3M Precision Shaped Ceramic Grain Abrasive Disc Abrasive Disc, 127 mm, 150+ Grade, 150 Grit

3M Adhesive-Backed/PSA Sanding Disc, 127mm Disc Diameter, 150 Grit size - 7100288234

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general sanding, stock removal and surface preparation across multiple substrates. It combines a blend of aluminium oxide and precision-shaped ceramic grain to deliver consistent cutting and finishing performance when used with a compatible backing pad and extraction system. The hook-and-loop attachment Interface allows quick disc changes and the net construction facilitates dust removal when paired with a vacuum-equipped tool.

Features & Benefits

• Precision-shaped ceramic grain improves cut rate and longevity
  PSA attachment enables fast, secure pad changes
  Net backing permits effective dust extraction when vacuumed
  Pattern coating reduces loading and aids finish quality
  Resin bond ensures consistent abrasive distribution during use

Applications

• Suitable for scuffing and intermediate sanding of painted surfaces
  Ideal for prepping metal panels prior to welding or coating
  Used for abrading composite and gelcoat surfaces in fabrication
  Can be used for removing sealers, fillers and putties during repair
  Suitable for integration into automated sanding stations with extraction

What abrasive composition is used to balance cut and durability?

A mixed mineral formulation pairs aluminium oxide with 3M’s precision-shaped ceramic grain to maintain cutting efficiency while extending abrasive life.

How should discs be stored to maintain performance?

Keep them in their original packaging at 16°C to 26°C and 35 to 50% relative humidity on a first-in, first-out basis to minimise shelf degradation.

Which operating speeds are compatible with this product form?

The product family is designed for random orbital tools
safe maximum orbits vary by disc size and application and should match the tool manufacturer’s recommendations.

How does the net construction affect workplace cleanliness?

The open backing enables dust to pass through to a backing pad and vacuum system, reducing airborne particulates when extraction is used.

What attachment systems are supported for automated changeover?

The integrated loop Interface is compatible with Hookit-style hook-and-loop backing pads for Rapid automated or manual disc replacement.
