Electrocorundum abrasive material in the form of a full fill
Due to the very high hardness, strength and abrasion resistance, electrocorundum abrasive material is used in the QRC 411 Quick Change Disc mini discs with plastic thread attachment. The fill is full, so the disc base is almost 100% covered with abrasive crystals. This enables the removal of a large amount of material and guarantees high durability, and therefore a long product life. Quick Change Disc mini discs with plastic thread attachment are used for rough and intermediate grinding of metals, especially non-ferrous metals (e.g. brass, copper and aluminium, i.e. so-called non-ferrous metals). Klingspor offers the Quick Change QRC 412 mini discs in various diameters and grit sizes.

Robust abrasive discs thanks to synthetic resin bond
Intended for professional use, the QRC 411 discs with plastic thread attachment have a stable synthetic resin bond. This bond is characterised by excellent grinding ease and pleasantly low grinding pressure. The optimum properties are complemented by excellent grain adhesion and low heat development under heavy loads.

Optimum results with the right accessories
The Quick Change Disc mini discs with plastic thread attachment work together with the QRC 555 backing discs from Klingspor. They form the connection between the abrasive disc and the tool. Depending on the application, you can choose harder discs for high material removal or softer discs for greater flexibility, for example for grinding profiled parts. These discs are attached to the backing discs using the QRC system (Quick Roll Connect) by easily turning 180 degrees to the right. The high level of smoothness enables fatigue-free grinding and uniform results. With the matching QCA 555 mini disc adapter, the Quick Change Discs are also ideal for use on standard angle grinders. Their quick assembly significantly increases work efficiency.
