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 Bench Grinder uses Ø 300 mm grinding wheels — check the correct size 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).
