3M Precision Shaped Ceramic Grain Adhesive-Backed/PSA Sanding Disc Abrasive Disc, 76.2 mm, 220+ Grade, 220 Grit

This adhesive-backed/PSA sanding disc is designed for general-purpose sanding, stock removal and surface preparation across multiple substrates in industrial settings. It combines a blend of aluminium oxide and precision-shaped ceramic mineral on a net backing that allows dust extraction when used with a compatible backing pad and vacuum. The Hookit-style loop attachment integrated into the net enables Rapid disc changes without aligning extraction holes, making it suitable for continuous workflows in automation, electronics, electrical and mechanical environments.

• Precision-shaped ceramic grain delivers Faster cut rates and lower heat
• Net-backed construction enables efficient dust extraction with a vacuum
• Hookit loop integration permits quick tool-free disc replacement
• Patterned coating reduces loading and improves finish consistency
• Resin bond maintains abrasive integrity during aggressive sanding

• Suitable for de-nibbing filled surfaces in auto body repair
• Ideal for preparing painted panels prior to recoating
• Used for scuffing and blending composite components
• Can be used for metal deburring and light stock removal
• Suitable for sanding filler and putty on structural parts

The disc is mounted on an open net backing that pairs with a supporting tool and vacuum system to channel dust away from the work area during operation.

It is formulated for primer, paint, lacquer, sealer, fillers, putty, gelcoat, composite materials, whitewood and metals.

Keep in the original box at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis

Loops are integrated into the net backing to Interface with a Hookit-style hook-and-loop pad for simple, repeatable fitment.

The formulation is a blend of aluminium oxide together with a proprietary precision-shaped ceramic grain for combined cut and finish behaviour.
