Qing Yang® is a dedicated 4 inch cut off wheel manufacturer specializing in industrial-grade 107mm (approx. 4.2 inch) abrasive solutions. Unlike standard off-the-shelf products, this SKU is built around flexible OEM manufacturing. We offer this 107mm cutting disc with variable thickness options—including an ultra-thin 0.8mm profile for precision work and a 1.2mm profile for general fabrication—allowing wholesale buyers to build a custom abrasive catalog that meets precise regional demands while complying with global ISO 603 standards.
Why partner with us for custom 107mm cutting wheels?
Variable thickness for different markets
As a direct manufacturer, we adapt the disc profile to your target audience. Choose the 0.8mm thin cutting disc option to minimize material loss and heat generation on stainless steel tubes, or select the 1.2mm thickness for a robust balance of cutting speed and lateral strength during heavy-duty steel structure repair.
Advanced vacuum forming technology
Our production line utilizes vacuum forming technology to ensure the aluminum oxide abrasive matrix is completely uniform. This process significantly improves the surface flatness of the metal cutting disc, reducing vibration during 14,500 RPM operations and ensuring consistent kerf widths across large production batches.
Complete private label OEM program
We provide end-to-end customization for B2B importers. This includes adjusting technical parameters within a ±5% tolerance to match specific market applications, offering industry-standard resin color systems (e.g., yellow, blue, or gray), applying laser-engraved or ink-printed brand logos, and designing custom retail packaging such as blister packs or branded color boxes.
Where our 107mm cutting discs perform best
Automotive and chassis repair
The 107mm metal cutting wheel provides the perfect diameter-to-clearance ratio for automotive mechanics cutting rusted bolts, exhaust mounts, and chassis components in tight spaces, especially when utilizing the 0.8mm ultra-thin profile.
Pipeline engineering
For hydraulic and HVAC contractors, this cutting wheel for grinders delivers precise, burr-free cuts on thin-walled stainless and carbon steel pipes (under 6mm wall thickness), minimizing the need for secondary edge grinding before welding.
General construction and rebar
When configured in the 1.2mm thickness, the disc meets EN 12413 safety standards for construction sites, offering fast and stable cutting of concrete reinforcing steel (rebar) and light structural frameworks.
Engineered for standard 4 inch grinders
Our 107mm cut off wheels feature a standard 16mm (5/8″) arbor hole, ensuring seamless compatibility with mainstream 4 inch angle grinders globally. The slightly oversized 107mm diameter (often referred to as 4.2 inches) fits comfortably within standard safety guards while offering additional cutting depth. Every disc utilizes a double fiberglass reinforced structure, providing the necessary burst resistance to safely sustain an 80 m/s peripheral speed.

Часто задаваемые вопросы
The choice of thickness depends on your market’s primary application. The 0.8mm ultra-thin option is highly specialized for precision tasks; it produces a very narrow kerf with minimal material loss and heat generation, making it ideal for thin-walled stainless steel tubes and delicate fabrication. The 1.2mm option is slightly thicker, offering greater lateral strength and a longer lifespan, which makes it the preferred choice for general construction, heavy-duty structural steel, and everyday metalworking tasks.
A 107mm outer diameter (often referred to as 4.2 inches) provides a practical middle ground for 4 inch angle grinder users. It fits perfectly within the standard safety guards of any 100mm tool but offers 7mm of additional abrasive material. This extra diameter translates to slightly deeper cutting capacity and fewer wheel changes during long shifts, which is a major selling point for industrial operators working with solid pipes or thick structural steel.
Yes, as a professional cutting disc manufacturer, we engineer all our abrasive products to meet strict global safety requirements. Our 107mm cut off wheels are manufactured in compliance with ISO 603 and EN 12413 standards. They feature a double-layer fiberglass reinforcement structure, allowing them to operate safely at a maximum peripheral speed of 80 m/s and 14,500 RPM under demanding industrial conditions.
We offer end-to-end customization for B2B importers looking to build their own abrasive brand. You can customize the physical product by selecting the disc thickness (0.8mm or 1.2mm) and resin color (such as green, black, or red). For branding, we provide custom label design, laser engraving or ink printing on the disc ring, and tailored retail packaging options—including blister packs, plastic drums, or branded master cartons—ready for direct distribution in your local market.
