carbide thread milling cutter, | Emuge-Franken Website

Machining tapered internal thread

Product features and benefits:

Smooth milling thanks to flutes with 15° helix angle
deep threads possible thanks to long thread part
Partly for several dimensions
cylindrical or better tapered pre-drilled tap hole necessary
tool for a specific pitch with corrected thread profile
