JCB Polycrystalline Diamond Abrasives APC4 is produced using high-quality Polycrystalline Diamond (PCD) as raw material, undergoing processes such as crushing and sieving to create an ultra-hard abrasive material. The product features irregular crystal shapes, a rough and sharp surface, and is primarily used in the manufacture of heavy-duty metal bond tools and diamond impregnated drill bits. It is designed for applications involving the machining of stone, concrete, construction materials, grinding wheel dressing tools, and drilling in medium-hard rock formations.
