HDO Black Microfiber Polishing Pad 3.5Designed for long-throw polishers specifically, the Heavy Duty Orbital (HDO) line was created to offer more durable and performance-enhancing characteristics.In line with our HDO Foam pad design, weve added the advantages of a tapered profile to our famous Microfiber pads. Having a tapered profile increases your options, opening up a wider range of appropriate cutting and polishing techniques (such as slight tilting), as well as improving access in tighter spots while simultaneously creating a safer buffer zone around your backing plate.Benefits: Stay Cool The center cooling chamber (on full-size HDO Microfiber pads) reduces the risk of overheating, increasing pad durability and improving safety. Shape and Design Design offers even pressure distribution like an exact fit pad, but shape/profile offers the precision and safety of a tapered pad. The tapered edge prevents pad rolling and provides great pad rotation. Great for curved and contoured panels. table.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; } Truck Freight: No Oversized: No
