Standard Abrasives™ A/O Unitized Wheel 872135, 721 3 in x 1/4 in x 1/4 in, 10 ea/Case

The Standard Abrasives™ Aluminum Oxide (A/O) 700 Series Unitized Wheel is a double-duty abrasive with combined durability and fine cutting action. It has a medium to hard density compared to other wheels in the Standard Abrasives™ Unitized Wheels line. This wheel is great for an extensive list of applications that require an aggressive cut and fine finish.

The A/O 700 Series Unitized Wheel is perfect for deburring gears and the trailing and leading edge on turbine blades. It is also useful for removing punched hole burrs on stainless steel, 80 grit grind lines on nickel alloys, 120 grit grind lines on aluminum, heavy flashing and medium-sized pits and scratches. Additionally, it is great for edge radiusing, particularly on harder metals. When it comes to cleaning, trust a Standard Abrasives™ 700 Series Unitized Wheel for removing heavy scale, light oxidation from aluminum, brazing on steel tubing, weld discoloration, and handling marks prior to coating or plating.

Unitized wheels are typically used on a die grinder. A benefit of unitized wheels is that they are bi-directional and can be mounted on a tool or pedestal grinder without regard to the direction of the spindle rotation. This means the Standard Abrasives™ Unitized Wheel can be used with a variety of tools, and regardless of which way the workpiece is fed through the machine, the wheel will be able to respond, giving operators more flexibility. The stiffness of the unitized construction enables operators to use thinner wheels to access awkward angles with grinding tools.

Standard Abrasives™ Unitized Wheels are a great match for tough deburring, cleaning, blending and finishing applications. They come in a broad range of densities and grades to suit different metals, the degree of aggressiveness required, shape of the part, and desired finish. Although used for some of the same tasks as Standard Abrasives™ Buff and Blend products, they are designed with a far stronger and denser construction to support more aggressive applications and accomplish material removal more rapidly. Even though unitized wheels are much stiffer products, the non-woven nylon fibers of the wheel maintain the advantage of responding to surface irregularities while preserving the geometry of the piece, and produce a consistent finish.

Standard Abrasives™ Unitized Wheels are load-resistant to keep you cutting with fresh mineral. The gaps in the open web allow unwanted swarf to escape. Consequently, less debris clogs the abrasive, so the mineral can stay fresh, keep cutting sharp and deliver a consistent cut over the life of the product. As the fibers break down and fresh mineral is exposed, it reduces the likelihood of dull or blunt mineral smearing the surface, contributing to cleaner surfaces and less re-work. Furthermore, manual fatigue that may result from applying heavy pressure to a dull abrasive is reduced.

Series 700 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).

Unitized wheels are created by starting with layers of 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. By fusing layers of open web, the abrasive gains more toughness and durability, so it can withstand repeated wear.

Ultimately, the wheel's durability is what makes it such a good match for edges. Regardless of the diameter or thickness of the wheel, it maintains its structural integrity to remain a stiff and long-lasting abrasive even under high pressure. Additionally, as the layers wear, the wheel can be dressed to maintain its shape.

For all the aforementioned reasons, Standard Abrasives™ Unitized Wheels invigorate deburring, cleaning, blending and finishing applications by helping operators reduce finishing steps, minimize costs and achieve greater throughput.
