SNMG120416-RM5 WMP20G WMP20G Wendeplatten - Walter Tools

Combining the Tiger·tec Gold coating with the RM5 chipbreaker and a 1.6 mm corner radius produces a turning insert that sustains stable cutting edges and predictable chip control when machining rostfreier Stahl; order via Metav Werkzeuge or contact our consultants for application-specific recommendations.

SNMG120416-RM5 WMP20G indexable turning insert for rostfreier Stahl, Tiger·tec Gold – Walter Tools

The SNMG120416-RM5 WMP20G is a square indexable turning insert designed for robust, repeatable performance in the machining of rostfreier Stahl, combining a Tiger·tec Gold coating with a tailored RM5 chipbreaker to support secure chip formation under medium to heavy conditions

• Tiger·tec Gold for edge stability and wear resistance
• RM5 chipbreaker optimised for rostfreier Stahl
• Square 90° form with 1.6 mm corner radius
• 0° (negative) relief for interrupted cuts

Consistent performance on rostfreier Stahl for predictable productivity

The combination of the Tiger·tec Gold coating and the WMP20G grade provides a balance between wear resistance and thermal stability, which is critical when machining rostfreier Stahl. Coated carbide substrates reduce the tendency for built-up edge and enable longer cutting intervals, so production can run with fewer tool changes. This results in a measurable productivity gain and lower process variability, a clear rational benefit for shops aiming to improve throughput while maintaining component quality.

Controlled chip formation and reliable cutting-edge life

The RM5 chipbreaker is developed to promote short, controllable chips when turning stainless grades; this reduces evacuation issues and the risk of re-cutting. The 1.6 mm corner radius and square 90° geometry deliver a compromise between strength and surface finish, helping to avoid edge chipping under interrupted or moderately roughing conditions. The 0° (negative) relief angle increases edge robustness for heavy cuts, supporting stable tool life and predictable maintenance intervals.

Practical setup and application advice for efficient integration

For best results, pair the insert with a rigid toolholder and ensure correct seat and clamp torque to maintain repeatability. Moderate cutting speeds with appropriate coolant strategies usually prevent excessive heat build-up on rostfreier Stahl, allowing the coated substrate to perform as intended. When finishing, reduce depth of cut to exploit the insert’s edge integrity for improved surface quality.

FAQ

What materials is this insert intended for?
The SNMG120416-RM5 WMP20G turning insert from Walter Tools is designed primarily for machining rostfreier Stahl (ISO group M) under medium to robust conditions.

How does the RM5 chipbreaker benefit shop processes?
The RM5 chipbreaker on the SNMG120416-RM5 WMP20G promotes short, controlled chips when turning rostfreier Stahl, improving chip evacuation and reducing the risk of interference with the tool or workpiece.

Is the insert suitable for interrupted cuts?
Yes, the 0° (negative) relief and robust geometry of the SNMG120416-RM5 WMP20G increase resistance to edge chipping, making the insert appropriate for interrupted or unstable cut conditions.

What is the effect of the 1.6 mm corner radius?
A 1.6 mm corner radius on the SNMG120416-RM5 WMP20G balances edge strength and surface finish, providing improved tool life during moderate roughing while still allowing acceptable finishing performance.

Can this insert be used for finishing operations?
The SNMG120416-RM5 WMP20G can be used for finishing when parameters are adjusted accordingly—reduce depth of cut and feed to exploit the coated grade’s edge integrity for improved surface quality.
