LUKAS V4 PoMASTER wer universal lamellar flap disc Ø 178 mm zirconia alumina grain 40 dished

This extremely aggressive and durable flap disc with crescent flaps and zirconia alumina is the perfect alternative to grinding discs or conventional flap discs. It is ideally suited for rounding off sharp edges, machining weld seams or thermal cuts, e.g. in steel and container construction, in shipyards and offshore, or in mechanical and plant engineering. 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 additionally 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. Thanks to its 22.23 mm bore, this flap disc can be used with any commercially available angle grinder. Thanks to its flexibility, the lightweight, stable and elastic glass fabric carrier produces exceptional surface results. The high resistance to shredding and minimal vibration during operation, not to mention its easy handling, perfectly round off the characteristics of the lamellar flap disc. 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.
