CNMG120412-RM5 WMP20G indexable turning insert — Tiger·tec Gold grade (Walter Tools)

A CNMG120412-RM5 WMP20G indexable insert engineered for turning rostfreier Stahl in medium to robust machining conditions, offering stable chip formation and extended tool life.

• Tiger·tec Gold coating for wear resistance
• RM5 chipbreaker for stable chip control
• Rhombic 80° form, 1.2 mm corner radius

Efficient cutting of rostfreier Stahl for predictable productivity

The graded WMP20G coating (Tiger·tec Gold) was developed to handle the specific challenges of rostfreier Stahl: material toughness, a tendency to form built-up edge and elevated cutting temperatures. By combining a coated carbide grade with an optimised chipbreaker, the insert supports stable cutting performance and reduced frequency of tool changes. The result is more predictable cycle times and improved process reliability on stainless turning tasks, which helps to protect both component quality and downstream operations.

Edge robustness and controlled chip behaviour for less downtime

The RM5 chipbreaker promotes controlled chip formation under moderate to heavy cutting parameters, while the 1.2 mm corner radius increases edge strength for interrupted cuts and longer corner life. The 0° relief (negative) geometry enhances cutting stability when rigidity is limited or when heavier engagement is required. Explaining the terms: a larger corner radius trades some surface finish for greater durability, and a negative relief angle shifts cutting forces to favour robustness — both choices that reduce the risk of unexpected edge failure and unplanned stoppages.

Versatile geometry that supports economical turning strategies

The Rhombic 80° shape provides a versatile cutting edge orientation suitable for a range of turning operations and clamping systems. With its specified dimensions and the coated carbide grade, the insert is suited to batch production and single-piece tasks where consistent performance is needed. The indexable format reduces handling time for replacements and simplifies inventory management. If application parameters require verification, Metav Werkzeuge can provide advice on optimum feeds and depths to balance life and surface quality when using this Walter Tools grade.

FAQ

Which materials is this insert intended for?
The CNMG120412-RM5 WMP20G insert is specified for machining rostfreier Stahl and has been graded for medium to robust turning conditions.

What advantage does the Tiger·tec Gold coating provide?
Tiger·tec Gold on the WMP20G grade improves wear resistance and heat management, helping the insert maintain edge integrity during prolonged rostfreier Stahl machining.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker is designed to produce controlled chips and support stable evacuation, which contributes to consistent surface quality and reduced risk of built-up edge.

When is the 1.2 mm corner radius recommended?
A 1.2 mm corner radius offers increased edge strength for interrupted cuts or higher engagement; it is chosen when robustness and longer edge life are priorities over the finest possible surface finish.

Is the negative 0° relief suitable for heavy cuts?
The 0° (negative) relief geometry favours stability and resistance to edge deformation, making it appropriate where rigidity is constrained or more robust cutting is required.
