3M 947D Flap Disc 178mm Grit 60

The 3M 947D flap disc 178mm with 60 grit is a professional-grade abrasive tool engineered for efficient material removal and surface finishing. Designed for use with angle grinders, this flap disc combines high-performance ceramic abrasive grain with a durable backing to ensure consistent results on metal surfaces. Its construction allows for simultaneous grinding and blending, making it an essential component for heavy-duty metalworking tasks where precision and speed are required.

Advantages

This flap disc offers exceptional durability and a long service life, even under high-pressure applications. The ceramic grain technology provides a fast cut rate, which significantly reduces the time required for grinding and finishing operations. Furthermore, the design promotes a cooler cutting action, minimizing the risk of heat discoloration on the workpiece. The consistent wear pattern of the flaps ensures that the abrasive remains effective throughout its entire lifespan, providing a uniform finish from start to finish.

Suitable for

• Heavy-duty grinding of metal surfaces
• Removing weld seams and spatter
• Blending and finishing metal components
• Deburring sharp edges
• Surface preparation prior to coating or painting

When it may not be suitable

This disc is specifically optimized for metalworking and may not be suitable for grinding soft materials like wood, plastic, or rubber, as these can clog the abrasive flaps. It is also not intended for precision polishing tasks that require very fine grit finishes.

Key specifications

• Diameter: 178mm
• Grit size: 60
• Abrasive type: Ceramic grain
• Compatibility: Standard angle grinders

How to use

To use the 3M 947D flap disc, ensure that your angle grinder is disconnected from the power source before mounting the disc onto the spindle. Secure the disc firmly using the appropriate locking nut. Once mounted, wear appropriate personal protective equipment, including safety glasses and gloves. Position the disc at a shallow angle against the workpiece to achieve the best material removal rate and surface finish. Apply steady, even pressure while moving the grinder in a consistent motion across the surface.

What to consider before purchase

• Ensure the 178mm diameter is compatible with your angle grinder guard size
• Verify that the 60 grit is appropriate for your specific material removal requirements
• Check that your equipment supports the maximum operating speed of the disc

Usage recommendations: Always inspect the disc for any signs of damage or wear before each use. Do not exceed the maximum rated RPM of the disc to ensure safe operation. Store the discs in a dry environment to maintain the integrity of the abrasive backing.
