3M 87378 Ceramic, 230 mm x 2.5 mm Thick, 36 Grade, 36 Grit 25

This cutting disc is a 230mm portable abrasive wheel designed for high‑speed metal cutting in industrial environments. It employs precision‑shaped triangular ceramic grain to Slice through ferrous materials with reduced heat generation, making it suitable for production and maintenance tasks where efficient metal removal and consistent cutting behaviour are required.

• Precision‑shaped grain reduces heat and extends service life
• 11,500 rpm maximum safe speed for fast cutting cycles
• 36‑grit abrasive for aggressive material removal
• 2.5mm thin wheel profile for Faster cuts and reduced kerf
• 22.23mm bore to fit common angle grinders

• Suitable for bevel preparation on steel components
• Ideal for weld removal in fabrication shops
• Used for cutting sheet and plate in machinery manufacture
• can be used with angle grinders in shipyard maintenance
• Suitable for automated cutting stations in production lines

The wheel uses a re‑engineered precision‑shaped ceramic triangular grain that slices rather than ploughs, lowering workpiece temperature during cutting.

Use grinders that sustain speed near the rated rpm since higher tool power maintains cutting performance and prolongs wheel life

It has a 22.23mm centre hole, compatible with widely used M14‑spindle angle grinders when used with the appropriate mounting flange.

The thinner 2.5mm profile reduces kerf and cutting time, lowering the amount of material removed per pass and improving throughput for repetitive cuts.
