Benchmark Abrasives 1-1/2" surface conditioning quick change discs combine flexible nonwoven abrasive material with a Type R quick-change attachment (Equivalent to 3M™ Roloc™ fastening system) for fast, controlled cleaning, blending, light deburring, and finishing. The open nylon web is filled with aluminum oxide abrasive and conforms to contoured and irregular surfaces, making these compact discs especially effective where larger abrasives cannot reach or provide the same level of control.

Available in coarse, medium, and fine grades, the 1-1/2" diameter is ideal for localized surface preparation, tight spaces, small contours, and detailed metal finishing. The quick-change attachment makes switching grades or replacing worn discs fast, helping move efficiently from stronger cleaning and oxidation removal to finer blending and finish refinement.

Applications

• Surface cleaning and preparation
• Blending surface imperfections
• Light deburring
• Removing surface oxidation and light rust
• Scratch refinement
• Cleaning and blending around welds
• Finishing contoured and irregular surfaces
• Tight-area and detail finishing
• Preparing metal for subsequent finishing operations

Recommended Materials

• Cast iron
• Steel
• Stainless steel
• Titanium
• Nickel
• Wrought iron
• Super alloys
• Copper
• Brass
• Tin
• Aluminum

Performance

The flexible open-web construction conforms to curves, contours, and irregular surfaces while providing controlled abrasive action. The compact 1-1/2" diameter gives the operator precise access to smaller work areas where a 2" or 3" disc may be too large.

Choose Coarse for stronger cleaning and surface preparation, Medium for general blending and refinement, and Fine for lighter finishing. Final surface appearance depends on the selected grade, starting surface, workpiece material, operating speed, pressure, and technique.

Machine Compatibility

Designed for compatible die grinders and hand-held pneumatic quick-change sanders equipped with a 1-1/2" Type R quick-change holder or mandrel.

Recommended Benchmark Abrasives tools include:

• Benchmark Abrasives Right Angle Pneumatic Quick Change Sander
• Benchmark Abrasives Pistol Grip Pneumatic Quick Change Sander

Always use the correctly sized Type R mounting accessory and verify that the disc, holder, and tool are all rated for the operating speed.

Safety Tips

• Use a compatible 1-1/2" Type R quick-change holder or mandrel.
• Verify that the disc is fully engaged with the holder before starting the tool.
• Never exceed the disc's 25,000 RPM maximum speed or the rating of the lowest-rated component in the assembly.
• Inspect the disc and mounting accessory for damage or excessive wear before use.
• Wear appropriate eye, hearing, respiratory, and hand protection.
• Use controlled pressure and allow the abrasive to do the work.
• Follow the operating and safety instructions supplied with the power tool and mounting accessory.
