Grade: US735 (Stainless Specialist)
The US735 grade utilizes a robust CVD coating technology. This multi-layered coating is designed to resist thermal cracking and flank wear often encountered when turning gummy materials like 316 stainless steel. It is particularly effective for interrupted cuts where edge strength is paramount.
Geometry: Positive Chip Control
The WCMT geometry provides a positive rake angle that lowers cutting resistance. This is vital for small-part machining or when using low-power CNC lathes, as it ensures clean chip breaking and prevents work hardening of the stainless steel surface.
Recommended Cutting Parameters
For optimized tool life and surface finish, follow these general guidelines:
- Cutting Speed (Vc): 80 - 150 m/min (Stainless) | 100 - 180 m/min (Alloy Steel)
- Feed Rate (f): 0.03 - 0.12 mm/rev
- Depth of Cut (ap): 0.2 - 1.5 mm
*Adjust parameters based on the specific grade of stainless steel and machine stability.

Frequently Asked Questions
Q: Is WCMT020102 better for roughing or finishing?
A: With a 0.2mm nose radius, this insert is specifically designed for finishing to light-medium turning. For heavy roughing, a larger radius is recommended.
Q: Can I use this for dry cutting?
A: While US735 has good heat resistance, we recommend using coolant when machining stainless steel to prevent work hardening and improve chip evacuation.
Q: Will this fit my standard boring bar?
A: Yes, as long as your holder is designed for WCMT 02 size inserts (typically used in 6mm to 10mm shank boring bars).
Material Tip: Grade Selection
For continuous cutting in stable conditions, VP15TF is often preferred. However, if you face interrupted cuts or unstable conditions in stainless steel, US735 is the superior choice due to its enhanced toughness and shock resistance.
