3X1XLOCKIT M A/O SD 521HDU

Our Standard Abrasives™ quick-change aluminum oxide 500 series unitized wheel is a good match for light-pressure cleaning, blending and finishing on smaller areas of flat or contoured parts. This non-woven wheel may also be used on softer metals for light deburring and edge radiusing. When strict dimension tolerances are required, these wheels offer the finesse needed to deliver precise results. Among Standard Abrasives™ unitized wheels, the 500 series provides the softest density, and is available in medium (MED) and fine (FIN) grades suitable for light-weight cleaning, blending, and finishing. Use our Standard Abrasives™ aluminum oxide unitized wheel 500 series wheels for general purpose cleaning or cleaning prior to painting. Trust them to effectively remove rust discoloration from welds, and remove minor pits and scratches, as well as lightweight resins or adhesives overspray and coating. They are a good match for polishing fillet areas on jet blades and soft metals prior to the coating process. Due to their conformability, these wheels are great for projects with strict tolerances, because they respond to surface irregularities. 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. Choose the wheel 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, and 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 in TA4 mandrel attaches the holder pad to the tool. 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.
