• Square 90° insert form with 20° clearance
• Tolerance class H with reliable chip control

Longer tool life and consistent productivity with Tiger·tec Gold

The Tiger·tec Gold technology and the WPP35G grade combine a coated carbide substrate with a modern coating system engineered for steel machining. This results in improved resistance to flank wear and stable cutting-edge behaviour under thermal load. The coating and substrate pairing target the typical heat generation and chip formation seen when machining unalloyed and alloyed steels, delivering extended edge life and fewer insert changes. For production environments this translates into steadier cycle times and reduced tooling interventions, supporting higher overall equipment effectiveness.

Geometric stability and process security for demanding milling tasks

A square 90° insert form with a 20° clearance provides a robust cutting geometry that supports both face and shoulder milling operations. The insert size code 12 together with thickness code 04 yields a compact yet stable cutting body suitable for medium to heavy engagement. The specified tolerance class H ensures repeatable seating in the toolholder and predictable runout behaviour, which benefits surface finish and dimensional consistency. Where chip control is critical, the combination of the insert form and the WPP35G grade promotes stable chip breaking and manageable swarf evacuation.

Practical selection and application guidance for production planners

For machining strategies focused on steels (ISO P), the grade offers a balanced compromise between wear resistance and toughness, categorised as suitable across several cutting conditions: wear-resistant for higher speeds and universal for a broad range of operations. The insert’s coated carbide construction supports elevated cutting parameters while maintaining process security and consistent surface quality. When integrating the insert into a production line, pairing it with a matching Walter Tools toolholder and optimised cutting data will help to exploit the productivity and longevity benefits of the Tiger·tec Gold range.

FAQ

What materials is this insert recommended for?
The SEHT1204AFN WPP35G insert is optimised for steel (ISO P group); the WPP35G grade is tailored to handle the heat and chip formation typical of unalloyed and alloyed steels.

How does the Tiger·tec Gold series benefit milling operations?
Tiger·tec Gold provides a modern coating-substrate combination that increases wear resistance and edge stability, helping the SEHT1204AFN WPP35G maintain consistent performance and extend tool life in production use.

What advantages does the square 90° geometry provide?
The square 90° form offers a robust cutting edge suited for shoulder and face milling, improving stability under radial load and supporting reliable surface finish results.

Is the insert suitable for high-speed machining?
The coated carbide construction of the WPP35G grade supports elevated cutting speeds while maintaining edge life; actual parameters depend on workpiece material, depth of cut and toolholder rigidity.

What does tolerance class H mean for insertion accuracy?
Tolerance class H indicates tight manufacturing tolerances for the insert, which ensures repeatable seating in the toolholder and predictable runout, contributing to dimensional consistency and process reliability.
