VCMT160408‑MM4 WMP20G – indexable turning insert, Tiger‑tec Gold, Walter Tools

The VCMT160408‑MM4 WMP20G insert is a coated carbide tool for dependable turning applications, optimised for machining stainless steel under medium to robust cutting conditions

• Tiger‑tec Gold coated carbide grade
• Optimised MM4 chipbreaker
• 0.8 mm corner radius for durability
• 7° relief angle for secure engagement

Increase throughput with stable chip formation and edge life

The Tiger‑tec Gold WMP20G grade is engineered to maintain a stable cutting edge during the elevated temperatures and adhesive tendencies typical of stainless steel machining. The combination of a coated carbide substrate and the MM4 chipbreaker supports predictable chip flow, which reduces unexpected interruptions and improves cycle times. By choosing a cutting grade tailored for friction and heat management, shops benefit from fewer insert changes and a lower cost per component, while process planners gain reproducible results across series production.

Consistent geometry for repeatable surface quality

A Rhombic 35° insert form with a 0.8 mm corner radius and 7° clearance angle delivers a balanced interaction between strength and cutting engagement. The modest corner radius helps absorb cutting forces in tougher stainless grades without sacrificing surface finish, and the positive relief reduces rubbing and workpiece distortion. These geometric choices mean less rework and a more stable tool life curve, which supports predictable setup intervals and consistent component tolerances in batch production.

Application-focused design that reduces machining risk

Designed specifically for ISO group M applications, this turning insert performs well in medium to robust cutting conditions where built‑up edge and thermal load present challenges. The coated Tiger‑tec Gold surface enhances wear resistance and eases chip evacuation; the result is improved process security and a finish that often removes the need for additional secondary operations. For production environments seeking to balance productivity with repeatability, this insert offers a pragmatic combination of tool life and machining quality, backed by Walter Tools' development for tough stainless grades.
