Description

Esecuzione:

Nocciolo robusto e affilatura speciale, il tagliente trasversale garantisce un'elevata precisione di centraggio. Elevata precisione di allineamento e rotondità del foro grazie ai 4 biselli. Straordinaria evacuazione del truciolo grazie ai 4 canalini interni per il lubrorefrigerante a partire da ⌀ 3,8 mm. Fino a ⌀ 3,7 mm con 2 canalini interni per il lubrorefrigerante. I taglienti principali diritti, con spigoli arrotondati, e la forma delle scanalature producono trucioli corti, anche con materiali che solitamente producono trucioli lunghi.

Nota:

Lunghezza scanalatura per trucioli LC = L2 + 1,5 × DC.
Per l’uso sicuro delle punte 12×D è necessario il precedente centraggio con n. art. 121068 - 121130.
Forme HB e HE disponibili allo stesso prezzo di HA.
Forma HB: ordinare con n. art. 123214.
Forma HE: ordinare con n. art. 123212 + 129100HE.
