Metric-spindle grinders (sold primarily in Europe and Asia, but increasingly in US tool lineups too) use M10 metric threads, in one of two pitches: 1.25mm or 1.5mm. The grinder will reject the wrong-pitched brush even if the diameter matches.\u003c\/p\u003e\n\u003cp\u003eThis adapter has a 5\/8 in.-11 female bore (cup brush threads in) and an M10 male shank in the chosen pitch (threads into the grinder spindle).
