Qing Yang® is a specialized 9 inch cutting wheel OEM manufacturer, supplying heavy-duty abrasive solutions to global hardware distributors. Designed specifically for large 9-inch (230mm) angle grinders, our 230×3.0x22.23mm metal cutting disc is engineered to withstand the extreme torque and pressure of heavy industrial applications, including shipbuilding, railway construction, and large-diameter pipeline fabrication.
Why Choose a 3.0mm Thickness for a 230mm Cutting Disc?
While many standard 9-inch discs are 1.9mm or 2.0mm thick for faster cutting, our 3.0mm profile offers distinct industrial advantages:
- Maximum Lateral Stability: Large angle grinders operate with significant gyroscopic force. The 3.0mm thickness resists bending and catastrophic lateral fracture under heavy manual pressure.
- Extended Lifespan: Engineered with high-density Aluminium Oxide, this disc provides a substantially higher cutting volume per wheel, reducing downtime for wheel changes during continuous weld preparation.
- Safety in Harsh Environments: Fortified with heavy-duty dual-fiberglass mesh, it safely operates at the critical 6,600 RPM (80 m/s) required by 230mm high-power angle grinders, exceeding European EN 12413 safety standards.
Comprehensive OEM & Private Label Abrasives Manufacturing
As a direct-to-market factory, we provide complete custom production for wholesale buyers looking to scale their own abrasive brands:
- Tailored Resin Bonds: We can adjust the resin-to-abrasive ratio. Need a softer bond for fast cutting on stainless steel (INOX), or a harder bond for maximum longevity on structural carbon steel? Our R&D handles it.
- Custom Branding: We print your exact logo, safety icons, and color schemes on the central blotter.
- B2B Packaging Solutions: From shrink-wrapped inner bundles to heavy-duty, moisture-resistant master cartons designed for FCL (Full Container Load) marine shipping.

Frequently Asked Questions (OEM & Wholesale)
ج: Our standard 9-inch (230mm) discs feature a 22.23mm (7/8 inch) arbor bore, complete with a reinforced steel ring. This is the universal standard for all professional large angle grinders globally, ensuring a secure, vibration-free fit.
ج: While a 3.0mm disc removes a slightly wider kerf than a 1.9mm disc, the trade-off is deliberate. For heavy industrial users, the 3.0mm thickness provides necessary safety against side-loading and offers a much longer lifespan, making it more cost-effective for heavy metal foundries than replacing thinner discs frequently.
ج: Because 9-inch discs use larger presses and molds, our MOQ for fully customized private label orders (including custom blotter printing and branded cartons) is typically 50,000 pieces. We can coordinate mixed-size container shipments to help you meet volume requirements.
ج: Yes. As a globally exporting OEM manufacturer, our cutting discs are rigorously tested and produced in compliance with MPA guidelines and the EN 12413 safety standard, ensuring they are fully compliant for distribution in Europe and other highly regulated markets.
