CNMG190612-RP5 WPP05G indexable turning insert by Walter Tools — Tiger·tec Gold, for Stahl

The CNMG190612-RP5 WPP05G is an indexable turning insert designed for reliable finishing and semi-finishing of Stahl components, combining a Tiger·tec Gold coated carbide grade with an RP5 chipbreaker for controlled chip formation.

• Tiger·tec Gold coated carbide grade WPP05G
• Optimised RP5 chipbreaker for consistent chips
• Rhombic 80° geometry for versatile turning
• 1.2 mm corner radius for stable edge life

Consistent surface quality through advanced coating and grade selection

The combination of the Tiger·tec Gold coating and the grade WPP05G delivers a balance between wear resistance and toughness, which stabilises cutting in typical Stahl turning operations. The coated carbide resists abrasive wear while the substrate toughness reduces edge chipping; this results in more predictable tool life and a better surface finish on the workpiece. For users seeking repeatable results in batch production, the coated grade reduces the need for frequent tool changes and supports consistent dimensional accuracy.

Geometry and chip control that reduce machining variability

The rhombic 80° insert shape together with the RP5 chipbreaker promotes effective chip formation and evacuation in Stahl machining. The negative 0° free angle provides a stable cutting edge under varying cutting forces, while the 1.2 mm corner radius improves edge strength, reducing the likelihood of microchipping during interrupted cuts. These geometric features mean fewer process interruptions and reduced scrap rates, particularly in moderate depth-of-cut finishing applications.

Practical productivity gains from a robust insert design

The indexable design of the CNMG insert enables quick indexing and replacement, which minimises machine downtime and improves shop-floor throughput. The combination of the TIGER·tec Gold technology and the RP5 chip control contributes to longer intervals between tool changes, supporting higher overall equipment effectiveness. For customers processing medium to high volumes of Stahl components, this insert offers a pragmatic route to higher productivity without complex process adjustments.

Application guidance and process fit

This insert is tailored to Stahl group materials and performs best in turning operations where a controlled chip shape and robust edge are priorities. Use the rhombic 80° geometry for external turning and profiling where versatility is required; the RP5 chipbreaker is suited to producing short to medium chips at typical finishing and semi-finishing cutting parameters. When selecting cutting speeds and feeds, favour stable clamping and consistent coolant application to make the most of the coated grade’s wear resistance.

FAQ

What materials is this insert suitable for?
This insert is specified for Stahl materials; the WPP05G grade and Tiger·tec Gold coating are optimised for the thermal and chip-formation behaviour of Stahl.

How does the RP5 chipbreaker affect machining?
The RP5 chipbreaker on the CNMG190612-RP5 WPP05G promotes predictable chip shapes and improved evacuation in Stahl turning, reducing the risk of chip-related interruptions.

What benefits does the 1.2 mm corner radius provide?
A 1.2 mm corner radius increases edge strength and helps prevent microchipping under varying cutting loads, supporting longer tool life and consistent surface quality.

Is this insert suitable for finishing and semi-finishing?
Yes—this insert’s geometry, coated grade and chip control make it well suited to finishing and semi-finishing turning operations in Stahl.

Can the insert be indexed during production to save time?
The indexable design of the CNMG190612-RP5 enables quick indexing to a fresh cutting edge, reducing machine downtime and simplifying tool management.
