit: Standard bore sizes (22.23mm, 25.4mm) sourced to fit most angle grinders and floor grinding machines on the market.
- Quality Inspection Support: We can arrange pre-shipment inspection (PSI) to check dimensions, bore size accuracy, and segment bonding quality before goods leave the factory.
Application Scenarios
- Edge grinding and leveling of concrete floors.
- Removing old epoxy, paint, and adhesive coatings.
- Grinding and shaping terrazzo, marble, and granite.
- Spot repair and surface preparation for small areas.
Frequently Asked Questions (FAQs)
What is the difference between a sintered and a brazed cup wheel?
A sintered cup wheel has diamond segments embedded into the metal matrix, making it durable and long-lasting. A brazed cup wheel has diamonds welded onto the surface, offering a more aggressive cut and better performance on hard materials. SourcingProChina can help you identify which factories specialize in each type based on your target application.
Can I use a cup wheel on a standard angle grinder?
Yes. These cup wheels are manufactured with standard arbor sizes (22.23mm) to fit most common angle grinders. We recommend confirming your grinder's specifications before placing a bulk order — our team can help cross-check compatibility with the factory before production.
Which grit size should I choose?
Choose a coarse grit (16#, 30#) for aggressive material removal and leveling. Use a finer grit (50#, 80#, 120#) for smoothing and finishing. If you're unsure which grit fits your project, SourcingProChina can request factory samples for testing before committing to a bulk order.
Can these be used for wet grinding?
Yes, both sintered and brazed cup wheels can be used for wet or dry grinding. Wet grinding is generally recommended to reduce dust and extend wheel life.
What is the maximum RPM for these wheels?
Maximum RPM varies by wheel diameter and factory specification; buyers should confirm the RPM rating on the specific product label before use. SourcingProChina can request this documentation directly from the manufacturer as part of the sourcing process.
