DNMG150412-MS US735
Maximum Edge Strength | Anti-Work Hardening | Impact Resistant US735
Designed for High-Feed Reliability
The DNMG150412-MS US735 is the definitive choice for machinists facing unstable turning conditions. If you are searching for a Mitsubishi DNMG150412-MS price that provides long-term ROI, this insert delivers by eliminating catastrophic failures during heavy interrupted cuts on 304 and 316 stainless steel.
US735 Grade (High-Toughness PVD): This is Mitsubishi’s premier PVD-coated grade for tough machining. The US735 grade features a specialized substrate that absorbs vibration and mechanical shock. It is highly resistant to thermal cracking, making it the best PVD coated insert for tough materials like stainless steel and high-temperature alloys.
MS Chipbreaker (Anti-Work Hardening): The MS geometry is a medium-sharp design. Unlike blunt roughing geometries, the MS slices the chip to prevent work hardening in stainless steel. This keeps the material soft for the next pass, extending the life of both your roughing and finishing tools.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | DNMG150412-MS | 12.70 mm | 4.76 mm | 1.20 mm |
| Imperial | DNMG433-MS | 1/2" | 3/16" | 0.0472" (3/64") |
Recommended Cutting Parameters
*The 1.2mm radius supports aggressive feeds. Lower the speed (Vc) for heavy interruptions to maximize toughness.
| Material Group | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| 304/316 Stainless Steel | 60 - 120 m/min | 0.20 - 0.45 mm/r | 1.20 - 4.00 mm |
| Alloy Steels (High-Hardness) | 70 - 140 m/min | 0.25 - 0.50 mm/r | 1.50 - 4.50 mm |

US735 (The Impact Specialist): Mandatory for roughing passes on hex bar, parts with cross-holes, or uneven castings. It prevents the 1.2mm radius from micro-chipping under high-impact.
VP15TF (The Wear Resistant Expert): Switch to VP15TF for continuous CNC turning where high-speed tool life is more important than impact resistance. For most heavy-duty job shop work, US735 is the safer, more reliable grade.
