POLINOX® unmounted flap wheels are made of non-woven polyamide abrasive, into which abrasive grain is integrated. The non-woven abrasive material is arranged in multiple radial flaps, with abrasive cloth interlayers. This flap structure improves stock removal and achieves a coarser surface finish. The product is designed for working on medium-sized surfaces with speed-adjustable angle grinders and fillet weld grinders, and can be mounted directly onto the drive system's spindle without the need for additional clamping devices.
