For tough, hard-to-reach sanding and grinding applications, Mini Abrasive Belts work especially well with Mirka’s File Belt Sanders (pneumatic PBS and cordless FBS). Mirka’s Mini Abrasive Belts excel at roughing, cleaning, finishing, and polishing surfaces. The open design of the non-woven Surface Conditioning belts quickly cleans surfaces without damage and with virtually no heat build-up. Robust aluminum oxide grains and the three-dimensional structure lowers surface heat to preserve structure and color for an excellent finish quality. Choose Coarse or Medium grit.
