SDMT120408-F57 WPP35G milling insert (Tiger·tec Gold, 15° relief) — Walter Tools

SDMT120408-F57 WPP35G is a square 90° milling insert engineered for steel machining, featuring a Tiger·tec Gold coated carbide grade and a 0.8 mm corner radius for robust edge performance.

• Tiger·tec Gold coated for high wear resistance
• Optimised chipbreaker F57 for controlled chips
• 15° relief angle for stable cutting performance
• Square 90° form with 0.8 mm corner radius

Consistent performance for steel machining

The combination of the WPP35G grade and the Tiger·tec Gold coating delivers a balance of wear resistance and toughness tailored for P‑group materials (steel). Designed to cope with the heat and chip forms typical of steel turning and milling, this coated carbide insert ensures longer tool life under productive cutting conditions. The result is fewer tool changes, predictable wear behaviour and improved process reliability in series production.

Controlled chip formation and surface quality

The integrated F57 chipbreaker is optimised for chip control during steel machining, reducing rework and minimising downtime caused by irregular chips. By managing chip flow and fragmentation, the geometry supports stable cutting forces and contributes to consistent surface finish. For applications where repeated dimensional accuracy matters, the chipforming design reduces the risk of built-up edge and supports repeatable part quality.

Geometry that stabilises heavy cuts

The square 90° form combined with a 0.8 mm corner radius and a 15° relief angle provides a stable cutting edge that withstands intermittent loads and supports higher feed rates. The compact size 12 format lends itself to a range of milling bodies that accept SDMT-style inserts, offering rigidity in the clamped position and enabling efficient material removal with reliable edge strength.

Practical advantages in production environments

With a tolerance class M and the proven material pairing of coated carbide, the insert is suitable for general and demanding steel applications where a mix of economy and process security is required. The grade’s balance—leaning toward wear resistance while retaining enough toughness—allows for productive cutting windows and reduces scrap risk. For shops aiming to increase throughput without sacrificing component integrity, this insert provides a dependable compromise between life and performance.

FAQ

Is this insert suitable for machining standard steels?
Yes. The SDMT120408-F57 WPP35G milling insert is specifically designed for the P material group (steel) and the WPP35G grade with Tiger·tec Gold coating supports the thermal and chip‑forming characteristics of steel machining.

What does the F57 chipbreaker provide?
The F57 chipbreaker is configured to control chips during steel cutting operations; it promotes predictable chip fragmentation, supports consistent cutting forces and helps maintain surface quality during continuous production.

Can the insert be used for stainless steel or other alloys?
No specific suitability for stainless steel is stated in the data. The insert is optimised for steel (P). For stainless or high‑alloy materials, selection of a grade specified for those groups should be considered.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and allows for more stable machining under intermittent loads, improving tool life and reducing the likelihood of chipping compared with very small radii.

Which cutter bodies are compatible with this insert form?
The SDMT geometry corresponds to standard SDMT‑style milling housings. The square 90° form and size 12 designation are intended for holders designed to accept SDMT indexable inserts.
