This Bosch carbide multi-wheel allows 3 In. angle grinders to cut material they couldn’t previously, including wood, plastics, composites, wood with nails, drywall and laminates. The multi-wheel provides a long life because it features a carbide-grit cutting edge that’s bonded to the steel wheel with laser-melting technology for an extra-strong bond. It delivers professional performance in multi materials. The thin body provides fast cuts in hard-to-reach areas. It is an optimal match with the Bosch GWS12V-30 3 In. grinder. It is compatible with standard 3 In. grinders and cut saws with 3/8 In. arbors.
