3M 1187C Precision Shaped Ceramic Grain Grinding Disc, 125 mm, 60+ Grit 25

3M Cubitron 3 Series Fibre Disc, 125mm Disc Diameter, 60 Grit - 7100349581

This Fibre disc is an abrasive wheel engineered for heavy material removal in industrial metalworking and fabrication environments. It uses a precision-shaped ceramic abrasive designed to maintain cutting sharpness and reduce heat generation during sustained grinding. The product is supplied in packs for repetitive tasks and is intended for use on grinders where controlled, high-rate material removal and predictable wear are required.

Features & Benefits

• Precision-shaped ceramic grit delivers Faster initial cut rate
  Grinding aid reduces pressure required and heat transfer
  Stiff Fibre backing resists tear under medium to high pressure
  Strong resin bond prolongs operational life during weld removal
  Designed for predictable wear to reduce changeovers

Applications

• Suitable for bevel preparation and weld removal on stainless steel
  Ideal for robotic grinding operations in production lines
  Used for heavy-duty material removal on non-ferrous alloys
  Can be used with angle grinders for component deburring
  Suitable for high-throughput metal finishing in automation

What hole size does it require for mounting?

It fits a 22mm centre hole for direct mounting on compatible back-up pads.

How should it be selected for heat-sensitive alloys?

Choose this disc for heat-sensitive metals because its abrasive and grinding aid lower metal discolouration and reduce the risk of stress cracking.

What packaging quantity is provided for continuous operations?

It is supplied in packs of 25 to support frequent disc changeovers in industrial settings.

What is the maximum permitted rotational speed?

The disc is rated to a maximum safe speed of 250 r/min for the specified diameter.

What backing material supports durability during high-pressure use?

A Fibre backing combined with a robust resin bond offers tear resistance for sustained grinding.
