3M Precision Shaped Ceramic Grain Abrasive Disc Abrasive Disc, 203.2 mm, 220+ Grade, 220 Grit

3M Adhesive-Backed/PSA Sanding Disc, 203mm Disc Diameter, 220 Grit size - 7100287827

This adhesive-backed/PSA sanding disc is a net-backed abrasive designed for general-purpose sanding, stock removal, surface preparation and finish work across multiple substrates. It combines a blended mineral abrasive with a precision-shaped ceramic grain on a perforated backing to enable dust extraction when used with a compatible backing pad and vacuum system. The hook-and-loop-compatible attachment system allows Rapid disc changes on production lines and in workshops.

Features & Benefits

• Precision-shaped ceramic grain reduces loading and maintains cut
  Pattern-coated abrasive improves finish and extraction performance
  Net backing enables effective dust capture with vacuum systems
  Hook-and-loop compatible for fast, tool-free disc changes
  Blend of aluminium oxide and ceramic for sustained stock removal
  Designed for up to 6,000 opm for robust orbital sanding applications

Applications

• Suitable for bodywork sanding where dust extraction is required
  Ideal for scuffing and paint preparation on metal panels
  Can be used for intermediate sanding of composites and gelcoat
  Used for surface preparation prior to priming and painting
  Suitable for sanding tasks in automated finishing cells with vacuum extraction

What backing is used to aid dust control during sanding?

The product uses a net-style backing that allows airflow through the disc to a vacuum-connected backing pad, improving particle removal at the source.

Which abrasive minerals are combined in the coating?

The coating is a blend of aluminium oxide with a proprietary precision-shaped ceramic grain to balance cut rate and abrasive life.

How should the discs be stored to preserve performance?

Store in their original box at 16°C to 26°C and 35 to 50% relative humidity, using a first-in, first-out rotation to maintain shelf life.

How does the attachment system affect changeover speed?

Integrated loops in the backing pair with a hook-and-loop pad, enabling quick, repeatable disc swaps without aligning extraction holes.

What operating limitation should users note for high-speed sanders?

The disc construction is rated for typical orbital speeds up to 6,000 opm
users should match tool speed to this envelope for safe operation.
