CNMG160612-RM5 WMP20G – Indexable turning insert for stainless steel, Walter Tools

The CNMG160612-RM5 WMP20G is an indexable turning insert engineered for dependable performance when machining stainless steel under medium to robust conditions.

• Tiger·tec Gold coated carbide grade WMP20G
• Optimised RM5 chipbreaker for secure chips
• Rhombic 80° geometry for versatile turning
• 1.2 mm corner radius and 0° negative clearance

Improved process reliability through advanced coating technology

The Tiger·tec Gold coating combined with the WMP20G carbide grade is formulated to support stable cutting in challenging materials such as stainless steel. This coating technology reduces the tendency for built-up edge and helps maintain a sharp cutting zone over extended machining intervals. For production environments where consistent part quality and predictable tool life matter, the coated grade delivers thermal and mechanical resistance that translates into fewer tool changes and reduced process variations. The result is a measurable improvement in machining reliability and repeatability.

Geometry and chip control that enhance productivity

The insert’s rhombic 80° shape and RM5 chipbreaker are designed to balance versatility and secure chip formation. The 80° geometry offers flexible approach angles for a wide range of turning operations, while the RM5 chipbreaker promotes short, controllable chips when machining ductile stainless steels. The 1.2 mm corner radius provides edge strength for interrupted cuts and longer engagement, and the 0° negative clearance creates a stable cutting edge suitable for heavier cut depths. Together, these geometry features reduce vibration, support surface finish targets and help maintain cycle-time efficiency.

Practical advantages on the shop floor and material compatibility

The insert is positioned for applications in the ISO M group and is especially suited to rostfreiem Stahl (stainless steel) where heat and work-hardening tendencies are common. As a coated carbide insert with a clearly defined chip control strategy, it contributes to process security and lower scrap rates in serial production. The tool offers an effective compromise between robustness and finish quality, making it suitable for both roughing and mixed turning tasks where machine time and part consistency are critical.

FAQ

What materials is this insert suitable for?
The CNMG160612-RM5 WMP20G indexable turning insert from Walter Tools is designed primarily for machining stainless steel (ISO M), supporting stable chip formation in these demanding materials.

How does the RM5 chipbreaker affect chip control?
The RM5 chipbreaker on this insert promotes short, controllable chips when turning ductile and work‑hardening stainless steels, improving process security and reducing the risk of entanglement.

Can the insert be used for finishing operations?
Yes, the combination of the rhombic 80° geometry and the 1.2 mm corner radius allows mixed use; the coated grade supports acceptable surface finishes while maintaining edge integrity during longer engagements.

Is the geometry suitable for interrupted cuts?
The 1.2 mm corner radius provides increased edge strength for interrupted cuts, offering greater resistance to edge chipping compared with finer radii.

Which series and coating technology does the insert belong to?
This product is part of the Tiger‑tec Gold series and uses the WMP20G coated carbide grade to improve thermal resistance and wear performance in stainless‑steel turning.
