CORMAK DG13MD

CORMAK DG13MD is a high-quality spiral drill sharpener designed for professional sharpening of tools made from high-speed steel (HSS) and cobalt alloys. Its key advantage is the combination of precise sharpening performance with a compact design and exceptionally simple operation. Thanks to the use of a CBN grinding wheel and a complete set of ER collets, the machine enables fast and accurate drill sharpening without the need for specialized operator skills. It is an optimal solution for workshops, tool rooms, and industrial plants.

Main advantages of the machine
Sharpening of spiral drills from ø2 to ø13 mm with the ability to set the point angle from 90° to 135°.
High-quality CBN (borazon) grinding wheel included – ideal for sharpening high-speed steel (HSS) drills.
Additional port for split-point grinding – improves cutting efficiency and reduces cutting forces.
Simple and intuitive operation – no need for prior operator training.
Compact dimensions and low weight of 9 kg – easy mobility and convenient placement at the workstation.
Complete set of collets and holders included – ready for operation immediately after setup.
Consistent sharpening repeatability – essential for serial production and precision machining.

The CORMAK DG13MD is based on a robust and stable construction designed to reduce vibrations and ensure operator safety. The high-performance 120 W motor, operating at 4800 rpm, provides ideal working conditions even during continuous operation.

The precise drill clamping system using ER collets and guided positioning in the clamping holder enables highly accurate sharpening, resulting in significantly extended tool life. The additional split-point grinding port allows correction of the drill geometry to reduce cutting resistance and improve drilling performance, especially when working with harder materials.

Precision and work efficiency

The CORMAK DG13MD drill sharpener has been designed to provide maximum accuracy in a short time. Thanks to the high-quality CBN grinding wheel, the machine produces a uniform cutting edge with optimal geometry, improving drilling performance, reducing cutting resistance, and minimizing the risk of drill breakage.

The precise tool guidance eliminates errors caused by incorrect manual positioning, ensuring consistent sharpening results every time.

Applications
