PRODUCT FAQ
-
What is the function of 3M's Standard Abrasives™ Quick Change TR HD Unitized Wheel, 821?
The unitized wheel combines durability and aggressive cutting power with flexibility. It contours to your workpiece for a smooth, even finish and helps reduce operator fatigue when tackling tough grinding tasks.
-
What are the product details of the Standard Abrasives™ Quick Change TR HD Unitized Wheel, 821?
This wheel comes in diameter size of 3 inch x thickness 1/8 inch MED Density (50 per case). It features high-strength fibers that resist wear and fray for consistent cutting results during the entire life of wheel.
-
Can you tell me why I should choose this particular abrasive unitized wheel over others on the market?
Absolutely! The Standard Abrasives™ quick-change T-R roll-on attachment system makes it very easy to change wheels quickly from tool to tool.Rapid Response serrations prevent weld damage or discoloration typically associated with other competitive products.In addition, our advanced resin bonding system minimizes smearing, reducing time needed for subsequent clean-up steps.This makes Preprocessing more efficient thereby saving production costs.
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 also able to withstand high-pressure applications and cut aggressively, making it a great choice for challenging burrs.
Use the Standard Abrasives™ Quick Change Unitized Wheel, A/O 800 Series to deburr stainless steel pipe thread, wire edges from surgical instruments, stainless steel sinks, tanks, and other equipment for the food service industry. It is also perfect for deburring gears and aircraft wing spars, and breaking edges on aluminum extrusions. When it comes to polishing, trust the Quick Change Unitized Wheel, A/O 800 Series to effectively polish stainless steel rule dies, welds on stainless steel sinks, machined surfaces, hand tools, and round tubing.
Standard Abrasives™ Quick Change Unitized Wheels are easy to use and 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.
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.
- 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 invigorate deburring, cleaning, blending, and finishing applications by helping operators reduce finishing steps, minimize costs, and achieve greater throughput. Choose the Standard Abrasives™ Quick Change Unitized Wheel, A/O 800 Series for your next project.
