Frequently Asked Questions

What is the difference between a CBN grinding wheel and a diamond grinding wheel (SDC)?

CBN (Cubic Boron Nitride) wheels are for HSS (High-Speed Steel) tools — they keep the cutting edge cool during sharpening without the risk of tempering. SDC (diamond) wheels are for tungsten carbide (HM/TCT) tools — the 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.

Is this grinding wheel compatible with my Bernardo sharpener?

Each 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. Customer support in Italian available.

How often should the grinding wheel be replaced?

A quality CBN or diamond grinding wheel typically lasts 5–10 times longer than a traditional corundum wheel. Replacement is necessary when the wheel is worn down to its minimum diameter or when it produces irregular sharpening despite correct procedure. There are no fixed intervals — it depends on the intensity of use.
