Qing Yang® supplies industrial 4 inch cutting wheels built for real-world metalwork, not just catalogue specs. This page covers the 4 inch family as a whole, including 100mm, 105mm and 107mm discs, so distributors can compare the sizes that matter most in their market instead of browsing isolated product pages. If you need a dependable cut off disc for grinder use, this is the right place to start.
4 Inch Cutting Wheel Options for Different Market
A 4 inch cutting wheel is small enough to stay agile on handheld grinders, but the differences between 100mm, 105mm and 107mm are still meaningful in daily work. The 100mm version is the standard choice for broad-market supply, while 105mm adds a little more cutting depth and longer wear life. The 107mm option is often selected when buyers want a more specialized feel, especially for tighter fabrication work and thinner cutting profiles.
Built for Metal, Stainless Steel and Mixed Fabrication Jobs
Our 4 inch cut off discs are designed for carbon steel, stainless steel, alloy steel and general fabrication work. The abrasive blend is tuned to cut steadily without burning the workpiece or slowing down under pressure, which matters when customers are working on pipe, plate, rebar or maintenance jobs. For stainless steel buyers, the value is simple: a cleaner cut with less rework at the edge.
OEM Cut Off Disc Supply for Grinder Users
As a direct cutting wheel manufacturer, we support OEM and ODM orders with private label packaging, disc marking and size-based product positioning. That means you can build one 4 inch family with different sub-SKUs for different regions instead of forcing every market into one universal disc. We also keep the technical side practical: double fiberglass reinforcement, vacuum forming, standard 16mm bore and EN 12413 compliance are all part of the base offer.
Technical Strength That Matters
The 4 inch cutting wheel range is built around consistent run-out control, stable cutting speed and predictable wear. A dual fiberglass reinforced structure helps the disc stay safe at high peripheral speed, while vacuum-formed construction supports a flatter, more balanced wheel. In practice, that means smoother cutting feedback, less wobble on the grinder and a better result when the operator is working through steel or stainless steel in quantity.
Why Buyers Keep Reordering This Size
For distributors, the 4 inch category works because it sits right in the middle of portability and performance. It is small enough to fit the most common angle grinders, but strong enough to handle real metal cutting work in workshops, maintenance teams and construction supply chains. If you are building a stable abrasive wheel line, this is usually the size that gives you the widest repeat demand.

Preguntas frecuentes
The 100mm disc is the most universal option for standard supply, the 105mm disc gives a little more cutting depth and wear life, and the 107mm disc is often chosen when buyers want a more specialized cutting feel for certain fabrication jobs. All three belong to the same 4 inch family, but they serve slightly different market preferences.
These discs are best for carbon steel, stainless steel, alloy steel, pipe, plate and rebar. For stainless steel, the right abrasive balance helps reduce heat and edge discoloration, while for general steel the focus is faster cut speed and stable wear.
Yes. We support private label branding, custom cartons, disc labels and regional packaging layouts. That makes it easier to launch a 4 inch family under your own brand without changing the core product structure.
The range is built around EN 12413 and ISO 603 requirements, with dual fiberglass reinforcement and standard 16mm bore compatibility for common 4 inch angle grinders.
