3M Precision Shaped Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 203.2 mm, 150+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is designed for general-purpose abrading, stock removal and surface preparation across multiple substrates in industrial settings. It combines a patterned precision abrasive coating on a net backing to enable effective dust extraction when used with a compatible support pad and vacuum system, and attaches quickly via a Hookit-style hook-and-loop Interface for Rapid changeovers.

• Precision Shaped Grain mix delivers aggressive cutting and consistent finish
• Net backing enables extraction when paired with vacuum systems
• Patterned resin coating reduces loading and maintains cut rate
• Integrated loops provide fast hook-and-loop attachment
• Suitable for sustained use at specified maximum orbits

• Suitable for primer and paint surface preparation in bodyshops
• Ideal for removing fillers and putties from composite panels
• Can be used for scuffing gelcoat on marine components
• Used for intermediate sanding on wooden and painted assemblies
• Suitable for abrasive operations on various metals in workshops

It uses a blend of aluminium oxide and a ceramic Precision Shaped Grain mineral to balance Rapid material removal with surface finish control.

Store in their original box at 16°C to 26°C and 35 to 50% relative humidity on a first-in to first-out basis to avoid shortened shelf life.

Maximum orbital speeds vary by disc size

Discs mount using a hook-and-loop attachment integrated into the net backing and require a compatible Hookit-style backing pad.
