The product was designed to deliver short set-up times and unrivalled effectiveness. The product is an excellent choice for professional users and keen do-it-yourselfers alike. Excellent removal rate thanks to close coating The QRC 411 relies on a self-sharpening zirconia grain and a close coating. This coating allows the abrasive to deliver a high removal rate and flawless results even when used for the most demanding jobs. The bonding is provided by a premium synthetic resin. This aggressive abrasive finishes the job exceedingly fast every time. An essential benefit of this product is that it lets the user achieve a uniform scratch pattern. Better still, it also allows the user to work over long periods with tiring. Secure connection via QRC The Quick Change Discs with plastic locking are designed for pairing with the QRC (Quick Roll Connect) system. The connection to the backing pad is established with an internal plastic threaded. One 180 degree clockwise rotation is all it takes to fasten the disc. This connection makes replacing the disc exceptionally comfortable and fast in real-world use. Users who need to combine the disc with a standard angle grinder will turn to the QCA 555, an adapter that was also engineered by Klingspor. Aside from Quick Change Discs for the QRC system, Klingspor offers products that go with the equally popular QMC (Quick Metal Connect) system.
