Standard Abrasives™ A/O Unitized Wheel 892105, 921 1 in x 1 in x 3/16 in, 10 ea/Case

The Standard Abrasives™ Aluminum Oxide 900 Series Unitized Wheel is a powerful tool for heavy-duty deburring, cleaning, blending, and finishing. This wheel is available in two grades of aluminum oxide (A/O) mineral: coarse or medium. The combination of extra hard density and coarse mineral enables this wheel to withstand high-pressure applications and cut with force, making it suitable for challenging burrs and polishing harder metals.

Use a Standard Abrasives™ 900 Series A/O Unitized Wheel for removal of heavy flash and parting lines, deburring sharp edges, removal of coarse coated abrasives grind lines and removal of heavy machine tool marks. When it comes to blending, trust this wheel to blend pits in cast parts, refine surfaces on high nickel alloys and blend machined surfaces where wheel rigidity is necessary.

Unitized wheels are typically used on a die grinders. A great 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 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. 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.

Standard Abrasives™ Unitized Wheels offer many benefits for heavy-duty jobs. 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.
