3M 1187C Series Abrasive Disc, 100mm Disc Diameter, 36 Grit size - 7100309798

This abrasive disc is a ceramic-fibre sanding disc engineered for heavy grinding in industrial settings. It is intended for use on metalwork where fast material removal and controlled wear are required, operating on high-speed rotary tools compatible with a 16mm centre hole. Supplied in packs for workshop or production-line use, it is suitable for tasks that demand consistent cutting performance across extended run times.

Features & Benefits

• Re-engineered ceramic grain delivers Faster cut rates and longevity
• Grinding aid reduces pressure requirements and heat generation
• Stiff Fibre backing resists tear during medium to high-pressure grinding
• Durable resin bond maintains abrasive shape under heavy use
• Designed for predictable wear to reduce disc change-outs

Applications

• Suitable for weld removal on stainless steel and alloy assemblies
• Ideal for bevel preparation on fabricated metal components
• Used for surface blending in robotic grinding operations
• Can be used for Rapid material removal in mechanical workshops
• Suitable for deburring and shaping non-ferrous metal parts

What is the maximum safe rotational speed for the disc?

The disc is rated for operation up to 15,300 r/min, matching high-speed grinders used in industrial production.

How is the abrasive constructed to manage heat during grinding?

The ceramic mineral is precision-shaped and paired with a grinding aid to fracture into Sharp points that cut with lower pressure and reduce thermal build-up.

What backing and bond characteristics support heavy-duty use?

A stiff Fibre backing combined with a robust resin bond gives tear resistance and structural support for medium to high-pressure applications.

In what pack quantities is the product supplied for workshop replenishment?

The discs are distributed in packs of 25, suitable for stocking on-site for continuous operations.
