Synchro machine taps
metric ISO thread DIN 13, for blind holes
CNC/Synchro
2,5xd B (3,5-5)
Universal high performance in the package
The synchronous machine taps are optimised for use on CNC machines. The special geometry with a minimized
thread portion (guiding portion) and very aggressive cutting angle allows the reliable tapping
process in various materials with highest lifetime. Due to the small guiding portion and the extremely free
geometry the tap can be rigidly clamped in a surface chuck.
Advantages of synchro taps:
•universal use in different materials
•for the highest demands from the user on variability
•reduction of the tool costs and variant diversity
•reduction of the cooling agent consumption
•lower capital commitment
•innovative cutting geometry allows shorter cycle times due to higher cutting speeds
•best possible utilization of the potential of the CNC machine
•process-reliable cutting
Execution: structural dimensions according to DIN 371 = reinforced shaft (up to M 10),
DIN 376 = overrun shaft (from M 12).
