Zirconium Spirabands for Expanding Mandrels – Fast, Precise Internal Grinding
Spirabands (also known as drum sanding bands) are essential abrasives for grinding, shaping, and finishing internal surfaces, contours, and hard-to-reach areas. Designed to be used with rubber expanding drum mandrels on 6mm spindles, these bands offer aggressive material removal and smooth finishing—especially on stainless steel, mild steel, hard metals, wood, and composites.
Ideal for use with die grinders, rotary tools, and electric drills, our high-performance spirabands feature zirconium abrasive grain for long life, fast cut rates, and consistent results.
