A high density wheel designed with extra tough edge durability, the Standard Abrasives Quick Change Aluminum Oxide 800 Series Unitized Wheel is a good match for heavy-duty edge deburring and stainless steel polishing applications on smaller areas of the workpiece.
- Combining a high density wheel with medium or coarse mineral results in superior edge deburring and polishing
- Harder material and increased edge durability over 700 Series Unitized Wheels increases life for heavy-duty tasks
- Aluminum oxide mineral is a good match for ferrous and non-ferrous metals, including aluminum
- Open web is load resistant, contributing to longer abrasive service life
- Easy fastening and swapping of quick change disc enhances tool efficiency and worker productivity

PRODUCT FAQ
-
What is the Standard Abrasives Quick Change Aluminum Oxide Unitized Wheel 821?
It's a hard-wearing abrasive wheel that helps you achieve a fine finish on metal surfaces.
-
What size is it?
This specific unitized wheel measures 3 inches in diameter and 1/4 inch thick.
-
How can I use it?
You can attach this unitized wheel onto a power tool with its quick-change feature to sand, deburr or blend small surfaces easily.
-
What does "Hard 8A Medium TSM" mean? Is it suitable for my needs?
Hard 8a medium refers to the firmness of the abrasive material with an intermediate grit grade suitable for general purpose applications. Also, TSM stands for Tool Shanks Mount and this product comes in compatible mount sizes as marked. Depending on your application requirement, our sales executives can help pick up the right one from various grades ranging between extra coarse (XC) to very fine (VF).
-
: Does this come as a single piece ?
A : No, These are sold by cartons which contain ten units per box so you never have a shortage during projects or profressional commitments.
The Standard Abrasives™ Quick Change Unitized Wheel, A/O 800 Series is a non-woven abrasive wheel that comes in two grades of aluminum oxide (A/O) mineral: coarse or medium. This wheel is highly aggressive due to its greater density and coarseness of the mineral, making it ideal for deburring and polishing smaller areas of the workpiece. It is able to withstand high-pressure applications and cut aggressively, making it a prime choice for deburring gears and aircraft wing spars, breaking edges on aluminum extrusions, and polishing stainless steel rule dies, welds on stainless steel sinks, machined surfaces, hand tools, and round tubing.
Standard Abrasives™ Quick Change Unitized Wheels are available in smaller sizes with a TS or TR attachment. Quick change wheels allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications. Easy fastening and swapping of wheels enhances tool efficiency and worker productivity. Unitized wheels are bi-directional and can be mounted to the tool without regard to the direction of the spindle rotation.
Standard Abrasives™ Quick Change Unitized Wheels, A/O 800 Series 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.
- Choose the disc compatible with your TR or TS holder pad.
- TR wheels have a nylon threaded male hub that easily threads onto TR or 3M™ Roloc™ type holder pads with a turn of the wrist.
- The TS system has a metal hub that fastens to its holder pad with a simple twist.
- All Standard Abrasives™ TS and TR holder pads have a 1/4-20 female thread.
- A 1/4" TA4 mandrel attaches the holder pad to the tool (sold separately, part number 540013).
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 invigorate deburring, cleaning, blending, and finishing applications by helping operators reduce finishing steps, minimize costs, and achieve greater throughput.
