Description

Esecuzione:

I taglienti principali diritti e un profilo speciale delle scanalature assicurano un'ottima evacuazione dei trucioli. La robusta geometria del tagliente garantisce una foratura sicura e ad alte prestazioni.
Vastissime possibilità di impiego sugli acciai grazie alla combinazione di metallo duro tenace a grana ultrafine e rivestimento molto resistente all'usura.

Nota:

Lunghezza scanalatura per trucioli LC = L2 + 1,5 × DC.
