[Innovative design]: The groove can store excess polishing paste and abrasives; at the same time, it speeds up the air circulation between the paint and the polishing pad and avoids the accumulation of heat. [High-quality sponge]: Using high-density sponge, good ventilation performance, uniform elasticity, soft hand feel and easy to bend. Uniform pores, high air permeability and high tensile strength extend the service life of the polishing pad. [Easy to use]: The use of high-quality , easy to replace, improve work efficiency, and strong air permeability. Therefore, working heat can be radiated from the buckle to avoid adhesion failure due to heat accumulation on the back. [Heavy-Cut Polishing Foam Pad]: Orange Heavy-Cut Polishing Foam Pad To Remove Sanding Disc Marks, Deep Scratches, Overspray, Orange Peel & Heavy Oxidation Work Heavy Cut Polishing Compound, Ideal For Rotary Polisher. [Standard size]: The diameter of the sponge is 7 inches, for 150 mm backing plate, and the bottom fasteners can prevent scratching and scorching of the sponge during the polishing process, reducing the wear and fasteners between the sponges, and improving product reliability., Weight: 0.1322773572 Pounds, Manufacturer: Xnuiasqe
