Description
Bernardo CBN Grinding Wheel for STG 42 – HSS Grinding
The CBN grinding wheel for the STG 42 sharpener is designed for grinding and resharpening high-speed steel (HSS) and hardened steel tools. Cubic Boron Nitride (CBN) ensures high hardness, thermal stability, and wear resistance, making it suitable for machining high-hardness ferrous materials. It allows for precise restoration of cutting angles, concentricity, and microgeometry of the edge, ensuring a uniform surface finish and consistent dimensional accuracy. Thanks to controlled material removal and reduced heat generation, it preserves the metallurgical properties of the tool during machining. Recommended for tool shops and mechanical workshops specializing in tool maintenance.

Frequently Asked Questions
What is the difference between a CBN wheel and a diamond wheel (SDC)?
CBN (Cubic Boron Nitride) wheels are for high-speed HSS 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 down the wheel. Using the wrong wheel results in poor sharpening and premature wheel wear.
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, please contact Krollit. Customer support available in Italian.
How often should the grinding wheel be replaced?
A quality CBN or diamond 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 following the correct procedure. There are no fixed intervals — it depends on the intensity of use.
