Advanced Grade & Chip Control
US735 Grade: This CVD-coated carbide grade is the first choice for interrupted cutting of stainless steel. It features a specialized substrate that absorbs impact and a coating that resists built-up edge (BUE), significantly extending tool life compared to standard inserts.
Finishing Chipbreaker: The VCMT160404 is designed for light-to-medium depths of cut, providing excellent chip curling even at high feed rates, ensuring your CNC machine runs without "bird-nesting."
Technical Cutting Parameters
For optimal performance in stainless steel turning, we recommend the following parameters:
| Workpiece Material | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless (304/316) | 80 - 170 m/min | 0.08 - 0.20 mm/rev | 0.3 - 2.0 mm |
| Alloy Steel | 100 - 200 m/min | 0.10 - 0.25 mm/rev | 0.5 - 2.5 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.
