3M Precision Shaped Ceramic Grain Abrasive Disc Abrasive Disc, 127 mm, 120 Grade, 120 Grit

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal, scuffing and surface preparation across multiple substrates in industrial settings. It pairs with a vacuum-capable backing pad for dust extraction and attaches quickly using a hook-and-loop-compatible system. The construction combines a ceramic-shaped abrasive with aluminium oxide to deliver consistent cutting performance for finishing workflows in automation, electronics, electrical and mechanical environments.

• Precision shaped ceramic grain improves cut rate and life
• Net backing enables efficient dust extraction with vacuum
• Hookit-compatible attachment allows Rapid disc changes
• Resin pattern coating reduces loading and enhances finish
• Blend of ceramic and aluminium oxide balances aggressiveness and finish

• Suitable for paint and primer removal prior to rework
• Ideal for composite panel surface preparation in assembly
• Used for scuffing gelcoat and fillers before coating
• Can be used for intermediate sanding of whitewood components
• Suitable for metal surface stock removal in fabrication

A blend of aluminium oxide and 3M’s precision-shaped ceramic grain is resin-bonded to the net backing to provide both aggressive stock removal and controlled finishing behaviour.

Store in the 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 from heat or moisture exposure.

The open net backing is intended to be used with a supporting tool and a vacuum extraction system while the integrated loops mate with Hookit hook-and-loop pads for quick changes.

Maximum orbits per minute vary by disc diameter
