technika wiercenia

The Goliath head for drilling holes with undercut and Permanent Rotation System guarantees the highest quality of holes.

Apart from standard rotation, Goliath head spindle also makes a circle. When drilling, the spindle forms a cylindrical hole by making a circle with minimum radius (A). A rotation radius is increased up to 1.50 mm (B) to form an undercut. The process provides high drilling speed and long service life of tools.

All process parameters (speed, time, undercut radius etc.) can be modified.
