3M abrasive sanding discs Hookit P280 150 mm, pack of 100 (MPN 7000034121)

Pack of 100 3M Hookit abrasive sanding discs in P280 grit with a 150 mm diameter, designed for fine sanding and finishing of wood, paint, filler and metal surfaces. The discs are made for use with Hookit backing pads on orbital and random-orbit sanders, providing consistent surface quality and quick disc changes thanks to the Hookit fastening system. The product suits both professional workshops and DIY projects requiring smooth, even finishes.

Advantages

These sanding discs feature a fine P280 grit that balances material removal and surface refinement, reducing visible scratches while preparing surfaces for final coats. The Hookit attachment enables fast replacement and stable mounting on compatible backing pads. Manufactured to deliver uniform abrasive performance across the disc, these abrasives maintain consistent cutting action and deliver predictable results across multiple substrates.

Suitable for

• Final sanding of wood before varnishing or staining
• Smoothing paint and filler prior to topcoat application
• Feathering edges and blending repaired areas
• Light finish sanding on metal to remove minor imperfections
• Orbital and random-orbit sanding tasks where a 150 mm disc is used

Key specifications

• Grit: P280 (fine)
• Diameter: 150 mm
• Backing system: Hookit (self-adhesive hook-and-loop style attachment)
• Quantity: 100 discs per pack
• Intended tool type: orbital and random-orbit sanders with compatible backing pad

How to use

Fit a compatible 150 mm Hookit backing pad to the orbital sander. Align the disc and press it firmly onto the backing pad so the Hookit connection engages across the surface. Start sanding with light to moderate pressure, keeping the sander moving to avoid gouging or uneven wear. For finishing passes, use slower feed and minimal pressure to achieve a uniform surface. Replace discs as abrasive performance declines to maintain consistent results.

Usage recommendations

Use appropriate personal protective equipment such as dust masks, eye protection and hearing protection. Match the P280 grit to the stage of preparation — use coarser grits for major material removal and P280 for final smoothing. Ensure the backing pad and sander are compatible and in good condition to avoid vibration and uneven sanding.
