Description

Izvedba:

S spiralnim utorom, s 4 faznimi vodilnimi ploskvami in internimi hladilnimi kanali. Visokozmogljivi svedri za globoke izvrtine nove generacije v HPC-področju. S 135° kotom konice in toleranca rezil h7 za optimalno izdelavo globokih izvrtin. Visoka natančnost prileganja in okroglost izvrtin.

Opomba:

Dolžina spirale LC = L2 + 1,5 × DC.1
Za procesno varno uporabo svedrov za globoke izvrtine 16×D je potrebno predhodno centriranje z art. 121068121121 ali vodilna izvrtina 4×D s svedrom za vodilne izvrtine art.122736. Za globoke izvrtine od 20×D je treba obvezno izdelati vodilno izvrtino do maksimalne globine vrtanja s svedrom za vodilne izvrtine art. 122736. Izdelava vodilne izvrtine povečuje procesno varnost.
