3M 1187C Precision Shaped Ceramic Grain Grinding Disc, 180 mm, 80+ Grit 25

3M 3M Cubitron 3 Series Fibre Disc, 180mm Disc Diameter, 80 Grit - 7100349663

This Fibre disc is an abrasive tool designed for heavy metal removal and surface preparation in industrial environments. It uses a ceramic-based abrasive formulation fixed to a stiff Fibre backing, engineered for continuous grinding tasks and compatible with common production and robotic workflows. The disc is intended for use where predictable wear, controlled heat generation and sustained material removal are required.

Features & Benefits

• Re-engineered precision-shaped ceramic grain delivers Faster cutting rates
  Grinding aid reduces pressure required and limits heat transfer
  Stiff Fibre backing provides durability and resists tearing
  Maintains Sharp cutting points for extended working life
  Designed for medium to high-pressure weld removal and bevelling

Applications

• Suitable for robotic weld removal and bevelling operations
  Ideal for stainless steel and other heat-sensitive alloys
  Used for heavy stock removal in mechanical fabrication
  Suitable for surface preparation prior to finishing or coating
  Used with fixed and portable grinders in automation cells

What is the recommended maximum rotational speed for safe use?

The disc is rated for a maximum safe speed of 500 r/min, and operating above this speed should be avoided.

How is heat management addressed during prolonged grinding?

The abrasive includes a grinding aid that helps the disc run cooler, reducing metal discolouration and the risk of stress cracking on heat-sensitive metals.

What pack sizes are available for workshop stocking?

The product is supplied as a 25-pack intended for bulk use and reduced changeovers.

What backing and hole specifications facilitate mounting on common flanges?

The Fibre backing offers rigidity for medium to heavy-duty use and the centre hole measures 22mm to match standard mounting systems.

How does the abrasive perform across varying application pressures?

The shaped ceramic mineral continues to form new Sharp points, enabling consistent cut rates across a range of pressures and delivering sustained material removal.
