For tool sharpening and precision work: medium grit wheel (80–120). For finishing and polishing: fine grit wheel (150–220) or felt disc. The Bernardo DS 1 Double Grinder uses Ø 175 mm wheels — check the correct format before purchasing spare parts.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow often should grinding wheels be balanced?\u003c\/summary\u003e\n\u003cp\u003eNew grinding wheels should always be checked before installation (ring test — clear sound = intact wheel). Periodic dressing with a wheel dresser maintains the correct shape and reduces vibrations.
