Features and benefits
High hardness and durability:

CBN is the second hardest material after diamond, making these wheels highly resistant to wear and ideal for grinding hard steels.
Precision and efficiency: CBN wheels are highly efficient and hold their shape, so they don't require truing or dressing. This ensures a consistent and precise sharpening process.
Low heat generation: They produce less heat than traditional grinding wheels, which helps prevent overheating and damaging the delicate edges of your drill bits.

Dual abrasive options: Many manufacturers offer "CBN/SDC" wheels, which contain both cubic boron nitride and synthetic diamond compound. This allows for the versatile sharpening of both high-speed steel and carbide tools.
Compatible with many sharpeners: They are designed to fit a variety of compact electric drill sharpeners, making them a standard replacement part for many models.
