- HSS-E Fluteless (Roll Form) Taps.
- Fluteless taps are also referred to as “Roll Form” or “Thread Flow” taps.
- Unlike standard taps, fluteless taps create internal threads by pressure deformation, rather than by material removal.
- As a result, no chips are formed as no material is removed.
- The thread is formed by the tap in the ductile material creating threads that have a smoother surface and greater tensile strength under dynamic stress than cut threads.
- It is essential to use a high quality lubricating fluid when using fluteless taps.
- Materials with a minimum elongation of 5% and a tensile strength no greater than 1,000 N/mm2 are suitable for thread forming.
- Metric Coarse angle of thread is 60 degrees.
- The crest is flat and the thread has clearance at the root allowing external thread and internal thread to engage well.
- Larger root radius and lower thread height enable easy screw thread processing and increase thread screw strength.
- Recommended tapping drill: 7.4mm
