CYCLUS TOOLS Head tube milling cutter | ZS 66 (66 mm, 14.7 mm, 45° - ZS) | milling head single, suitable for 720211.
With the head tube cutter you can prepare head tubes with an inner diameter of 44 mm and a milling depth of 8.2 mm for the headset assembly of a semi-integrated headset. The angle of the bearing shell seats is 45°. The cutter produces precise flat and coaxial head tube seats.
The new naming system (S.H.I.S. - Standardised Headset Identification System) was used to name the individual cutters. It consists of the type of headset and the corresponding inner diameter of the head tube (e.g. EC 34). EC (External Cup) stands for the classic headset, ZS (Zero Stack) for the semi-integrated headset and IS (Integrated Standard) for the integrated headset.
