CNMM120412-HU3 WPP10G Drehwendeschneidplatte — turning indexable insert, Tiger·tec Gold coating, for Stahl (Walter Tools)

The CNMM120412-HU3 WPP10G is a rhombic 80° turning indexable insert designed for general-purpose and demanding Stahl machining, combining a Tiger·tec Gold coated carbide grade with an HU3 chipbreaker for controlled chip formation.

• Tiger·tec Gold for extended tool life
• HU3 chipbreaker optimised for Stahl
• Rhombic 80° form with 1.2 mm radius
• 0° (negative) free angle for heavy cutting

Increased productivity through proven coating technology

The coated carbide grade from the Tiger·tec Gold family delivers a balanced combination of wear resistance and toughness. This results in longer tool life under typical turning conditions and reduces the number of tool changes per shift, which increases uptime and throughput. The WPP10G chemistry is tuned for a broad range of Stahl types, addressing both abrasive and adhesive wear modes; the consequence is predictable performance and fewer unexpected interruptions in production. Emphasising process efficiency, the coated grade supports stable cutting at elevated speeds while maintaining surface finish quality.

Reliable chip control and stable cutting geometry

Built around the HU3 chipbreaker and a rhombic 80° shape, the insert provides consistent chip formation in longitudinal turning and medium-depth cuts. The 1.2 mm corner radius improves edge strength for interrupted cuts and supports dimensional stability when machining tougher Stahl grades. The 0° (negative) free angle is suited to more robust set-ups and heavy-duty cuts, giving rigidity and vibration damping where needed. Together these features mean fewer rejected parts and less scrap, translating into measurable cost savings across production runs.

Practical handling, mounting and application benefits

The insert’s nominal size and the standard CNMM contour enable straightforward seat and clamp mounting in many common turning toolholders. The coated surface reduces built-up edge tendencies on typical Stahl workpieces, improving part finish and extending cycle lengths. For shops seeking a versatile, general-purpose insert that handles a variety of turning tasks without frequent re-grading, this option simplifies inventory and tool management. Technical data is compatible with ISO-based tooling systems, easing specification and replacement.

FAQ

What materials is this insert suitable for?
The CNMM120412-HU3 WPP10G from Walter Tools is qualified for machining Stahl (ISO group P), covering a spectrum from more wear-resistant to tougher Stahl subgroups.

How does the HU3 chipbreaker influence performance?
The HU3 chipbreaker on the insert promotes controlled chip segmentation and evacuation when turning Stahl, which supports consistent surface finish and reduces the risk of chip-related interruptions.

Can this insert be used for heavy roughing cuts?
Yes. The negative 0° free angle combined with the 1.2 mm corner radius provides the rigidity and edge strength required for demanding roughing operations with the CNMM120412-HU3 WPP10G insert.

Is the coating suitable for higher cutting speeds?
The Tiger·tec Gold coating technology on the WPP10G grade is designed to offer enhanced wear resistance and thermal stability, enabling higher cutting speeds compared with uncoated grades under appropriate conditions.

Which toolholders are compatible with this insert form?
The rhombic 80° form and CNMM contour match common ISO-style turning toolholders; ensure the correct clamp and seat geometry are used for secure mounting and repeatable positioning.
