Shank Mounted:Bore diameter is the inner diameter (ID) of the product's center mount. The bore is used to mount or hold the abrasive on a spindle or mandrel. The shank diameter is the diameter of the integral shank, pin, shaft, or mandrel on mounted points or wheels.

Thread Mounted:Products have a threaded hub for mandrel, arbor, spindle, or shaft mounting.

Arbor Hole:Internal grinding utilizes smaller diameter wheels or abrasive products for grinding or finishing the surface on the inner diameter of a part.

Interleaved:Interleaf flaps consist of interleaved layers of coated abrasives and non-woven abrasive products in a flap wheel configuration. Combination sheets can consist of a coated sheet bonded to a non-woven sheet. Other combinations are possible such as coated abrasive flaps combined with ball peen flaps, abrasive bristles, or other unlisted abrasive products.

Other:Other shaped flap wheels.

Aluminum Oxide:It is the most common industrial mineral in use today. Fused aluminum oxide is produced synthetically by melting bauxite and additive in an arc furnace to form a fused aluminum oxide ingots, which are later crushed and sized. The various types of fused aluminum oxides are distinguished by the levels of chemical impurities remained in the fused mineral. Fused aluminum oxide is available in several variations depending on composition and processing.

Boron Carbide:Boron Carbide (B4C) is a grey-black colored super hard abrasive with metallic luster. It is one of the hardest man-made materials available in commercial quantities and has a finite melting point which is low enough to make it easier for fabrication into shapes.

White Aluminum Oxide:White fused alumina is a kind of synthetic mineral with a high purity. It is the most friable grain in the fused alumina family.

Silicon Carbide:Silicon carbide (SiC) is a synthetic abrasive that was first developed in the late 1800s. It is harder than aluminum oxide, but more friable than grains of fused aluminum oxide. Typically, silicon carbide is used with nonferrous materials such as brass, aluminum, or titanium. The high solubility of carbon and silicon in iron would cause silicon carbide to react with an iron base alloy and result in poor grinding performance. Levels and types of impurities distinguish the green and black forms of silicon carbide. SiC's sharp and easily fractured abrasive grains are used for abrading other non-metals such as the stone, glass, wood, and leather. Like diamond, silicon carbide is susceptible to oxidation at higher temperatures.

Zirconia Alumina:It is a high performance abrasive which possesses the unique attribute of great toughness and the highest durability. The material is also able to withstand very high temperatures without the loss of utility. It possesses a good resistance to corrosion.

Ceramic Aluminum Oxide:Ceramic Aluminum Oxide is a self-sharpening grit that outperforms aluminum oxide in terms of hardness, toughness and life when used under identical conditions. It’s a new type of abrasive that was first invented and applied in 1983 by US company 3M, since then a variety of ceramic aluminum oxides have been developed.

Natural Abrasives:Compared to synthetic abrasives, it refers to abrasives’ raw materials obtained directly from the nature.

Combination:It refers to mix several kinds of abrasive grains together.

Specialty:Other specialty, proprietary or patented abrasive grain, grit or abrasive material.
