SNMM250916-HU3 WPP20G indexable turning insert — Tiger·tec Gold coating, 0° negative rake, 1.6 mm corner radius | Walter Tools

A SNMM250916-HU3 WPP20G indexable turning insert engineered for steel (ISO P) applications, offering a coated carbide grade that balances wear resistance and toughness for productive turning operations.

• Tiger·tec Gold coated grade WPP20G
• Suitable for steel (ISO P) machining
• 0° negative rake for robust cutting
• 1.6 mm corner radius for consistent chip control

Consistent performance from a modern coated grade

The Tiger·tec Gold WPP20G grade combines a hard, wear-resistant outer coating with a tough carbide substrate to deliver predictable tool life and stable chip formation when machining steels. This coated carbide formulation is optimised to resist flank and crater wear under typical heat and pressure conditions encountered in turning; the result is improved process reliability and fewer unscheduled tool changes. The specification is targeted at general-purpose steel machining, offering an appropriate compromise between economy and performance.

Reliable edge integrity and chip control for turning

With the HU3 chipbreaker and a 1.6 mm corner radius, the insert provides controlled chip segmentation and a dependable cutting edge for a range of feed rates. The 0° negative rake creates a robust cutting geometry that reduces the risk of edge chipping in interrupted cuts and heavy-duty operations. These features translate into longer intervals between indexings and a steadier surface finish on the workpiece, supporting higher effective productivity on lathe centres.

Designed for process security and repeatability

The square 90° form and tolerance class M ensure consistent seating and repeatable orientation in rigid toolholders, supporting stable machining parameters and reduced set-up variance. Built for steel (ISO P) materials, the insert helps maintain cycle-time consistency and lowers the risk of unexpected tool failures. Where predictable output and low variance matter, this configuration supports tighter production control and easier process validation.

Practical application advice and support

For general turning of unalloyed and alloyed steels, select the WPP20G grade combined with appropriate cutting data for the workpiece hardness and machine rigidity. The insert’s balance of wear resistance and toughness makes it suitable for mixed-production environments where varied steel grades are processed. If clarification is required on optimal feeds, speeds or holder selection, Metav Werkzeuge’s consultants are available to advise on application-specific settings and compatible tooling combinations.

FAQ

What materials is this insert intended for?
This insert is specified for steel (ISO P) machining; the WPP20G grade is optimised for unalloyed and alloyed steels.

How does the HU3 chipbreaker improve turning operations?
The HU3 chipbreaker promotes controlled chip formation and evacuation, improving surface finish and reducing the likelihood of chip-related interruptions during turning with this Walter Tools insert.

What benefit does the 0° negative rake provide?
A 0° negative rake offers a strong cutting edge that is more resistant to chipping under heavy or interrupted cuts, enhancing edge security and tool life for demanding turning tasks.

Is the insert suitable for interrupted cuts?
Yes; the combination of a robust rake geometry and the coated carbide grade helps resist impact and wear that can occur during interrupted cutting.

How does the 1.6 mm corner radius affect surface finish?
A 1.6 mm corner radius balances edge strength with the ability to produce a consistent surface finish, making it a practical choice for general-purpose turning on steel.

Can this insert be used in high-volume production?
The Tiger·tec Gold coating and the WPP20G grade are designed to provide process stability and repeatable tool life, supporting continuous production where steel components are machined.

Does the square 90° form influence clamping and orientation?
The square 90° geometry ensures stable seating in compatible toolholders and predictable orientation, which aids repeatability and reduces set-up variance.
