GF-R30-lg-IKZ-HB-TiCN

solid carbide thread milling cutters for internal threads

Article number GF162326.9587

Machining of internal thread

Product features and benefits:

Deep threads possible thanks to long milling part
smooth milling thanks to flutes with 30° helix angle
pre-drilled taphole necessary
for a specific pitch
for several dimensions
cutter diam should be smaller 2/3 respect. 3/4 than thread diam.
