Overview
The Norton 662435-10625 Type 27 depressed center mini disc is a high-performance abrasive wheel engineered for rapid stock removal and fast cutting in metalworking applications. Type 27 wheels feature a depressed center design that allows operators to use the full face for efficient grinding, flashing, beveling, and weld smoothing across ferrous metals and selected specialty applications. The 4″ diameter with 1/4″ thickness and 5/8″ arbor hole makes this wheel ideal for handheld and bench grinders in fabrication shops, maintenance facilities, and production environments.
