Indexable milling insert SPMW070308-A67 WKP25S — Walter Tools; Tiger·tec Silver, for Stahl & Gusseisen

SPMW070308-A67 WKP25S is an indexable milling insert engineered for high-performance finishing and semi-finishing of steel and cast materials in industrial machining.

Tiger·tec Silver coating for wear resistance
Optimised for Stahl and Gusseisen
Square 90° geometry with 0.8 mm corner radius
11° relief angle for controlled cutting forces

Greater material removal with lower tool cost

The Tiger·tec Silver coating and the WKP25S carbide grade combine to deliver improved wear resistance and consistent edge life. Designed specifically for the demands of Stahl and Gusseisen, this insert reduces flank wear and preserves cutting geometry during production runs. The result is a lower cost per component thanks to fewer indexings and extended intervals between tool changes. By using a coating technology optimised for abrasive and high-temperature conditions, the insert helps maintain a predictable process window and supports higher cutting speeds without compromising surface quality.

Stable cutting behaviour for fewer interruptions

The square 90° shape and 0.8 mm corner radius provide robust edge support and predictable chip formation. With an 11° relief angle, the insert balances cutting engagement and mechanical strength, which reduces the risk of chipping under interrupted cuts or heavy engagement. The geometry and the A67 chipbreaker are tuned to promote short, controllable chips when machining grey cast iron and to handle the long, stringy chips typical of many steels. This stability reduces unplanned downtime and simplifies tool management on multi-shift production lines.

Practical integration and consistent surface finish

Tolerance class M and the compact 07/03 geometry make the insert straightforward to integrate into standard clamping systems and cutter bodies. The design focuses on process reliability: consistent chip control leads to repeatable component quality and less rework. For job shops and production departments aiming for high throughput, the insert supports tight surface finish requirements while keeping cycle times efficient. Documentation and grade selection are geared toward quick decision-making so set-up time is minimised and throughput is maximised.

Why this insert supports long-term productivity

By combining a modern coated carbide grade with tried-and-tested geometry, the insert enables predictable tool life and reduced scrap rates. The controlled wear behaviour of WKP25S and the physical robustness of the square form offer a measurable advantage in batch production and serial machining. These technical benefits translate into operational reliability: fewer tool changes, more uptime and improved overall equipment effectiveness (OEE).
