DNMG150612-MP5 WPP20G – Indexable turning insert, Tiger·tec Gold, Walter Tools

The DNMG150612-MP5 WPP20G is a rhombic 55° indexable turning insert engineered for productive finishing and medium-turning operations in Stahl, offering a negative 0° rake for stable cuts.

• Tiger·tec Gold coating for extended life
• MP5 chipbreaker optimised for medium cuts
• Rhombic 55° geometry for versatile toolholders
• 0° negative rake for robust cutting stability

Consistent productivity for Stahl machining

The coated carbide grade WPP20G, part of the Tiger·tec Gold series, is formulated specifically for machining Stahl. Designed to handle the typical heat and chip formation of ferrous alloys, the grade balances wear resistance and toughness to provide reliable cutting performance. The combination of the MP5 chipbreaker and the rhombic 55° form reduces chatter tendencies and delivers a controlled chip flow, which simplifies swarf management and shortens cycle times during serial production. Where process stability is critical, this insert maintains dimensional consistency across repetitive passes.

Better chip control and surface quality

The MP5 chipbreaker, developed for medium-depth turning, shapes chips into manageable segments and prevents long stringing swarf. By doing so, surface finish is improved and tool engagement becomes more predictable. The insert’s 0° (negative) rake angle increases shear stability under heavy cuts, which is beneficial when facing interrupted cuts or less rigid set-ups. For customers transitioning from uncoated grades, the coating technology reduces built-up edge and thermal wear, so surface integrity is preserved and downstream finishing operations are reduced.

Robust design for stable tool life

With a 1.2 mm corner radius and the DNMG rhombic profile, the insert supports both finishing and semi-finishing applications without frequent index changes. The coated WPP20G composition provides a wear-resistant layer while retaining a tough substrate; this combination reduces flank wear and maintains edge geometry over longer periods. The insert’s tolerance class M ensures repeatable seating and positioning in standard toolholders, making tool changeover straightforward and helping to minimise setup time in production environments.

Integration and recommended use cases

This insert suits medium- to high-volume turning cells where consistent results and process security are priorities. It is particularly effective for turning unalloyed and alloyed Stahl, as indicated by its grade designation. When combined with appropriate cutting parameters—moderate feed rates and speeds aligned with the grade’s recommendations—the insert delivers predictable tool life and surface finish. For tool presetting and batch programming, the DNMG geometry integrates into common toolholder systems used in CNC lathes, streamlining tool management across the shop floor.

FAQ

What materials is this insert optimised for?
The DNMG150612-MP5 WPP20G is optimised for machining Stahl; the WPP20G grade is formulated to manage the heat and chip formation typical of ferrous alloys.

How does the MP5 chipbreaker affect machining?
The MP5 chipbreaker produces segmented chips for safer evacuation and improved surface quality; in the DNMG150612-MP5 WPP20G it supports predictable cutting in medium-depth turning.

Can this insert be used for roughing and finishing?
With its 1.2 mm corner radius and rhombic 55° geometry, the insert is suitable for both semi-finishing and finishing tasks when toolpath and cutting data are adapted accordingly.

What does the 0° (negative) rake mean for process stability?
A 0° negative rake increases edge strength and reduces the risk of chipping under interrupted cuts, providing greater stability in demanding turning operations using the DNMG150612-MP5 WPP20G.

Where can cutting data and toolholder recommendations be obtained?
Cutting data and holder suggestions for the DNMG150612-MP5 WPP20G are available from Metav Werkzeuge; consultation helps to match speeds, feeds and holder geometry to specific applications.
