3M abrasive discs Xtract 150 mm diameter pack of 50, model 39160

Pack of 50 3M Xtract abrasive discs, 150 mm diameter, model 39160 are designed for surface preparation and finishing with angle grinders and orbital sanders that accept 150 mm discs. These abrasive discs deliver consistent cutting and blending performance across metal, wood and composite surfaces and are intended for workshop and industrial environments where a steady supply of reliable discs is required.

Advantages

3M Xtract abrasive discs combine uniform grit distribution and a backing that supports even contact with the workpiece, helping to reduce clogging and prolong disc life. The discs provide predictable material removal rates and a consistent finish while supporting dust control when used with compatible extraction systems. The 150 mm size balances contact area and maneuverability for both flat surfaces and contoured parts.

Suitable for

• Surface preparation and paint or coating removal on metal
• Deburring and edge blending on welded joints
• Sanding and shaping of woodwork and furniture components
• Finishing and light stock removal on composite panels
• High-volume workshop and industrial sanding operations

Key specifications

• Disc diameter: 150 mm
• Pack quantity: 50 discs
• Abrasive type: coated abrasive (Xtract series)
• Compatible tools: angle grinders and sanders that accept 150 mm discs
• Typical applications: metal, wood, composites

How to use

Fit the 150 mm disc to a tool that accepts this disc size according to the tool manufacturer’s instructions, ensuring the disc is secured and centered on the backing pad or flange. Operate the grinder or sander at the recommended speed and apply even pressure, allowing the abrasive to do the cutting rather than forcing the disc. Maintain stable tool movement across the surface to achieve an even finish and avoid concentrating on a single spot for extended periods.

Usage recommendations

Use appropriate personal protective equipment, including eye, hearing and respiratory protection. Where possible, use compatible dust extraction to capture particles generated during sanding. Replace discs when wear reduces effectiveness or when the backing is damaged. Test on a small area before full-scale use to confirm desired finish and compatibility with the substrate.
