3M Ceramic Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 76.2 mm, 120 Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general-purpose sanding, stock removal and surface preparation across multiple substrates in industrial settings. It pairs with a hook-and-loop backing system for Rapid disc changes and uses a hybrid abrasive blend to deliver controlled cut and finish while allowing dust extraction when used with a supporting tool and vacuum.

• Precision shaped ceramic grain for Faster cut rates and longevity
• Net backing enables efficient dust extraction with vacuum systems
• Hookit-compatible loops allow quick, tool-side disc changes
• Proprietary patterned coating reduces loading and improves finish
• Available in a range of grades to match process stages

• Suitable for scuffing and preparing primer and paint before repainting
• Ideal for removing filler, putty and surface sealers from components
• Can be used for finishing gelcoat and composite surfaces in production
• Suitable for intermediate sanding of whitewood and other timbers
• Used for abrading metal substrates prior to bonding or coating

A blend of aluminium oxide and a precision-shaped ceramic mineral delivers aggressive material removal with a balance between cut and life.

Store in the original box at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to minimise shelf-life reduction.

Maximum orbits per minute vary by disc diameter

The open net backing permits airborne debris to be drawn through the disc into a vacuum, reducing surface dust and improving extraction efficiency.

Alternative dimensions are available on request through make-to-order arrangements.
