3M 1187C Precision Shaped Ceramic Grain Grinding Disc, 100 mm, 60+ Grit 25

3M Cubitron 3 Series Fibre Disc, 100mm Diameter, 60 Grit - 7100349572

This Fibre disc is a 100mm abrasive product designed for demanding metalworking and industrial grinding tasks. It blends precision-shaped ceramic abrasive technology with a robust Fibre backing to deliver consistent material removal in automated and manual operations. The disc is supplied in packs suited to production environments and is aimed at reducing cycle times while maintaining predictable wear.

Features & Benefits

• Precision-shaped ceramic grain improves cut rate and longevity
  Grinding aid reduces pressure and heat generation
  Stiff Fibre backing enhances durability under load
  Maintains Sharp cutting points throughout life
  High permissible rotational speed supports Rapid operations
  Orange colour for easy Visual identification

Applications

• Suitable for weld removal and bead blending on stainless steel
  Ideal for bevel preparation on heat-sensitive alloys
  Used for medium to high-pressure grinding in robotic cells
  Can be used for surface finishing on non-ferrous components
  Suitable for production-line deburring and stock removal

What is the centre hole size and why does it matter for mounting?

The centre hole is 16mm which ensures secure attachment to compatible backing pads and reduces runout for spindle-mounted use.

How does the abrasive formulation affect workpiece temperature?

The re-engineered ceramic grain combined with a grinding aid lowers cutting force and helps reduce heat transfer, decreasing metal discolouration risk on sensitive alloys.

What pack quantity is supplied and how does that benefit workshops?

Units are supplied in packs of 25 which supports continuous production and reduces the frequency of replenishment in high-throughput operations.

What rotational speed can it safely withstand during use?

The disc is rated for a maximum safe speed of 15,000 r/min allowing use on high-speed grinders and automated spindles.
