Product Details
The 3M™ 60440201931 PSA Cloth Disc 348D measures 20 inches in diameter and features a 50 grit aluminum oxide abrasive, making it suitable for various applications such as blending, deburring, grinding, and sanding in both metal fabrication and primary wood and panel processing industries. This heavy-duty sanding disc is equipped with a high-strength pressure-sensitive adhesive backing, allowing for efficient attachment to a backup pad or steel platen while ensuring clean removal. The disc is designed with a heat-resistant resin bond and cloth backing, enabling it to withstand high heat and heavy-duty sanding tasks. Its closed coat of aluminum oxide particles facilitates a fast cut for grinding and dual action sanding on metal surfaces. The disc is ideal for deburring, blending, cleaning, and finishing metal parts of diverse sizes and shapes, and its aluminum oxide abrasive is highly regarded by industrial professionals due to its fast cut-rate and durability. The mineral self-fractures during use to reveal fresh cutting edges, distinguishing it from traditional abrasives like garnet, which wear down more quickly. Additionally, the heat-resistant resin binding agent ensures that the abrasive remains securely attached to the backing, maintaining bond stability under high heat or pressure conditions.
