This super-flexible lamellar flap disc for machining hard-to-reach areas is the perfect alternative to grinding discs or conventional lamellar flap discs. It is perfect for deburring, fettling, derusting, smoothening and weld seam machining. The small resin core with the practical M14 thread enables an even larger flap projection (than with the SLT-flex). This makes the grinding disc extremely flexible, it can adapt itself to uneven surfaces, and requires little effort when working. With its long tool life, it is ideally suitable for fillet weld grinding. There is no risk of the workpiece being damaged by the carrier. Compared to grinding discs, the LUKAS patented flap shape and arrangement provides for 50% lower noise levels, less vibration, faster operation, greater efficiency and better surface results. The flat position of the optimally bonded flaps not only makes for safer working, but also cuts down the tool wear. The abrasive grain adheres particularly firmly to its backing and is optimally used. A particularly large concentration of abrasive grains on the outer perimeter results in an exceptionally high removal rate per minute. Excellent removal rates and an exceedingly long tool life are guaranteed. Thanks to its multi-layer abrasive coating, this lamellar flap disc stays just as sharp as at the first time of use. When the top flaps wear down, the fresh abrasive coating of the flaps underneath is exposed. In this way, they achieve a long service life and consistent working quality. Thanks to the self-sharpening effect of the zirconia alumina, combined with the extreme hardness and sharpness of the abrasive grain, this tool achieves high removal rates and a long service life, especially with hard and tough materials such as stainless steel. The abrasive grain of this flap disc is perfectly aligned by means of an abrasive surface layer and a special scattering process during the production. The tool does not become clogged, is sharper, requires little effort when working with it, and does not even cause blue discolouration or glazing. A high-quality resin system prevents this tool from rupturing at high speeds or working temperatures. Regular testing ensures a high degree of reliability. In addition, we pay attention to environmental conservation during the production and use start-of-the-art technologies with short curing times.
