12.7mm Bore to 16mm Step Arbor Reducer Flange – Precision 1.5mm Adapter for Grinding & Saw Blade Mounting

A precision-machined arbor reducer flange that adapts a 12.7mm (1/2") bore wheel or blade to a 16mm step diameter spindle. With a 1.5mm step height and 4–5mm total adapter thickness, this low-profile flange provides a stable, centered clamping surface for setups requiring minimal axial offset. Designed for bench grinders, lapidary machines, and diamond saw setups where bore-to-spindle mismatches require a reliable, vibration-free solution.
