3M 1182C 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 - 7100332086

This Fibre disc is a purple, Fibre-backed abrasive designed for industrial metalworking and surface preparation on high-speed rotary tools. It uses precision-shaped ceramic grain to deliver aggressive cutting while reducing operator effort, and it is intended for applications where predictable wear, reduced metal discolouration and efficient material removal are required.

Features & Benefits

• Precision-shaped ceramic grain reduces operator pressure while cutting
  Stiff Fibre backing offers tear resistance during heavy grinding
  Strong resin bond prolongs disc life under medium-pressure use
  Maintains Sharp points for consistent cutting throughout life
  Compatible with quick Roloc attachment for fast disc changes
  Rated maximum safe speed 15,000 r/min for high-RPM operations

Applications

• Suitable for weld removal on mild and carbon steels
  Ideal for bevel preparation prior to assembly
  Used for robotic grinding operations in automated cells
  Can be used for surface blending and profile finishing
  Suitable for medium-pressure surface preparation in workshops

What hole size is required for mounting on a quick-attach system?

The disc has a 22mm centre hole to fit compatible quick-attach spindles and Roloc-style adaptors.

How is heat generation managed during extended use?

The abrasive’s geometry requires less applied pressure, which helps reduce frictional heat and lowers the risk of metal discolouration and stress cracking.

In what packaging quantity is this disc supplied for bulk operations?

The discs are packaged in quantities of 50 per carton to support high-volume industrial use.

Which abrasive type is used and what does it offer for metalworking?

A precision-shaped ceramic grain is employed to sustain Sharp cutting points and deliver Faster material removal across varied pressures.
