Used in a high speed die grinder. Worked well. At high RPM, the wires splay outward more than I expected, but still functioned well and cleaned surfaces efficiently. This is a high quality product and will not fly apart like some of the cheaper wire wheels. It does occasionally shed a wire at high speed, so gloves, long sleeves and face shield with safety glasses are a definite requirement. I've used Weiler for years and never had a complaint about high speed use.
