Beschreibung
Esecuzione:
Robusto nocciolo ed affilatura speciale − tagliente trasversale di elevata precisione di centratura. 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 ⌀ di 3,8 mm. Fino a ⌀ di 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.
Attenzione:
Dimensioni terminanti in X = tolleranza ⌀ tagliente h7.
Nota:
Lunghezza scanalatura per trucioli LC = L2 + 1,5 × DC.
