A generic wheel might have incompatible dimensions or an unsuitable profile for the guided sharpening operations of the NTS 250. Always replace with the original Bernardo wheel for the NTS 250.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhen should the grinding wheel be replaced?\u003c\/summary\u003e\n\u003cp\u003eThe grinding wheel should be replaced when: the diameter has reduced to the minimum indicated in the manual (the periphery reduces with use), the surface has become shiny and no longer sharpens effectively (requiring dressing with a diamond dresser), there are visible cracks or chips (replace immediately — risk of breakage during use).
