Lightweight Pad Helps Enhance Operator Comfort The lightweight, shock-resistant 3M™ Hookit™ Low Profile Disc Pad holds a 3M™ Hookit™ Disc (sold separately) on a random orbital sander or other rotary tool. Our Hookit™ system makes disc changes quick and easy and enables repeated use for the life of the disc, reducing material consumption. The disc pad has 5/16-24 external threads compatible with a random orbital sander or other tool with 5/16-24 internal threads. The one piece stud design improves balance and reduces vibration to enhance the quality of the finish and reduce operator fatigue. Quick, Easy Disc Attachment Whether you need 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 our 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 provide an efficient way to work through multi-step finishing processes and can be used again and again for the life of the abrasive.
