Recommended Cutting Parameters
Optimized for CNC Lathe operations in stainless and alloy steels:
- Cutting Speed (Vc): 100 - 180 m/min (330 - 590 SFM)
- Feed Rate (f): 0.10 - 0.25 mm/rev (0.004 - 0.010 ipr)
- Depth of Cut (ap): 0.5 - 2.5 mm
*Note: Use high-pressure coolant for best results in gummy stainless steel.
Grade & Coating: US735 CVD Specialist
The US735 grade is a dedicated CVD (Chemical Vapor Deposition) coated carbide designed to combat the intense heat generated during medium turning of stainless steel. The multi-layer coating acts as a thermal barrier, protecting the sub-micron substrate from edge deformation and crater wear.
Optimized Chipbreaker Geometry
With its positive rake angle, the WCMT geometry significantly reduces cutting resistance and vibration. The 0.4mm corner radius provides a balance between edge strength and surface finish, preventing work hardening of the material surface during precision CNC machining.

Questions & Answers
Expert Tip: Carbide Grade Selection
For the best CNC productivity, pair the WCMT06T304 with rigid machine setups. If you are experiencing vibration, reduce the feed rate slightly before lowering the cutting speed to maintain the CVD coating's thermal efficiency.

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.
