Polishing/Grinding Discs Michelin Expert P40, mesh with velour, 225 mm, pack of 5

Michelin Expert P40 polishing/grinding discs are 225 mm mesh-backed abrasives with a soft velour face sold in a pack of 5. They are developed for finish sanding, polishing and light material removal on a range of substrates including metals, wood and composite panels. The mesh construction improves dust extraction efficiency, while the velour backing provides a conformable contact surface for consistent finishes when used with 225 mm backing pads and compatible angle grinders or polishing tools.

Advantages

The mesh design allows effective dust extraction through the disc, reducing clogging and improving cutting consistency during prolonged use. The velour face offers gentle contact with the workpiece for smoother polishing and more controlled abrasion compared with rigid abrasive faces. The 225 mm diameter delivers broad coverage for faster work progress on larger surfaces, and the pack of 5 provides multiple replacements for uninterrupted tasks.

Suitable for

• Surface finishing and polishing of automotive panels
• Light sanding and blending on wood and veneered surfaces
• Removing light oxidation or preparing metal surfaces for painting
• Working on composite and fiberglass parts where dust extraction is required
• Use with 225 mm backing pads on angle grinders or rotary polishers

Key specifications

• Diameter: 225 mm
• Backing type: mesh with velour face
• Pack quantity: 5 discs
• Abrasion grade: medium (P40 - coarse for polishing/grinding tasks that require material removal)
• Compatible with 225 mm backing pads and standard angle grinders or polishing tools

How to use

Fit the disc onto a matching 225 mm backing pad and secure it according to the tool manufacturer’s instructions. Start the tool at low speed to confirm proper seating and balance, then increase to the recommended operating speed for the abrasive grade and material. Apply light, even pressure and move the tool continuously to avoid overheating or creating gouges. Use with a dust extraction system or vacuum when possible to take advantage of the mesh construction and maintain a cleaner working area.

Usage recommendations

For best results, select the Michelin Expert P40 when moderate material removal and polishing are both required. Maintain steady motion and moderate pressure, replace discs when wear reduces performance, and pair with an appropriate dust extraction setup to prolong disc life and improve working conditions.
