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 partPartly for several dimensionscylindrical or better tapered pre-drilled tap hole necessarytool for a specific pitch with corrected thread profile
