Anatomy of a Square Pad

To create the 3M™ Square Pad 341D, we use a combination of aluminum oxide mineral, X-weight cloth backing, and resin. Each component plays a crucial role in the abrasive's performance and longevity. The X-weight cloth backing is heavy, durable, and does not deflect during use. This allows the pad to aggressively tackle channels, fillet welds, and corners. Aluminum oxide mineral delivers a soft scratch pattern that is often desirable for finishing and polishing. It is a popular choice among industrial professionals due to its fast cut and long life. The mineral is adhered to the backing in a closed coat construction, which means that it covers 100% of the backing. This greater grain density results in finer finishes.

Tips for Optimal Use

The 3M™ Square Pad 341D is made by folding strips of abrasive material over a metal eyelet to form a square pad. As the pad rotates, the corners provide fast cutting action, wearing down to expose fresh abrasive mineral. Square pads run smoothly and offer great control and access for corner weld grinding, finishing, and cleaning. They are slightly more aggressive than cross pads due to their square design, making them a good choice for tougher grinding and blending applications. The 341D square pads can be used with portable die grinders to facilitate easier and closer access to the workpiece. The metal eyelet attaches to a mandrel, which can be long or short, allowing the operator to tighten or extend the abrasive's proximity to the part. The pad is available in a range of grades and sizes, providing operators with the ability to secure a fine or coarse scratch depending on their project needs.

Conquer Corners

Square pads are versatile and can be used across industries and markets, commonly applied in metalworking and maintenance repair operations. Their square shape and cushioned pad make them a good abrasive for grinding, blending, and finishing flat surfaces, channels, and corners. They tackle these unique workpiece contours by cleanly abrading the surface with their square tips. The 3M™ Square Pad 341D is an excellent choice when faced with tight corners.
