Hollow drill with centering on shank

The diamond hollow drills on shank are characterized by long tool life and fast drilling progress. They are equipped as standard with ejection slots and a segmented coating for effective dust ejection. All electroplated drills are also equipped with a center drill for precise spot drilling. The 6-edge clamping shank serves as a reliable receptacle for all drilling machine chucks and for CNC machining centers.

Optionally, our electroplated drills can also be equipped with an ejector spring.

Always the appropriate diameter: In addition to our many standard drills, we also manufacture galvano drills in millimeter increments on customer request, such as Ø62mm and Ø116mm (Fig. 4).
