3M sanding disc 178 mm SC-DH 60987 for machines

3M sanding disc 178 mm SC-DH 60987 for machines is a durable abrasive disc designed for machine sanding of wood, metal and painted surfaces. With a 178 mm diameter, the disc attaches to compatible backing pads and offers consistent material removal, smoothing and finishing performance for both professional and DIY applications. The product is built to provide reliable wear characteristics and repeatable results when used with orbital and rotary sanding machines that accept this size.

Advantages

The sanding disc delivers uniform abrasion across the working surface, enabling even stock removal and predictable surface profiles. Its construction supports secure attachment to machine backing pads for stable operation and reduced vibration. The abrasive material is formulated to balance cutting efficiency with lifespan, offering a consistent finish over multiple jobs. The disc's size and shape allow access to medium-sized surfaces and edges while maintaining good dust extraction compatibility when used with appropriate dust collection systems.

Key specifications

How to use

Mount the disc securely to a compatible backing pad according to the machine manufacturer's instructions. Start sanding at low to medium speed and apply even, moderate pressure while moving the machine along the workpiece to avoid creating uneven spots or grooves. For best results, progress through appropriate grit stages if using multiple abrasive grades, and keep the sanding area clean of debris. When working on painted or metal surfaces, ensure proper ventilation and follow safety guidelines for dust and particles.

Recommendations

Use the disc with a backing pad that matches the 178 mm diameter and with a compatible machine type. Replace the disc when abrasive performance declines or if the disc becomes damaged. For improved dust control and finish quality, use with an extraction system and follow recommended speed ranges for the material being sanded.
