POLINOX hand pads from PFERD are a versatile and cost- effective answer to a range of grinding and cleaning needs. Suitable for very fine grinding on small to large surfaces and contours, and for manually cleaning metal and painted surfaces, they are highly flexible, enabling optimal adjustment to the contour of the workpiece. This allows users to access hard-to-reach areas.
The pads can achieve matte and satin-finished surfaces and can be used for wet or dry grinding. Well-suited for light deburring work, corrosion removal, cleaning jobs in tool and moldmaking, and fine grinding/patterning of stainless steel. Made from nonwoven material with a highly open structure impregnated with either aluminum-oxide A or silicon-carbide SiC grain, PFERD hand pads, which can be supplied in bulk quantities, follow industry-standard color coding for easy selection.
Maroon-colored general-purpose pads are the most widely used of all hand pads. Their aluminum oxide grain is noted for its toughness and durability on tasks such as cleaning, deburring, rust removal, blending and finishing.
Green-colored pads are general-purpose grade pads made with aluminum oxide. Commonly, though not exclusively, used in the food service industry, these pads are recommended for light-duty and finishing applications.
Tan-colored heavy-duty pads consist of a dense aluminum-oxide grain concentration on heavy backing material. Designed for the most severe applications, they are extremely durable and resist tearing and fraying. Excellent for removal of oxidation, weld cleaning, deburring and finishing stainless steel and aluminum.
The white-colored hand pad contains no abrasive. It is used primarily for applying lubricants, detergents and polishes to almost any material. Commonly used for cleaning plastics, glass, ceramics, porcelain, chrome, copper and stainless steel.
And finally, the gray-colored pad is an ultrafine silicon-carbide pad that provides a precise, fine cutting action. Well-suited for light cleaning and fine finishing on a variety of material including metal, plastic, glass and wood.

- aluminum oxide
Aluminum oxide, also known as corundum, is used in grinding wheels. The chemical formula is Al2O3. Aluminum oxide is the base for ceramics, which are used in cutting tools for high-speed machining with light chip removal. Aluminum oxide is widely used as coating material applied to carbide substrates by chemical vapor deposition. Coated carbide inserts with Al2O3 layers withstand high cutting speeds, as well as abrasive and crater wear.
1. Flexible portion of a bandsaw blade. 2. Support material behind the cutting edge of a tool. 3. Base material for coated abrasives.
Cutting tool materials based on aluminum oxide and silicon nitride. Ceramic tools can withstand higher cutting speeds than cemented carbide tools when machining hardened steels, cast irons and high-temperature alloys.
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
