Dominate Difficult Stainless Steel Cuts
US735 Grade (The Impact Master): The US735 grade is Mitsubishi’s definitive answer to Interrupted Cuts. It features a high-toughness carbide substrate paired with a specialized PVD coating. This combination is designed to absorb the mechanical shock of hitting keyways, holes, or hex-corners in Stainless Steel without the edge cracking or "chipping out" like harder CVD grades.
MS Chipbreaker (The Stainless Specialist): The MS (Medium-Sharp) geometry is more aggressive than the standard MA. It features a sharper cutting edge and a specific rake profile designed to slice through gummy materials. This significantly reduces Work Hardening—a common failure point when machining 304 or 316 stainless steel.
0.8mm Radius (Structural Integrity): The "08" (1/32") radius provides a robust cutting tip. For 11-size inserts, this radius ensures the edge stays intact under higher feed rates and during semi-roughing passes on uneven workpiece surfaces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG110408-MS | 9.525 mm | 4.76 mm | 0.80 mm |

Recommended Cutting Parameters
*US735 performs best at moderate speeds where edge toughness is critical.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 50 - 120 m/min | 0.10 - 0.28 mm/r | 0.50 - 2.50 mm |
| Tough Alloy Steels | 60 - 140 m/min | 0.12 - 0.30 mm/r | 0.80 - 3.00 mm |

Shop DDJNR 11 HoldersPro-Tip: US735 vs. VP15TF
US735 (The Interrupted Specialist): Use this when your lathe setup isn't perfectly rigid, or when you are cutting parts with holes or hex corners. It prevents catastrophic edge failure.
VP15TF (The Continuous Speedster): Switch to VP15TF for clean, continuous CNC turning at higher RPMs. It offers better wear resistance but is more likely to crack under heavy impact.
