The Xpeed S302M4GK 4″ Diamond Polishing Pad is a professional-grade polishing solution engineered for high-performance stone fabrication and finishing.

Features and Benefits

Designed for progressive polishing workflows, the S302M4GK pad is ideal for intermediate to final polishing stages, efficiently removing scratches, haze, or minor imperfections left from coarser abrasives. Its diamond-impregnated surface provides uniform abrasion, ensuring consistent results across the entire work area. The pad is flexible yet durable, allowing it to conform to flat or slightly contoured surfaces, which reduces the risk of uneven finishes or marks.

With a 4″ diameter, this pad is perfectly sized for detailed work, edges, and small sections where larger pads may not reach, making it versatile for both countertop fabrication and repair projects. It is compatible with standard grinders, polishers, and hand-held tools, allowing seamless integration into professional stone finishing setups.

The Xpeed S302M4GK is designed to work wet, maximizing the longevity of the diamonds while minimizing dust and heat buildup during polishing. Its high-quality construction ensures extended lifespan, consistent cutting performance, and reliable results even during heavy-duty use in stone fabrication shops or on-site installations.

Whether you’re restoring, refinishing, or giving a final polish, this pad is an essential tool for stone professionals seeking a high-gloss, scratch-free finish. Its combination of durability, precision, and versatility makes the Xpeed S302M4GK a trusted choice for achieving smooth, reflective, and professional-quality stone surfaces every time.
