Gray Calcined material 125*75*15*27mm Abrasive Sponge Block with Angular Design for Polishing Steel and Stainless Steel
Like double-sided abrasive sponges, our sponge abrasive blocks feature a sponge core coated with premium abrasive grains. What sets them apart is the high-density sponge base—firmer, with finer pores and enhanced compactness compared to standard double-sided sponges. This structural upgrade makes them the go-to choice for heavy-duty grinding applications demanding rigid abrasive force.
Serving as an essential pre-polishing step before double-sided sponges, these blocks are engineered for rough grinding tasks. The rigid sponge substrate provides steady support for the surface abrasives, ensuring a consistent cutting angle and outstanding self-sharpening performance from start to finish.
While double-sided abrasive sponges are crafted to deliver a flawless, mirror-like polish, our sponge blocks are specially designed for hard yet fragile workpieces that are easily scratched. This functional divergence is also evident in their abrasive selection.
For maximum rigidity and self-sharpening ability, these blocks are paired with top-tier high-hardness abrasives including calcined alumina and silicon carbide. Their practical structural design—usually shaped into trapezoids or parallelograms with distinct edges and corners—boosts usability significantly. These angled surfaces are the core working areas, perfect for tackling small gaps, tight crevices, and intricate detailing work.
