Machine suitability: This flap grinding disc (lamella disc) with cutouts is suitable for angle grinders of all power classes. Material suitability: The RHODIUS flap grinding disc VISION SPEED X-LOCK has been specifically developed for processing stainless steel (e.g., V2A, 1.4301), steel (black steel also known as construction steel, St37, S235JR, 1.0037 or carbon steel), and cast steel. The disc excels with a very high service life while maintaining aggressive material removal. Construction and manufacturing: The disc is manufactured according to EN 13743 and has been safety tested and is also oSa-certified. It features a fiberglass backing plate. The user can work with high pressure. The VISION SPEED X-LOCK uses high-quality ceramic grain (sintered corundum) as the abrasive grain, which is self-sharpening. All RHODIUS flap discs are also free from iron and sulfur. The flaps are arranged conically on this disc. The conical arrangement of the flaps at 12° improves ergonomics during grinding, making handling easier. Quality: With the VISION SPEED X-LOCK, the user receives the best RHODIUS tool in its category. RHODIUS TOPline products stand for the highest level of performance and quality. Application: The VISION SPEED X-LOCK impresses with a very high material removal rate. The special Top-Size coating of the flaps also ensures an even cooler grinding process. A unique feature is the three clever cutouts. The disc becomes transparent when rotating, allowing for continuous monitoring of the work progress without interruption. The user can see exactly what and how much they are grinding. Dimensions: The flap grinding disc is available in diameters of 115 mm and 125 mm, as well as with FEPA grits 40, 60, and 80.
