CNMG160612-RM5 WMP20S turning insert – Tiger·tec Silver, for rostfreier Stahl (Walter Tools)

CNMG160612-RM5 WMP20S is a precision turning insert designed for reliable machining of rostfreier Stahl in medium to robust conditions

• Tiger·tec Silver coating for durable edge
• Optimised RM5 chipbreaker for secure chips
• Rhombic 80° form, 1.2 mm corner radius
• Negative 0° free rake for robust turning

Consistent performance on rostfreier Stahl through specialised grade and coating

The combination of the WMP20S grade with the Tiger·tec Silver coating provides a balance between wear resistance and thermal stability tailored to the demands of rostfreier Stahl. Coated carbide supports stable chip formation and reduces the tendency for built-up edge, which is typical when turning tough, heat-generating stainless workpieces. This engineered grade is aimed at operations requiring repeatable results under moderate to heavy cutting conditions, helping to maintain surface finish and dimensional control over longer tool life.

Geometry optimised for chip control and process security

The rhombic 80° plate form, together with the RM5 chipbreaker and a 1.2 mm corner radius, delivers predictable chip flow and strength at the cutting edge. The negative 0° free rake angle increases edge support and resistance to chipping when facing interrupted cuts or harder zones in workpieces. These geometry choices translate into fewer tool changes, reduced vibration sensitivity and stable cutting behaviour—advantages that directly affect cycle times and overall shop-floor throughput.

Designed for productivity and repeatable results

Tolerance class M and the solid construction ensure repeatable positioning and reliable clamping in standard toolholders. The coated grade is developed to offer a good compromise between wear resistance and edge toughness, extending effective tool life in serial production. Together, coating technology and robust geometry contribute to process reliability and predictable regrind intervals, supporting leaner tool management and improved uptime on the turning centre.

Typical applications and practical machining guidance

This insert is intended primarily for turning operations on rostfreier Stahl, especially where material toughness and heat generation demand a coating that controls adhesion and wear. The insert’s shape and chipbreaker suit medium to robust cutting parameters; adjustments to feed and coolant strategy can further enhance chip breaking and surface quality. For specific machining windows, holder selection and cutting data tailored to the workpiece and machine are recommended to maximise the grade’s potential and secure consistent production results.

FAQ

What workpieces is this insert best suited for? This turning insert is optimised for machining rostfreier Stahl; the WMP20S grade and Tiger·tec Silver coating provide improved chip control and resistance to built-up edge when turning stainless components.

How does the RM5 chipbreaker influence machining? The RM5 chipbreaker on the CNMG160612-RM5 WMP20S promotes reliable chip formation and evacuation, reducing the risk of entangling chips and supporting consistent surface quality in medium to robust turning operations.

Is the geometry suitable for interrupted cuts? Yes, the negative 0° free rake and robust rhombic 80° form with a 1.2 mm corner radius give the insert enhanced edge support, making it more resistant to chipping during interrupted cuts.

Can this insert be used for finishing as well as roughing? The CNMG geometry and the chosen corner radius favour strength and durability; with adjusted feeds and speeds the insert can be used for both medium finishing and roughing on rostfreier Stahl, depending on surface quality requirements.
