Feature:
1.Practical – 240 grit commonest and standard size sanding bands use for smoothing surface and curved edges, polishing both soft and hard materials, like home improvement, artwork and woodworks
2.Easy installation – drum mandrels with self-expanding rubber cushion, making the sanding bands close to the manderl firmly and acheiving better finishing; in case the sanding band fall apart from the mandrel while using, please make sure the drum have been screwed tightly and wear closely to the sleeve.
