DNMG110404-FM5 WMP20G indexable turning insert — Tiger·tec Gold, for stainless steels — Walter Tools

The DNMG110404-FM5 WMP20G is a coated carbide turning insert designed for reliable roughing and medium finishing of stainless steels, combining a robust chip control geometry with a fine 0.4 mm nose radius for consistent surface quality.

• Tiger·tec Gold coated grade WMP20G
• Optimised FM5 chipbreaker for stable chips
• Rhombic 55° form for versatile toolholders
• 0.4 mm nose radius for dependable surface finish

Consistent performance on stainless steels for stable production

The Tiger·tec Gold-coated carbide grade delivers a predictable combination of wear resistance and toughness suited to stainless steels, which are prone to work hardening and edge build-up. The coated cutting surface helps to reduce built-up edge and thermal softening, improving tool life under moderate to robust cutting conditions. As a result, process reliability is increased and unplanned tool changes become less frequent, supporting steady machining cycles and higher overall productivity.

Precision geometry for repeatable quality and easy tool set-up

The rhombic 55° geometry and negative 0° relief provide a secure seating in common indexable holders and help maintain cutting stability during interrupted cuts. The 0.4 mm nose radius balances strength and finish capability: larger radii aid tool life, while this radius still enables acceptable surface integrity for many turning tasks. Clear geometry simplifies insert selection and reduces set-up time, helping workshops maintain consistent component tolerances with minimal adjustments.

FM5 chipbreaker and chip control to lower machining risk

The FM5 chipbreaker is engineered to produce short, controllable chips when turning stainless steels, reducing the risk of entanglement and improving swarf evacuation. Controlled chip formation minimises surface damage and protects the cutting edge, which in turn reduces vibration and improves batch-to-batch consistency. For production environments seeking predictable results, the combination of chipbreaker design and coated carbide substrate supports continuous operation and fewer interruptions.

Integration and practical advantages for workshop routines

The ISO designation and standard DNMG form factor make the insert compatible with a wide range of holders and tool systems, allowing straightforward integration into existing tool sets. The coated carbide composition gives a balanced performance for medium-duty applications, while the insert size and thickness adhere to common industrial dimensions for ease of replacement. This reduces inventory complexity and helps planners match tooling to component requirements without extensive requalification.

FAQ

What materials is this insert intended for?
The DNMG110404-FM5 WMP20G insert from Walter Tools is optimised for machining stainless steels, providing controlled chip formation and reduced edge build-up under typical stainless cutting conditions.

What does the WMP20G grade indicate?
WMP20G denotes Walter Tools’ coated carbide grade within the Tiger·tec Gold family; it combines a protective coating with a substrate tuned for toughness and wear resistance suitable for rostfreier Stahl.

How does the FM5 chipbreaker improve machining?
The FM5 chipbreaker creates short, manageable chips and supports stable cut evacuation, which protects the cutting edge and improves surface finish when turning stainless steels with this insert.

Is the insert compatible with standard DNMG toolholders?
Yes — the rhombic 55° form and ISO designation DNMG110404-FM5 allow use in commonly available indexable turning holders designed for DNMG inserts.

What role does the 0.4 mm nose radius play?
The 0.4 mm nose radius offers a compromise between edge strength and surface finish capability, making the insert suitable for a range of roughing to medium-finishing operations.
