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. This product is mainly used for work on large surfaces.
