Sanding Disc 3M Cubitron II 967A 125 mm × 22 mm Grit 60

The 3M Cubitron II 967A sanding disc, 125 mm × 22 mm with grit 60, is a high-performance abrasive disc designed for aggressive material removal and consistent surface preparation. The disc uses a precision-shaped ceramic abrasive grain that fractures to form new sharp edges during use, maintaining cutting efficiency and providing longer life compared with conventional abrasives. It is produced for use with compatible angle grinders and sanding tools where a 125 mm diameter and 22 mm center hole are required.

Advantages

The Cubitron II ceramic abrasive structure offers fast cut rates and stable stock removal while reducing the amount of pressure needed from the operator. Its long service life lowers the frequency of disc changes and downtime. The consistent abrasive geometry helps produce uniform finishes on metal and other substrates and improves productivity on tasks such as weld blending and rapid shaping. The disc is balanced for rotational stability and suitable for sustained use on power tools.

Suitable for

• Rapid removal of weld seams and weld spatter
• Rough shaping and deburring of metal components
• Surface preparation before painting or coating
• Heavy stock removal on steel, stainless steel and similar alloys

Key specifications

• Disc diameter: 125 mm
• Center hole diameter: 22 mm
• Abrasive type: ceramic precision-shaped grain
• Grit: 60 (coarse)
• Recommended tool: compatible angle grinders and sanding tools for 125 mm discs
• Typical applications: metal material removal, weld blending, surface preparation

How to use

Mount the disc on a compatible backing pad and secure it according to the tool manufacturer’s instructions, ensuring the center hole aligns correctly. Operate the angle grinder at the recommended speed range for the abrasive disc and apply light, consistent pressure while allowing the disc’s cutting action to do the work. Move the disc in steady passes across the workpiece, avoid excessive dwell in one spot to prevent overheating, and maintain appropriate personal protective equipment including eye, hearing and respiratory protection.

Usage recommendations

For best results on metal, use the disc on clean, dry surfaces and replace the disc when cutting performance decreases or if the disc shows signs of damage. Allow the tool to reach operating speed before contacting the workpiece and use gradual, controlled passes to achieve even material removal. Verify compatibility of backing pad and tool RPM with the disc specifications before use.
