Simply connect it to an air compressor, and you're ready to tackle grinding and fine polishing on materials like iron, wood, plastic, metal, marble, etc. Lower Vibration, More Stability: This random orbital air sander kit includes 3 cushioning pads (1/2/3 inches) that absorb vibrations and impacts, ensuring a smoother and more stable polishing process. Moreover, these pads can expand your polishing area and easily tackle workpieces of various shapes and curved surfaces. Optimal for Curved Surface Sanding: To tackle curved surface sanding tasks, our mini pneumatic sander provides 9 wavy foam pads (1/2/3 inches). Compared to traditional foam pads, these wavy foam pads can better adapt to various curved surfaces, even bends and irregular shapes, delivering more precise polishing results.

The yellow sandpapers, with coarser grits, are perfect for removing larger surface flaws, scratches, and wear, while the green sandpapers delicately address minor surface flaws and scratches for finer sanding tasks.
