WALTER BCMT160530R-G55 WKP35S Milling Insert (10 pcs)
The WALTER BCMT160530R-G55 WKP35S is a high-performance rhombic (parallelogram) positive-rake \ milling insert. Manufactured in Walter’s Tiger·tec® Silver grade, this insert delivers a reliable balance of toughness, \ wear resistance, and thermal stability — making it ideal for machining steel and stainless steel under moderate cutting conditions.
Material Grade & Coating – WKP35S
- The WKP35S grade is part of Walter’s Tiger·tec® Silver family, featuring a CVD TiCN + Al₂O₃ + TiCN multilayer coating.
- The Al₂O₃ layer protects under high thermal load, while the TiCN layers provide hardness and abrasion resistance.
- A silver wear-indicator layer enables easy visual monitoring of flank wear.
- Compatible with ISO material groups: P (steel), M (stainless), and S (heat-resistant alloys).

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
