3M Ceramic Abrasive Disc Abrasive Disc, 127 mm, 500+ Grade, 50 Grit

3M Adhesive-Backed/PSA Sanding Disc, 127mm Disc Diameter, 500 Grit size - 7100335096

This adhesive-backed/PSA sanding disc is a 127mm, 500+ grade abrasive designed for industrial surface preparation and finishing. It pairs a C-weight paper backing with precision-shaped grain to deliver consistent material removal and is intended for use where dust control and throughput are important in automation, electronics, electrical and mechanical environments.

Features & Benefits

• Precision-shaped grain cuts up to 2x Faster and stays cooler
  Anti-load coating reduces clogging and maintains cut rate
  Multi-hole Xtract pattern improves dust extraction efficiency
  Hookit™ PSA attachment enables quick disc changes
  C-paper backing balances flexibility with dimensional stability

Applications

• Suitable for metal finishing and deburring in automated cells
  Ideal for scuffing and prep prior to topcoat application
  Used for coating removal and refinishing in bodyshop workflows
  Can be used for edge rounding and de-flashing on components
  Suitable for sanding composites, gelcoat and various woods

How does the disc assist with dust management during sanding?

The proprietary multi-hole Xtract pattern combined with the disc’s anti-load treatment promotes efficient dust evacuation when connected to extraction systems, reducing clogging on the abrasive surface.

What attachment method is used and how does it affect changeover time?

A Hookit™ PSA attachment provides adhesive-backed mounting that allows Rapid on/off changes and aligns easily with multi-hole back-up pads to speed operator changeovers.

Which substrates is this abrasive suited to in electrical and mechanical work?

The abrasive mineral and backing are applicable to metals, painted surfaces, composites, gelcoat and different woods, enabling use across component finishing and repair tasks.

How does the abrasive maintain consistent surface finish across discs?

The precision-shaped grain is microreplicated to form consistent cutting peaks and is coated evenly on the backing, resulting in comparable finish and fewer rogue scratches from disc to disc.
