Arbor size must match your grinder’s spindle for safe and effective use. The most common arbor size is 7/8", which fits most standard angle grinders and provides a secure fit. Some discs also feature X-LOCK arbors for rapid, tool-free changes. The Makita T-03925 40 Grit and Makita T-03953 120 Grit both offer a 7/8" arbor and X-LOCK compatibility, ensuring broad compatibility and fast changes. A range of arbor sizes and mounting options are available, so you can select the best fit for your equipment.
