This flange adapts a \u003cstrong\u003e10mm bore\u003c\/strong\u003e wheel to a \u003cstrong\u003e32mm spindle\u003c\/strong\u003e, ensuring the wheel is centered and clamped securely with no wobble or runout. The 3.5mm step height and 4–5mm total thickness provide correct axial positioning for most standard bench grinder and saw setups.\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQ: Is this flange compatible with my bench grinder or saw?\u003c\/strong\u003e\u003cbr\u003e\nA: This flange is designed for machines with a \u003cstrong\u003e32mm spindle diameter\u003c\/strong\u003e where the wheel or blade has a \u003cstrong\u003e10mm bore\u003c\/strong\u003e. Verify both your machine spindle OD and your wheel\/blade bore before ordering.

A \u003cstrong\u003e3.5mm step\u003c\/strong\u003e provides a deeper, more secure engagement — suited for setups where additional axial stability is needed. A 1.5mm step is used where minimal offset is required.
