DNMG150608-MM5 WMP20G indexable turning insert — Tiger·tec Gold, for stainless steel (ISO M) — Walter Tools

DNMG150608-MM5 WMP20G is a rhombic 55° indexable turning insert designed for reliable finishing and medium-duty turning of stainless steel components in industrial production.

• Tiger·tec Gold coating for longer tool life
• Optimised MM5 chipbreaker for stable chip control
• Rhombic 55° geometry for versatile turning
• Suitable for stainless steels (ISO group M)

High-performance coating and predictable tool life

The combination of the Tiger·tec Gold coating and a coated carbide substrate ensures a balance between wear resistance and edge toughness. This insert is engineered to reduce flank wear under the demands of machining stainless steel, materials known for high heat generation and built-up edge formation. The result is more consistent component tolerances and reduced rework. The coating technology supports elevated cutting temperatures and contributes to a longer service life, which lowers tool-change frequency and enhances overall process efficiency.

Engineered chip control for stable machining

Equipped with the MM5 chipbreaker, the insert promotes steady, compact chips even in difficult-to-machine grades. Stable chips reduce the risk of entanglement and help maintain machine uptime, which is especially important in automated turning operations. The chipbreaker geometry is matched to the rhombic platform and the 0° rake (negative) setting to encourage controlled shear and avoid erratic cutting forces, thereby supporting predictable cycle times and improved surface integrity on each workpiece.

Geometry and edge preparation for versatile usage

The rhombic 55° form and 0.8 mm corner radius provide a versatile cutting edge suitable for both light finishing cuts and moderate profiling tasks. The negative rake angle contributes to a robust cutting edge that resists chipping during interrupted cuts or when handling tougher stainless steel alloys. Because of that robust edge preparation and the insert’s balanced geometry, this grade is appropriate for shops seeking reliable repeatability across small-batch and series production, delivering consistent surface quality with minimal adjustment of cutting parameters.

FAQ

What workpiece materials suit this insert best?
The DNMG150608-MM5 WMP20G insert is specifically designed for stainless steel (ISO group M), providing stable chip formation and wear resistance under the tougher cutting conditions these alloys present.

How does the MM5 chipbreaker affect machining?
The MM5 chipbreaker promotes compact, controllable chips and consistent cutting forces, which improves surface finish and reduces the likelihood of chip-related interruptions when machining stainless steels.

Is the negative 0° rake suitable for interrupted cuts?
Yes. The 0° (negative) rake produces a stronger cutting edge that resists chipping in interrupted or unstable cuts, making the insert suitable for mixed turning tasks in production environments.

Can the insert be used for both finishing and profiling?
The rhombic 55° geometry combined with a 0.8 mm radius allows flexible use from light finishing to moderate profiling, offering a compromise between sharpness and edge robustness.

Which series and grade does this insert belong to?
This insert is part of the Tiger-tec Gold series and uses the WMP20G grade, developed for reliable performance on stainless steel with good edge stability.
