3M 1187C Precision Shaped Ceramic Grain Grinding Disc, 115 mm, 60+ Grit 25

This Fibre disc is a high-performance abrasive designed for heavy material removal and finishing in industrial metalworking contexts. It fits angle grinders with a 22mm centre hole and operates at elevated peripheral speeds, providing a balance of aggressive cutting and controlled wear for tasks in automation, electronics, electrical and mechanical workshops.

• Precision-shaped ceramic grain delivers Faster cut rate and cooler cutting
• Stiff Fibre backing offers resistance to tear during high-pressure work
• Grinding aid reduces required operator pressure and metal discolouration
• Maintains Sharp cutting points for prolonged usable life
• Suitable for robotic operations due to Durable resin bond

• Suitable for weld removal on stainless steel and alloy components
• Ideal for bevel preparation in mechanical assemblies
• Used for medium- to high-pressure grinding in fabrication shops
• Suitable for surface conditioning prior to electronic enclosure assembly
• Used with angle grinders in automation equipment maintenance

The disc is rated for a maximum peripheral speed corresponding to 13,300 rpm and should not be exceeded to maintain structural integrity.

The abrasive incorporates a grinding aid and a ceramic mineral that fractures to expose fresh cutting points, which reduces heat build-up and helps limit stress cracking on heat-sensitive alloys.

A combination of a stiff Fibre backing and a strong resin bond provides tear resistance and supports sustained performance across repeated cycles.

It is supplied in bags containing 25 discs to support workshop stock rotation and minimise downtime.
