The Klingspor QRC 411 Quick Change Disc is built for fast, efficient grinding and finishing on stainless steel and other metal surfaces. Featuring a self-sharpening zirconia grain and a close-coated design, it delivers aggressive cutting power with a consistently high removal rate. The result is a clean, even finish with less effort and reduced operator fatigue.

Engineered for performance and convenience, the QRC 411 uses Klingspor’s Quick Roll Connect system, allowing discs to be attached or replaced with a simple 180° twist. This quick-change mechanism significantly cuts down setup time and ensures a secure fit during operation. A premium synthetic resin bond provides durability under heavy use, while the disc maintains a uniform scratch pattern even on demanding jobs.

Ideal for both professional fabricators and workshop environments, this 50mm disc performs exceptionally well in metal preparation, weld removal, and general finishing applications. It can also be paired with the Klingspor QCA 555 adapter for compatibility with standard angle grinders.
