Abrasive Disc 3M PS33BK 225 mm 220 grit pack of 50

3M PS33BK abrasive discs, 225 mm diameter with 220 grit, come in a pack of 50 and are designed for medium-fine sanding and surface preparation. These discs are suitable for use on metal, wood and painted surfaces when mounted on angle grinders or sanding systems that accept 225 mm discs. The balanced abrasive structure provides consistent material removal and a uniform finish across large areas, supporting workshop and professional applications where predictable sanding performance is required.

Advantages

The 220 grit abrasive provides a medium-fine cut that reduces visible scratch patterns while maintaining efficient stock removal. The discs are supplied in a bulk pack of 50, which supports continuous work without frequent reordering. Their 225 mm diameter fits common industrial and workshop grinders, and the abrasive composition is formulated to deliver stable performance on multiple substrates including metals, wood and paint layers.

Suitable for

• Removing minor surface imperfections and preparing metal for painting or welding
• Sanding and leveling wood prior to finishing
• Feathering and smoothing existing paintwork
• General-purpose workshop surface preparation with angle grinders or compatible sanding systems

Key specifications

• Diameter: 225 mm
• Abrasion grade: 220 grit (medium-fine)
• Quantity: pack of 50 discs
• Compatible with angle grinders and sanding systems accepting 225 mm discs
• Suitable substrates: metal, wood, painted surfaces

How to use

Attach the disc securely to a compatible 225 mm backing pad or flange following the grinder or sander manufacturer's instructions. Start sanding at a moderate speed and apply even, controlled pressure to avoid gouging; allow the abrasive to do the work. For painted surfaces, begin with light passes to assess compatibility and progressively increase pressure or passes to achieve the desired finish. Replace discs when abrasive efficiency declines or the disc becomes damaged.

Usage recommendations

Use appropriate personal protective equipment including eye protection, hearing protection and a dust mask or respirator when sanding. Match grit selection to the task: 220 grit is effective for medium-fine finishing and feathering but may be followed by finer grits for a smoother surface prior to painting or clear coating. Store discs flat in a dry environment to maintain performance.
