Focus on the Task at Hand with Hookit™ Attachment

Whether you're using a random orbital or rotary sander, buffer, grinder, drill, finishing sander or other power tool, 3M™ Hookit™ products allow you to focus more on the task and less on tooling. Hookit™ abrasive products with hook-and-loop backing are manufactured with loop material that mates to a backup pad, each sold separately, where tiny hooks firmly engage the loops. Attachment is quick, easy, and secure during use. Sanding, finishing, and surface conditioning products with the 3M™ Hookit™ attachment and removal system give you an efficient way to work through multi-step finishing processes and can be used again and again for the life of the abrasive.
