3M 1187C Precision Shaped Ceramic Grain Grinding Disc, 50.8 mm, 36+ Grit 50

3M Cubitron 3 Series Fibre Disc, 50.8mm Disc Diameter, 36 Grit size - 7100331754

This Fibre disc is a high-speed abrasive designed for material removal and surface preparation in industrial settings. It combines a precision-shaped ceramic abrasive with a robust Fibre backing to deliver Rapid cutting performance while reducing operator force. The disc fits quick-change attachment systems and is suited to applications where controlled heat generation and consistent wear are important.

Features & Benefits

• Precision-shaped ceramic grain reduces cutting pressure and increases throughput
  Grinding aid lowers grinding temperatures on heat-sensitive alloys
  Stiff Fibre backing resists tearing during heavy stock removal
  Strong resin bond extends disc life under variable pressure
  Quick-change attachment enables fast disc swaps and less downtime

Applications

• Suitable for weld removal on stainless steel components
  Ideal for bevel preparation in robotic grinding cells
  Used for medium-pressure surface grinding on aluminium assemblies
  Can be used for blending and finishing in electrical cabinet fabrication
  Suitable for deburring machined parts in mechanical workshops

What attachment method allows Rapid disc changes?

A roloc-style quick-attachment system permits fast swaps between grades and reduces changeover time during production runs.

How does the abrasive affect heat-sensitive metals?

An integrated grinding aid moderates cutting temperatures, helping to reduce metal discolouration and the risk of stress cracks on alloys such as stainless steel.

What backing and bond characteristics support heavy-duty use?

The disc uses a stiff Fibre backing paired with a strong resin bond to provide durability and tear resistance for demanding grinding and bevel applications.

How does the abrasive maintain cutting performance over time?

The precision-shaped ceramic geometry preserves Sharp cutting points during wear, delivering consistent material removal across the disc lifespan.
