DNMG110408-MS US735
Impact Resilience | High-Toughness US735 | MS Anti-Work Hardening Geometry
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 |
| Imperial | DNMG332-MS | 3/8" | 3/16" | 0.0315" (1/32") |
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.

Technical FAQ & Buying Guide
When choosing CNC cutting tools, check the full model code, dimensions, grade and selected variant before ordering. Do not rely on the product image alone.
For carbide inserts, tool holders, drills and end mills, compare the mounting dimensions, connection type and manufacturer's specifications with your holder or machine. If you are unsure, share your existing part number and machining application with us before ordering.
Check the product listing for the selling unit, pack quantity and included components. If it is unclear whether the price is per piece or per pack, or whether a tool body and inserts are sold separately, contact us before purchasing.
Select cutting speed, feed rate and depth of cut using the relevant manufacturer's recommendations for your tool model, workpiece material, machine conditions and coolant method. The same settings are not suitable for every product or application.
