3M 7000028311 Hookit Sanding Block 70mm X 198mm

Product Description

The 3M 7000028311 is a Hookit dust-free sanding block designed for use with Hookit disc attachment systems in surface preparation and finishing applications. Measuring 70 millimeters by 198 millimeters, this block provides a firm, consistent backing surface that promotes even abrasive contact across the workpiece. At 0.69 pounds, it is lightweight enough for extended use. The dust-free design integrates with compatible vacuum or dust extraction systems to keep the work area clear and maintain visibility of the surface during sanding. It is sold as an individual unit.

This sanding block is suited for professional finishing and surface prep work in automotive bodywork, woodworking, and general fabrication environments. The Hookit attachment system allows for quick disc changes without adhesives, reducing downtime between grits. It is appropriate for use on flat or gently contoured surfaces where a rigid backing pad is preferred over a flexible one. Tradespeople and finishing technicians who rely on dust-managed sanding setups will find this block a practical fit in their workflow.
