GF-keg-R15-lg-IKZ-SD12-Z4-HA

solid carbide thread milling cutters for tapered threads

Article number GF175911.5785

Machining of tapered internal threads.

Product features and benefits:

Smooth milling operation thanks to flutes with 15° helix angle.
Deep thread possible thanks to long thread part.
Partly across all dimensions.
Cylindrical or preferably tapered pre-drilled tap hole necessary.
Pitch-dependent tool with corrected thread profile.
