Black Silicon Carbide 100*(50+70)*25mm Sandstone Diamond Abrasive Sponge Block, Angle Edge and Thick Style
Similar to double-sided abrasive sponges, these blocks feature a sponge base coated with abrasive grains. The key difference is the higher-density sponge material, which is firmer with smaller pores and greater compactness. This structural advantage makes it ideal for applications requiring rigid abrasive action.
Typically used as a pre-polishing step before double-sided abrasive sponges, these blocks are designed for rough grinding tasks. The rigid sponge substrate provides stable support for surface abrasive grains, maintaining consistent cutting angle and excellent self-sharpening performance.
While double-sided abrasive sponges deliver smooth, mirror-like finishes, sponge abrasive blocks are tailored for grinding hard yet fragile workpieces that are prone to surface scratches. This functional distinction is reflected in their abrasive grain selection.
To ensure optimal rigidity and self-sharpening capability, these sponge blocks are often paired with high-hardness abrasives such as calcined alumina and silicon carbide. Their structural design enhances utility with trapezoidal or parallelogram forms featuring distinct edges and corners. These angular surfaces are specially suited for grinding small gaps, tight crevices, and intricate details.
Key Features
