3M Ceramic Abrasive Disc Cutting Disc, 152.4 mm, 320+ Grade, 50 Grit

This adhesive-backed/PSA sanding disc is a 150mm abrasive engineered for heavy stock removal and finishing across a range of substrates. It combines precision-shaped grain mineral chemistry with a Durable J-weight cloth backing and a pressure-sensitive adhesive attachment to deliver consistent cutting on metals, timber and composites when used with hand or orbital sanders and compatible vacuum systems.

• Precision-shaped grain provides continuous fracturing for sustained cut
• Open-coat construction reduces loading for longer abrasive life
• Anti-static treatment neutralises charged swarf to aid dust management
• Cloth J-weight backing balances wear-resistance with flexibility
• PSA attachment enables Rapid disc changes and secure adhesion

• Suitable for metal finishing and deburring operations in fabrication
• Ideal for smoothing gelcoat and fibreglass components
• Used for blending and finishing aluminium and hardwoods
• Can be used for heavy stock removal on composite panels
• Suitable for hand or orbital sanders with vacuum back-up pads

The mineral fractures into new cutting points during use, preserving sharpness and extending run time without Rapid glazing.

It reduces static charge on dust and swarf, helping vacuum systems collect debris more effectively and reducing material cling to surfaces.

The J-weight cloth combines tear resistance with pliability, enabling the disc to withstand aggressive sanding while conforming to contoured parts.

Use with a multi-hole back-up pad and a random orbital Sander fitted to a vacuum system to maximise extraction and minimise loading.
