Description

Bernardo SDC Diamond Grinding Wheel for STG 42 – Carbide

The SDC diamond grinding wheel for the STG 42 sharpener is designed for grinding and resharpening operations on carbide tools, tungsten carbide, and sintered materials with extremely high hardness. The synthetic diamond abrasive (SDC) ensures high controlled material removal capacity, profile stability, and maintenance of the cutting edge geometry even during intensive work cycles. Suitable for tool rooms and mechanical workshops specializing in tool maintenance, it allows for precise restoration of cutting angles, concentricity, and micro-geometry of the edge. Use with coolant improves heat dissipation and extends the operational life of the grinding wheel.

Frequently Asked Questions

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

CBN (Cubic Boron Nitride) grinding wheels are for high-speed HSS steel tools — they keep the cutting edge cool during sharpening without the risk of tempering. SDC (diamond) grinding wheels are for tungsten carbide (HM/TCT) tools — diamond abrasive is the only one that effectively works carbide without wearing out the grinding wheel. Using the wrong grinding wheel produces poor sharpening and premature wear of the grinding wheel itself.

Is this grinding wheel compatible with my Bernardo sharpener?

Every 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 grinding wheel. Replacement is necessary when the grinding 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.
