3M Scotch-Brite Precision Surface Conditioning Disc Series Abrasive Disc, 125mm Disc Diameter, 8 Grit size - 7100274226

This abrasive disc is a precision surface conditioning tool designed for controlled material removal and finishing on metal substrates in industrial settings. It combines ceramic abrasive grain with a resin bond on a non‑woven backing to deliver aggressive cutting and consistent surface conditioning for fabrication and maintenance tasks in automation, electronics, electrical and mechanical environments.

Features & Benefits

• Ceramic resin bond for high material removal rate
  Precision‑shaped grain for Faster cut and extended life
  Non‑woven construction limits geometry alteration during use
  22.23mm bore compatibility for common machine spindles
  Extra coarse 8 grit for Rapid stock removal on steel

Applications

• Suitable for descaling and preparation of stainless steel weld seams
  Ideal for surface cleaning on carbon steel components
  Used for light stock removal on aluminium assemblies
  Can be used for finishing prior to electrical contact installation
  Suitable for integration with automated surface‑conditioning stations

What mounting options are compatible with this disc?

It fits 22.23mm bore holders and is designed for hook‑and‑loop and Roloc™‑style attachments commonly used in handheld and machine‑mounted assemblies.

How does it behave on thin gauge materials?

The non‑woven web minimises gouging and dimension change, making it appropriate for low‑pressure finishing on thinner metals when operated with controlled feed.

What is supplied per package and how does that affect workflow?

The product is sold in packs of 25, enabling reduced changeovers and easier inventory management for production lines.

Which substrates achieve the best throughput with this abrasive?

High throughput is observed on stainless steel and carbon steel where the ceramic grain and resin bond provide Rapid removal without undercutting.
