US735 Toughness Grade
As a premium CVD turning insert, the US735 grade is Mitsubishi's go-to for interrupted cuts. It prevents thermal cracking and is highly effective at resisting built-up edge (BUE) in gummy materials, making it a reliable long-tail precision tool.
ES Finish-Cut Breaker
The ES chipbreaker features a high rake angle specifically for fine finishing. It minimizes cutting forces and heat buildup, which is critical when machining long-tail industrial tools to tight tolerances without deformation.
Recommended Cutting Parameters
| Material | Speed ($v_c$) | Feed ($f$) | DOC ($a_p$) |
|---|---|---|---|
| Stainless Steel (304/316) | 60 - 150 m/min | 0.05 - 0.18 mm/rev | 0.2 - 1.5 mm |

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.
