3M 068060-67222 Disc Hd-Dh Medium 150+ 7″ X Nh

This is a 7-inch diameter 3M Hookit disc designed for heavy-duty grinding and sanding on metals, fiberglass, and composites. It uses a durable, medium-grit abrasive (around 150+) on a strong backing that stands up to aggressive use. It’s useful because it removes material quickly and efficiently without tearing apart, which saves time and money on disc changes.

• Consistent Performance: The durable construction and abrasive material mean you get reliable cutting action from the first use to the last, reducing waste and ensuring uniform results on large jobs.
• Quick Attachment: The Hookit attachment system makes swapping out used discs for new ones very fast. This keeps your machine running and minimizes downtime during heavy work schedules.
• Versatile Application: While categorized as ‘medium’ grit, this disc is tough enough for initial material removal and preparing surfaces, making it a reliable option for various stages of metal fabrication or body repair.

Who this is best for

Fabrication shops, auto body repair professionals, and maintenance teams who need an aggressive, long-lasting disc for blending welds, heavy material removal, or preparing large surface areas on metal or fiberglass.
