Any powered wheel, cylinder, disc, belt or point which is constructed from, or coated with abrasive particles is considered an abrasive wheel.

Today there are literally thousands of shapes and sizes of abrasive tools available for use, but they all have the same basic purpose intended to remove material from an object so that object may be used for a given purpose. This removal can vary in application. Some of the more commonly occurring tasks include cutting a piece of metal to achieve a specific shape, grinding a piece of metal to remove sharp edges or to shape it, removing paint or rust from a metal surface, cutting stone or brick slabs, precision engineering using a tapered point abrasive, and using a belt sander to clean a wooden floor prior to applying a wood stain. Each of these tasks will require a specific and different type of abrasive.

In general there are two different types of abrasives. A wheel bonded abrasive and coated abrasive. Major abrasive manufactures include Saint Gobain, 3M, Atlas Copco, Ingersoll Rand, Chicago Pneumatic, Desoutter, Rupes, Fein, Sia Abrasives, ATA, and others.

Saint-Gobain Norton
Saint-Gobain Norton (formerly known as Saint-Gobain Abrasives) is one of the world's largest manufacturer and supplier of performance engineered abrasives for technical manufacturing and commercial applications and general household and automotive refinishing solutions.
Saint-Gobain Norton wheels are a class of bonded abrasive wheels that are 1mm to 6mm thick. They utilize resin bonds and are often reinforced with fiberglass. They can grind and cut both ferrous & non-ferrous metals as well as building materials including welding, pipe, construction, foundry and metal fabrication markets.
Saint-Gobain Abrasives has recently introduced Norton QUANTUM™ X Creepfeed Wheels featuring three proprietary technologies to create the "ultimate" wheel for free-cutting. The leading Norton technologies that comprise QUANTUM X include a patented pore-induced construction, Norton Quantum ceramic abrasive and the latest, strongest patented bond from Norton. The new wheels are positioned in the "Best" tier of Norton grinding products to provide the best metal removal rates compared to all other ceramic creepfeed wheels.

The QUANTUM X wheels are ideal for a variety of applications ranging from low to medium and high-force on heat sensitive, hard-to-grind inconel, titanium and aerospace alloys. These new creepfeed wheels excel on large areas of contact applications and offer exception form and corner-holding.

3M abrasive power tools

3M pneumatic tools are designed to optimize tool and abrasive performance during cutting, grinding, blending or finishing applications. Their design and advanced technology increase comfort by directing exhaust away from the operator. Tools in this category include: cut-off wheel tools, die grinders, disc sanders, inline sanders, orbital & nib sanders, random orbital sanders & buffers.

Atlas Copco
Atlas Copco is an industrial group with world-leading positions in compressors, construction and mining equipment, power tools and assembly systems. The products and services range from compressed air and gas equipment to construction and mining equipment and industrial tools and assembly systems.

GTG40 series turbo air grinder
The turbine motor used in the GTG40 series turbo air grinder is more efficient than a conventional grinder motor. Therefore it takes less time to do the same job. Also the total air consumption will be a lot less for a specific job.
The GTG/GTR40s are the most powerful grinders in the Turbo grinder range, with incredible power for their size and weight. The range includes angle and straight type grinders for virtually every common rough grinding application.
• GTG40 F – for rough grinding and cutting off with depressed center wheels.
• GTG40 S – for surface finishing with coated abrasives and wire brushes.
• GTG40 C – for rough grinding with cup wheels.
• GTR40 – for rough grinding and applications such as internal and external cleaning of
 castings with straight grinding wheels.
• Dust extraction – Efficient accessory and standard model for extraction of air-borne dust
 in sanding applications with fiber discs.

Brazor Mark II air grinder
Atlas Copco's Brazor Mark II electric air grinder is designed for pure material removal, regardless of whether it is removed from a cramped or an open space, and is determined by the power generated at the grinding process.
All models are equipped with the highly efficient G71 motor and the system will generate superior power with <10% energy losses. This, in combination with the features stated below, makes Brazor Mark II a safe and ergonomic choice for the most efficient grinding, cutting and sanding:
• Power feedback for most efficient material removal.
• Minimal abrasive costs due to small angle head, speed control and low vibrations.
• Reduced service costs and minimum downtime thanks to overload protection,
temperature control and service indicator.
• Full mobility and no installation required.
• Built-in Ground Fault Interrupter (GFI) in PU for electricity safety.
• Superior ergonomics with low vibrations.
• Service indicator notifies you of preventive maintenance for longer operational life.

Ingersoll-Rand Inc is an Irish global diversified industrial company founded in 1871. The Ingersoll Rand name came into use in 1905 through the combination of Ingersoll-Sergeant Drill Company and Rand Drill Company. Ingersoll Rand is a brand for air compressors, tools, material handling devices and more.
