CORMAK DG20M

CORMAK DG20 is an advanced spiral drill sharpener designed for professional use in industrial plants, tool rooms, and service workshops. It enables precise sharpening of high-speed steel (HSS) and cobalt drill bits in the range of ø2–20 mm. Thanks to the CBN (borazon) grinding wheel, robust construction, and a complete set of collets, the machine ensures high-quality and repeatable sharpening results.

Main advantages of the machine
Wide diameter range – allows sharpening of drills from ø2 to ø20 mm.
Adjustable point angle – from 90° to 135°, enabling precise adaptation of the cutting edge geometry to specific applications.
CBN (borazon) grinding wheel – highly durable and designed for sharpening high-speed steel drills, ensuring excellent sharpening results.
High rotational speed – the 4800 rpm motor provides fast and clean grinding performance.
No need for specialized training – the guided tool positioning system allows accurate sharpening even without extensive machining experience.
Compact design – small dimensions and a weight of 11 kg make it ideal for mobile applications and limited workspaces.
Complete equipment included – ER20 and ER25 collets with two clamping holders allow immediate operation without additional accessories.
Design and technology

The CORMAK DG20 drill sharpener is manufactured from high-quality components to ensure durability and precision. The rigid housing design minimizes vibrations, resulting in improved grinding accuracy.

The key component is the CBN grinding wheel, designed for intensive use and ensuring uniform sharpening of every cutting edge. The collet guidance system has been optimized for ergonomics and repeatability, while the 180 W motor provides sufficient power for efficient regeneration of cutting tools.

Precision and work efficiency

Thanks to precise tool guidance and the appropriate grinding wheel selection, the CORMAK DG20 drill sharpener enables the user to achieve perfect cutting edge geometry. This results in:
