Machine Compatibility
The bundle includes the pneumatic machine platform needed for quick-change sanding.
Compatible examples include:
- Benchmark Abrasives Right Angle Pneumatic Quick Change Sander — INCLUDED FREE

Safety Tips
- Always wear appropriate PPE, including safety glasses with a face shield as needed, hearing protection, respiratory protection when required, and suitable hand protection.
- Never exceed 90 PSI with the included pneumatic sander.
- Use only a properly sized 2" Type R backing pad with the 2" discs in this assortment.
- Inspect the disc and backing pad before every use.
- Make sure the disc is completely engaged with the Type R attachment before operating the machine.
- Verify the maximum RPM rating of the installed abrasive before use.
- Never exceed the abrasive manufacturer's maximum operating speed.
- The stripper discs in this bundle have a lower maximum speed than the other quick-change products and must not exceed 16,000 RPM.
- The included sander operates at up to 15,000 RPM.
- Disconnect the air supply before installing, removing, or changing discs or backing pads.
- Apply controlled pressure and allow the abrasive grain to perform the cutting.
- Excessive pressure can increase heat, shorten abrasive life, and reduce finishing control.
- Avoid excessive edge loading that can damage the abrasive or backing pad.
- Direct sparks and grinding debris away from yourself, other people, combustible materials, and sensitive surfaces.
- Use the included abrasives for dry applications only.
- Prolonged exposure to vibration and repetitive motion can contribute to hand, wrist, and arm strain.

The holiday bundle sells for $542.97, giving you $85.79 in savings.
That gives you complete grit coverage rather than assorted discs mixed together within individual packs.
Zirconia is a tougher, self-sharpening grain that handles greater grinding pressure and is better suited to aggressive stock removal and demanding metalworking applications.
This makes them particularly useful when working stainless steel and other applications where heat buildup can affect the workpiece or abrasive performance.
It provides aggressive cutting action and performs particularly well on stainless steel, titanium, high-nickel alloys, welds, and other applications requiring fast stock removal.
- Blending
- Cleaning
- Light deburring
