DNMG110412-RM5 WMP20G – turning insert, Tiger·tec Gold for stainless steel | Walter Tools

The DNMG110412-RM5 WMP20G is a precision indexable turning insert engineered for reliable performance in demanding stainless steel turning applications, featuring a robust geometry and a Tiger·tec Gold coating for consistent chip control

• Tiger·tec Gold coated carbide for durability
• Optimised for stainless steel (ISO group M)
• 0° negative rake for robust cutting action
• 1.2 mm corner radius for enhanced edge strength

Consistent metal removal and economical productivity

The combination of the Tiger·tec Gold coating and a coated carbide substrate delivers a balance of wear resistance and toughness that helps to maintain a stable cutting edge under the heat and adhesion challenges of stainless steel machining. The dedicated chip control geometry, identified here as RM5, supports regular chip segmentation and evacuation, reducing the risk of built-up edge and unplanned interrupts. For production environments seeking steady cycle times, this insert offers a repeatable performance profile that contributes to process reliability and lower per-part tool costs.

Geometry designed for demanding turning tasks

The rhombic 55° shape provides versatile approach angles for a wide range of external turning operations, while the 1.2 mm corner radius increases the insert’s resistance to chipping during interrupted cuts and heavy depth-of-cut operations. The 0° negative rake (negative geometry) is chosen to enhance insert strength and to tolerate harder cutting conditions; this results in safer, more predictable behaviour when forces peak. Together, these features make the insert suitable for moderate to robust cutting parameters where edge security and predictable wear progression are priorities.

Practical integration and machining benefits

As an indexable insert in the DNMG family, the part is compatible with standard DNMG toolholders that accept a 55° rhombic geometry, enabling straightforward installation and repeatable clamping accuracy. The RM5 chipbreaker reduces manual rework by improving surface finish consistency and chip formation when machining materials in ISO group M. Given the insert’s engineered balance of toughness and coating technology, planners can expect fewer insert changes and a more uniform surface quality across batch runs, supporting stable production and efficient tool management.

FAQ

What materials is this insert suitable for?
The DNMG110412-RM5 WMP20G insert from Walter Tools is designed primarily for stainless steel (ISO group M) and performs best where secure chip formation is required.

How does the Tiger·tec Gold grade benefit machining?
The Tiger·tec Gold coating used on the DNMG110412-RM5 improves wear resistance and thermal stability, helping to extend edge life and maintain consistent cutting performance in stainless steel turning.

What advantage does the RM5 chipbreaker provide?
The RM5 chipbreaker supports controlled chip formation and evacuation, which reduces built-up edge and contributes to a more consistent surface finish with the Walter Tools turning insert.

Why choose a 0° negative rake geometry for turning?
A 0° negative rake increases insert strength and resistance to mechanical shock, making the DNMG110412-RM5 WMP20G suitable for heavier cuts and applications with fluctuating cutting forces.

How does the 1.2 mm corner radius affect tool life and finish?
The 1.2 mm corner radius enhances edge robustness against chipping and helps maintain a favourable balance between tool life and achievable surface quality when machining tough materials.
