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 without gouging or undercutting the part. After prolonged use, the wheel may be dressed to maintain its shape.
The Standard Abrasives™ Silicon Carbide HD Unitized Wheels come in two options. Type 532 is an excellent choice for finishing applications. 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.
Compatible with a Variety of Tools Unitized wheels are typically used on a right angle grinder. A 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
