Frequently Asked Questions

Grinding wheel for NTS 250 Top / NTS 250 Vario — what distinguishes it from a standard wheel?

The wheel for NTS 250 is calibrated for the specific geometry of the NTS 250 knife sharpener — width, bore hole, and working face profile are optimized for the machine's angle guides. 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.

When should the grinding wheel be replaced?

The 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). Original spare parts available with 3–5 business day shipping. Customer support in Italian available.
