Original Makita inner flange (part no. 122444-5) — a metal inner flange assembly with a 47 mm seating face used on many Makita angle grinders. It has a central bore of about 14 mm and a flange thickness roughly 13 mm, sized to accept the standard M14 clamping nut and support cutting / grinding discs.
This genuine Makita replacement matches the factory part used in the gearbox / guard stack and is supplied as the complete inner flange assembly so you can reinstall the lock nut and disc without additional modifications. Fits models shown in Makita parts for GA9020 / GA9020S and GA9040R, and grinders in the 9067 / 9069 / 9079 and some 230 mm Makita angle grinders.
