Standard Abrasives™ A/O Unitized Wheel 882175, 821 6 in x 1/2 in x 1 in, 4 ea/Case

The Standard Abrasives Aluminum Oxide 800 Series Unitized Wheel is a high-performance abrasive wheel designed to remove challenging burrs with precision and impart a fine polish. This wheel is available in two grades of aluminum oxide mineral: coarse or medium. With its hard density, it falls on the upper end of the aggressiveness spectrum among Standard Abrasives Unitized Wheels. The coarseness of the mineral and the greater density allow this wheel to withstand high-pressure applications and cut aggressively, making it ideal for deburring and polishing tasks.

When it comes to deburring, the Standard Abrasives 800 Series Unitized Wheel is perfect for removing burrs from stainless steel pipe threads, wire edges from surgical instruments, stainless steel sinks, tanks, and other equipment used in the food service industry. It is also a prime choice for deburring gears and aircraft wing spars, as well as breaking edges on aluminum extrusions. In terms of polishing, the 800 Series A/O Unitized Wheel is highly effective in polishing stainless steel rule dies, welds on stainless steel sinks, machined surfaces, hand tools, and round tubing.

The Standard Abrasives Unitized Wheel is compatible with a variety of tools, making it versatile and convenient to use. It is typically used on a die grinder, but it can also be mounted on a tool or pedestal grinder without regard to the direction of the spindle rotation. This bi-directional feature allows operators to use the wheel with different tools and feed the workpiece through the machine in any direction. The stiffness of the unitized construction enables operators to use thinner wheels to access awkward angles with grinding tools. The Series 800 wheels come in a range of diameters from 1-6 and require a unitized wheel mandrel (sold separately) for attachment to the tool. Quick change wheels are also available (sold separately).

Standard Abrasives Unitized Wheels are specifically designed for tough deburring, cleaning, blending, and finishing applications. They are constructed with a non-woven unitized construction that offers a step up in density and durability for stubborn surfaces. These wheels come in a broad range of densities and grades to suit different metals, the required level of aggressiveness, the shape of the part, and the desired finish. Unlike Standard Abrasives Buff and Blend products, unitized wheels are designed with a stronger and denser construction to support more aggressive applications and accomplish material removal more rapidly. Despite their stiffness, the non-woven nylon fibers of the wheel allow it to respond to surface irregularities while preserving the geometry of the piece, resulting in a consistent finish.

Unitized wheels are created by layering open web material that combines non-woven fiber strands and abrasive mineral with a tough resin bond. These layers of web are then cured and compressed together, giving the abrasive more toughness and durability to withstand repeated wear. The durability of the wheel allows it to maintain its structural integrity, making it an excellent choice for edges. Regardless of the diameter or thickness of the wheel, it remains stiff and long-lasting even under high pressure. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.

Standard Abrasives Unitized Wheels are load-resistant, ensuring a longer product life and consistent performance. The gaps in the open web structure of the wheel allow unwanted swarf to escape, preventing debris from clogging the abrasive. This allows the mineral to stay fresh, sharp, and deliver a consistent cut throughout the life of the product. As the fibers break down and fresh mineral is exposed, the likelihood of dull or blunt mineral smearing the surface is reduced, resulting in cleaner surfaces and less re-work. Furthermore, the load-resistance of the wheel reduces manual fatigue that may occur from applying heavy pressure to a dull abrasive.

Standard Abrasives Unitized Wheels offer numerous benefits for heavy-duty jobs. They invigorate deburring, cleaning, blending, and finishing applications by helping operators reduce finishing steps, minimize costs, and achieve greater throughput. With their high-performance construction and versatility, Standard Abrasives Unitized Wheels are a reliable choice for professionals in various industries.
