3M™ Hookit™ Blue Abrasive Discs 36172 are a cost-effective, high-performance upgrade for coarse-grade sanding jobs in collision repair and other industrial work. The multi-hole pattern provides excellent dust extraction to help reduce loading and help extend disc life, while the universal design aligns with most sanders and backup pads for durable, long-lasting use. Quickly change discs with the Hookit™ attachment system – a hook-and-loop feature which helps make disc attachment, removal, and re-attachment clean and easy. The engineered ceramic mineral blend delivers strong abrasive performance in its class, and the anti-loading coating helps keep dust from gathering between the abrasive grains for a faster precision cut. 3M™ Hookit™ Blue Abrasive Discs 36172 deliver best-in-class cut, life, and efficiency across your entire shop.
