SDC (diamond) wheels are for tungsten carbide (HM\/TCT) tools — diamond abrasive is the only one that effectively works carbide without wearing out the wheel. Using the wrong wheel results in poor sharpening and premature wear of the wheel itself.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eIs this grinding wheel compatible with my Bernardo sharpener?\u003c\/summary\u003e\n\u003cp\u003eEach Bernardo grinding wheel is specific to the model indicated in the title. Always check the sharpener model before purchasing — the outer diameter, thickness, and bore hole dimensions must match exactly. For compatibility confirmation, contact Krollit.

Replacement is necessary when the wheel is worn down to its minimum diameter or when it produces irregular sharpening despite the correct procedure. There are no fixed intervals — it depends on the intensity of use.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDelivery times?\u003c\/summary\u003e\n\u003cp\u003eOriginal spare parts available with 3–5 business days shipping.
