The VP15TF Miracle Grade
VP15TF is Mitsubishi’s premier AlTiN PVD coating. It is specifically formulated to bridge the gap between high-speed performance and extreme toughness. In stainless steel turning, this coating prevents the work material from work-hardening the edge, extending tool life significantly over standard uncoated or TiN-coated carbides.
MV "Multi-Value" Chipbreaker
The MV chipbreaker geometry is a "medium-finish" design. It provides a wide chip-breaking range, which is critical for larger TPMH16 inserts that may encounter varying depths of cut (DOC) in a single pass. It ensures the operator maintains control over chip flow in deep internal boring holes.
Recommended Cutting Parameters
| Material Group | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Mild / Carbon Steel | 120 - 280 m/min | 0.05 - 0.20 mm/rev | 0.3 - 2.5 mm |
| Stainless Steel (316/304) | 80 - 180 m/min | 0.05 - 0.15 mm/rev | 0.2 - 2.0 mm |
