Spiralgenutet, mit 6 Führungsfasen und internen Kühlkanälen.
Hochleistungs-Pilotbohrer der neuen Generation im HPC-Bereich.
Mit 140°-Spitzenwinkel und spezieller Schneiden- Toleranzp6 zur optimalen Erzeugung einer Pilotbohrung. Hohe Fluchtungsgenauigkeit und Rundheit der Pilotbohrung.

Hinweis:

Spannutenlänge LC = L2 + 1,5 × DC.
Eine Pilotbohrung wird für Tieflochbohrungen ab 16×D empfohlen und ist für Tieflochbohrungen von 20×D bis 30×D zwingend erforderlich. Das Setzen einer Pilotbohrung erhöht immer die Prozesssicherheit.
