3M Ceramic Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 203.2 mm, 320+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal, scuffing and surface preparation across a range of substrates. It combines a blend of aluminium oxide and a proprietary precision-shaped ceramic mineral to deliver consistent cutting and finishing performance when paired with a suitable Hookit™ backing pad and vacuum-assisted extraction.

• Precision-shaped ceramic grain delivers Faster cut rates
• Net backing enables effective dust extraction during sanding
• Patterned resin coating reduces loading for prolonged use
• Hookit™ loop integration allows Rapid tool-free disc changes
• Suitable for a wide range of substrates including paints and composites

• Suitable for automotive sanding on primers and paintwork
• Ideal for composite surface preparation in manufacturing
• Can be used for preparing filler and putty prior to finishing
• Used with vacuum systems for dust-controlled workshop operations

It uses a blend of aluminium oxide and a proprietary precision-shaped ceramic grain for a balance of stock removal and finish.

The open net structure permits vacuum extraction through the disc when used with a compatible support pad and dust collection system.

Loops are integrated into the net backing to mate with a Hookit™ hook-and-loop support pad for secure attachment and quick swaps.

Store in the original packaging at about 16 to 26°C and 35 to 50% relative humidity, using a first-in, first-out system to avoid shortened shelf life.

Maximum orbital speeds vary by disc size
