Reinforced for Tough Weld Grinding Rigid and tough in every detail, our 3M™ Green Corps™ Reinforced Weld Grinding Wheel is a small yet powerful tool for weld grinding, removing welds from internal angles and other tough grinding applications in collision repair. This 3” wheel features a tough scrim made from fiberglass cloth screen for reinforcement and longer wheel life. The 3/16”-thick wheel is ideal for use on right angle grinders, and for grinding in hard-to-reach locations. Resin bonding resists heat, and tough aluminum oxide abrasive cuts fast and lasts longer than other abrasive materials. Safe and Secure Attachment A 3/8” threaded center hole makes for secure attachment to handheld grinding equipment. The Green Corps™ Reinforced Weld Grinding Wheel must have a maximum operating speed greater than or equal to the maximum operating speed of the grinder used, and on a right angle grinder must be run with a wheel guard that is designed specifically for the size of wheel. Hard, Tough and Sharp 3M™ Green Corps™ Reinforced Weld Grinding Wheel features aluminum oxide mineral abrasive, popular among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive. Due to its fast cut-rate, hardness, strength, and low heat retention, aluminum oxide is suitable for a wide variety of materials, including ferrous alloys and aluminum alloys. Better Science for Better Grinding from 3M Heavy-duty grinding can be critical for timely, professional collision repair, and 3M delivers features for safe and effective weld grinding and other applications. With its scrim reinforcement and fast-cutting, long-lasting mineral abrasive, our Green Corps™ Reinforced Weld Grinding Wheel is another great example of how 3M applies science to life – and helps you get the most from your operations.
