The high-performance CBN borazon grinding wheel designed for the CORMAK DG20M drill sharpener is a key component ensuring precise sharpening of drills made of HSS high-speed steels and cobalt steels. It offers exceptional durability and accuracy essential in daily operations of toolrooms, mechanical workshops or maintenance departments.
Main advantages of the DG20 grinding wheel

High hardness and thermal resistance thanks to the CBN (borazon) abrasive material.
Compatibility with the CORMAK DG20M sharpener – a wheel designed for this model guarantees perfect fit and maximum efficiency.
Vibration-free operation due to precise balancing – reduces the risk of tool damage and improves user comfort.
Long service life – significantly reduced replacement frequency and lower operating costs.
Stable geometry – no need for frequent shape correction, enabling consistent sharpening quality.

Construction and technology
Rcedpeycq Hrefx Aa Isf

The grinding wheel for the CORMAK DG20M drill sharpener is manufactured with CBN technology – borazon is one of the hardest abrasive materials known, ideally suited for machining high-speed steel tools. Thanks to precise workmanship and an optimised profile, the wheel ensures high sharpening efficiency while minimising material loss from the tool.
Precision and work efficiency

The use of an original CBN wheel in the CORMAK DG20 model provides excellent results even during long operating cycles. The wheel maintains an accurate point angle (within 90–135°), which affects cutting quality, reduces cutting forces and increases the service life of sharpened drills. Its vibration-damping properties minimise the risk of micro-chipping on cutting edges.
