|---|---|
| Thread Standard / Angle | ISO Metric 60° (Full Form) |
| Thread Pitch | 1.0 mm |
| Insert Size (IC) | 6.35 mm (1/4") |
| Grade / Coating | VP15TF (Miracle PVD Coated) |
VP15TF Miracle Grade
The VP15TF grade is a micro-grain carbide substrate paired with the "Miracle" (Al-Ti-N) PVD coating. This combination offers high fracture resistance during interrupted cuts and excellent adhesion resistance. It is widely regarded as a universal grade for indexable threading where stability and edge longevity are required.
-S Type 3D Chipbreaker
The -S (3D) chipbreaker is designed to solve the common problem of long, stringy chips in internal threading. By forcing chip deformation, it prevents chip entanglement around the workpiece and the boring bar, ensuring a safer process and preventing surface damage on finished threads.
