SEKR1203AFTN WPP35G indexable milling insert, square 90°, 20° relief – Walter Tools

The SEKR1203AFTN WPP35G is a square 90° indexable milling insert with a Tiger·tec Gold coating, engineered for productive machining of steel under typical cutting temperatures and chip formation conditions.

• Tiger·tec Gold coating for extended tool life
• Square 90° form for robust shoulder milling
• Optimised for steel (ISO P) machining
• 20° relief angle for stable cutting performance

Longer tool life through advanced coating technology

The Tiger·tec Gold coating, represented by the WPP35G grade, combines a wear-resistant, coated carbide substrate that is tailored to the demands of steel machining. This coating reduces flank and crater wear, which in turn extends component life and lowers tool-change frequency. For production environments where uptime and consistent results matter, the coated grade offers improved process reliability and predictable tool performance under elevated temperatures.

Robust geometry for repeatable shoulder milling

A square 90° plate design with a 20° relief angle provides a stable cutting edge and even load distribution across the insert corner. The SEKR-style geometry, with a standard thickness of 03, ensures repeatable results when performing shoulder cuts and face milling operations. This geometry supports controlled chip formation and dimensional consistency, which is particularly valuable for batch production where tolerance retention is critical.

Designed specifically for steel — efficiency and economy

The insert is developed for group P materials according to ISO 513, making it well suited to unalloyed and alloyed steel. The grade structure balances wear resistance and toughness (noted across the range as wear-resistant and universal to tougher applications), delivering an economical alternative for medium to heavy-duty milling. The result is a favourable cost-per-part ratio: fewer tool changes and consistent surface quality translate into lower overall machining costs.

Seamless integration with common toolholders and workflows

The insert’s ISO designation and form allow straightforward integration into standard milling cutters that accept SEKR plates, enabling quick indexation and minimal setup time. With a tolerance class K, users obtain precise seating and repeatability. The plate’s execution marked as R denotes the specific lead or orientation, which aids in correct tool assembly and predictable cutting direction during tool changes and reconditioning cycles.

FAQ

What materials is this insert suitable for?
The SEKR1203AFTN WPP35G insert is formulated for machining steel (ISO P); the WPP35G grade is optimised for typical steel chip formation and thermal behaviour.

How does the Tiger·tec Gold coating benefit production?
Tiger·tec Gold on the WPP35G grade increases wear resistance and supports longer tool life, which reduces downtime and improves the consistency of results over longer production runs.

Can the insert be used in standard SEKR toolholders?
Yes, the SEKR1203AFTN geometry complies with common SEKR-style toolholders and offers a tolerance class K for precise seating and repeatable indexing.
