Soft Density Silicon Carbide Wheel Polishes with Precise Results
Among Standard Abrasives™ Unitized Wheels, the 500 Series provides the softest density, and is available in medium (MED) and fine (FIN) grade silicon carbide (S/C). The combination of soft density and sharp-cutting S/C mineral makes these wheels a good match for applications where a fine finish is more important than cut, such as 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.

The 500 Series S/C Wheels come in two options. Type 532 is an excellent choice for finishing applications. However, the Type 524 wheel is designed to better suit light-weight blending applications by constructing it with a higher density of MED grade S/C grain throughout the web material, resulting in a slightly more aggressive product.

Silicon Carbide mineral is a good choice for both ferrous and non-ferrous metals, including exotic metals and titanium, as well as composites.

Quick Change Wheels Increase Throughput
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" TA4 mandrel attaches the holder pad to the tool (sold separately, part number 540013).

Non-Woven Unitized Construction Offers a Step Up in Density and Durability for Stubborn Surfaces
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.
