3M 7000028312 Hookit Dust-free Sanding Block

Product Description

The 3M 7000028312 is a Hookit dust-free sanding block designed for flat and contoured sanding applications in automotive body, woodworking, and general finishing work. The block measures 70 millimeters by 396 millimeters and is engineered to accept Hookit disc and sheet abrasives, securing them firmly to the face of the block without adhesives. Dust-free construction channels sanding debris away from the work surface, reducing loading on the abrasive and improving visibility of the workpiece. At 1.67 pounds, the block is substantial enough for controlled pressure sanding while remaining manageable over extended use.

This sanding block is suited for body shops, finishing shops, and production sanding environments where flat panel work and long-board sanding are common. The elongated 396-millimeter length makes it appropriate for leveling primer, surfacer, and filler on large flat panels. Trade painters, auto body technicians, and finishing carpenters are the primary installers and users of this tool.

Key Features

• Hookit attachment system secures abrasive sheets without adhesives for fast changes
• Dust-free design channels debris away from the work surface to reduce abrasive loading
• 70 mm x 396 mm face provides extended contact length for leveling large panels
• Rigid block construction maintains consistent pressure across the sanding face
• Compatible with 3M Hookit abrasive sheets and rolls designed for this block width

Compatibility

Designed for use with 3M Hookit abrasive sheets and finishing films sized to fit a 70-millimeter by 396-millimeter sanding block face.

Installation Notes

Attach the appropriate Hookit abrasive sheet by aligning it to the block face and pressing firmly to engage the fastening system. Ensure the abrasive is seated flat with no lifted edges before applying pressure to the workpiece. Replace the abrasive sheet when cutting action diminishes or loading is visible. No power source is required; the block is a hand-tool accessory.
