Description

Ausführung:

HOLEX Pro Steel:
Gerade Hauptschneiden
und ein spezielles Nutenprofil sorgen für eine gute Spanabfuhr. Die robuste Schneidengeometrie gewährleistet prozesssicheres Hochleistungsbohren. Umfangreiche Anwendungsmöglichkeiten in Stahlwerkstoffen durch eine Kombination aus zähen Ultrafeinkorn-Hartmetall und äußerst verschleißfester Beschichtung.

Hinweis:

Spannutenlänge LC = L2 + 1,5 × DC.
Zum prozesssicheren Einsatz der Bohrer 12×D ist eine vorherige Zentrierung mit NC-Anbohrer Nr. 121068 - 121130 oder HOLEX Pro Steel Nr. 122501 erforderlich.
