DNMG150612‑RM5 WMP20S Turning insert — Tiger‑tec Silver, for stainless steel (Walter Tools)

The DNMG150612‑RM5 WMP20S is a rhombic‑55° indexable turning insert with negative geometry, designed for medium to robust conditions in stainless steel machining and optimised for secure chip formation and repeatable results.

Tiger‑tec Silver coated carbide Optimised for stainless steel (ISO M) Rhombic 55° shape, 1.2 mm corner radius Negative 0° rake for secure cutting

Consistent performance for stainless machining

The coated carbide composition of this insert, supplied in the WMP20S grade and finished with Tiger‑tec Silver, is engineered to handle the specific challenges of stainless steel — such as high toughness, tendency to build up material on the edge and elevated cutting temperatures. The coating improves thermal resistance and wear behaviour, which in turn helps to maintain a stable cutting edge over longer cycles. For production environments where repeatable surface quality and predictable tool life matter, this configuration reduces downtime for insert changes and supports a smoother machining rhythm.

Geometry and chip control that reduce rework

The Rhombus 55° form and the integrated RM5 chipbreaker combine to produce controllable chip shapes during turning operations. The 1.2 mm corner radius and the negative 0° (negative) relief contribute to a secure cutting action that resists deformation of the cutting edge under intermittent loads. These design choices result in fewer built‑up edges and improved surface integrity on machined parts, lowering the risk of subsequent rework and increasing first‑pass yield in batch production.

Process reliability and tool selection made simple

Selecting this indexable insert for stainless steel applications provides an efficient balance between edge robustness and cutting economy. The coated carbide grade is suited to medium and tougher cutting conditions, delivering process security and consistent results across comparable operations. When pairing the insert with an appropriate toolholder and optimised cutting data, the system supports higher productivity with predictable insert change intervals, making it a practical choice for job shops and production lines alike.

FAQ

What materials is this insert suitable for?
The DNMG150612‑RM5 WMP20S is optimised for stainless steel (ISO M); the WMP20S grade supports safe chip formation and stable cutting edges under medium to robust conditions.

How does the RM5 chipbreaker affect machining?
The RM5 chipbreaker on this insert promotes predictable chip control and reduces the likelihood of long, stringy chips when turning stainless steel, improving process reliability and surface finish.

Can this insert be used in light finishing operations?
Yes, the rhombic 55° geometry with a 1.2 mm corner radius provides a balance between strength and finish; paired with appropriate feeds and speeds, it can achieve good surface quality while maintaining edge life.

Is special tooling required for the negative 0° rake?
No specialised holder is required, but toolholders must be compatible with DNMG‑style inserts and correctly set up to exploit the negative geometry for secure cutting performance.

What production benefits does the Tiger‑tec Silver coating bring?
The Tiger‑tec Silver coating enhances thermal resistance and wear behaviour of the coated carbide grade, which helps to extend edge life and support more consistent cutting performance in stainless steel applications.
