Anatomy of a Square Pad
To construct 3M™ Square Pad 747D we adhere 3M™ ceramic grain to an X weight cloth backing using resin. Each ingredient plays an important role in the abrasive's performance and longevity. We engineer 3M™ ceramic grain using a proprietary process, which enhances toughness and hardness of the grain. Ceramic blend products feature aluminum oxide blended with ceramic grain for a harder, longer lasting abrasive. Perfect for stock removal, ceramic abrasives are engineered to fracture frequently for a super fast cut and can handle intense heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut rate and durability and makes 3M™ Square Pad 747D an excellent choice for moderate stock removal and surface preparation on a variety of metals, including nickel and stainless steel.
The X weight cloth backing is durable, heavy and won't deflect when run. It helps the pad aggressively tackle channels, fillet welds and corners. The mineral is adhered to the backing in a closed coat construction — meaning the mineral covers 100% of the backing. The greater grain density of this coated abrasive equates to finer finishes.
Tips for Optimal Use
Strips of abrasive material are folded over a metal eyelet to form a square abrasive pad. As the pad rotates, the corners provide fast biting action, wearing down to expose fresh mineral. Square pads run smoothly and offer great control and access for corner weld grinding and cleaning. They are slightly more aggressive than cross pads given their square design, so they're a good choice for tougher grinding and blending applications. The 3M™ Square Pad 747D may be used with portable die grinders to facilitate easier and closer access to the workpiece, and the metal eyelet attaches to a mandrel —long or short — enabling the operator to tighten or extend the abrasive's proximity to the part. For added versatility, the pad is available in a range of grades and sizes, so operators can secure a fine or coarse scratch depending on their project needs.
Conquer Corners
Square pads are useful across industries and markets, commonly applied in metalworking and maintenance repair operations. Altogether, their square shape and cushioned pad render 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. Our 3M™ Square Pad 747D is great to have on hand when you find yourself in a corner.
