| Thread Standard / Angle | ISO Metric 60° (Full Form) |
| Thread Pitch | 1.0 mm |
| Insert Size (IC) | 9.525 mm (3/8") |
| Grade / Coating | VP15TF (Miracle PVD Coated) |
VP15TF Miracle Grade
The VP15TF grade is Mitsubishi’s premier PVD-coated carbide. Utilizing the Al-Ti-N Miracle coating technology, it offers superior resistance to built-up edge (BUE) and thermal cracking. This grade is the industry standard for indexable threading where versatility and high-speed stability are required.
-S Type 3D Chipbreaker
The -S type geometry features a molded 3D chip groove that forces chips to curl and break even at low feed rates common in threading. In CNC threading, this eliminates long, stringy chips that can wrap around the workpiece, ensuring a perfect thread surface finish and protecting your threading tool holder.
