CNMG120408-GH US735
Stainless Steel Warrior | US735 Impact Grade | GH Reinforced Edge
Engineered for Impact and Reliability
US735 Grade (The Impact King): The US735 is Mitsubishi's legendary CVD grade for M-Class (Stainless Steel). It is formulated with a specialized substrate that prioritizes fracture toughness over pure hardness. This makes it the only choice for "problem" jobs involving heavy interruptions, scale-covered castings, or machines with less-than-perfect rigidity.
GH Chipbreaker (Structural Strength): The GH geometry is designed for high-load environments. Unlike finishing breakers that have sharp, fragile tips, the GH features a reinforced land (T-land). This increases the strength of the cutting edge, allowing it to plow through work-hardened layers without chipping.
0.8mm (1/32") Universal Radius: The 0.8mm radius is the industry standard for general-purpose roughing, offering a high safety factor against tip breakage while still providing manageable cutting forces.
Metric vs. Imperial Comparison
| System | Model Designation | I.C. (Inscribed Circle) | Thickness | Radius (RE) |
|---|---|---|---|---|
| Metric | CNMG120408-GH | 12.7 mm | 4.76 mm | 0.80 mm |
| Imperial | CNMG432-GH | 1/2" | 3/16" | 0.0315" (1/32") |
Heavy-Duty Cutting Parameters
*US735 is designed for lower speeds and higher feeds compared to PVD grades. Always use abundant coolant.
| Workpiece Material | Speed (Vc) | Feed (fn) | Depth (Ap) |
|---|---|---|---|
| Austenitic Stainless (304/316) | 70 - 140 m/min | 0.15 - 0.40 mm/r | 1.00 - 5.00 mm |
| Duplex Stainless Steel | 50 - 100 m/min | 0.15 - 0.35 mm/r | 1.00 - 4.00 mm |
Recommended Tool Holders
Maximum clamping force is required for heavy roughing. Fits DCLNR/L 12 series holders:

US735 (The Tough Choice): Use this when you are breaking inserts or dealing with heavy vibrations and scale. It is the "safety" grade.
VP15TF (The Precision Choice): Switch to VP15TF for stable, continuous finishing to achieve higher surface quality and faster cutting speeds.

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.
