BCMT090304R-G55 WKP25S milling insert – Parallelogram 75°, Tiger‑tec Silver (Walter Tools)

BCMT090304R-G55 WKP25S is a coated carbide milling insert designed for high‑productivity machining of steel and cast iron in CNC milling operations

• Tiger‑tec Silver coating for extended tool life
• Suitable for steel and cast iron machining
• Parallelogram 75° geometry for versatile milling
• 0.4 mm corner radius for accurate surface finish

Increased productivity through advanced coating and grade

The WKP25S grade, part of the Tiger‑tec Silver range, is a coated carbide formulation optimised for the thermal and abrasive conditions encountered when machining steel and cast iron. The advanced coating reduces flank and crater wear, which translates into longer tool life and fewer indexings. Stable chip formation and improved resistance to adhesive and abrasive wear allow higher cutting parameters without sacrificing reproducible component quality. This yields measurable productivity gains in series production and shorter overall machining cycles.

Better chip control and process reliability with G55

Equipped with the G55 chipbreaker, the insert supports controlled chip segmentation across a range of depths of cut, reducing the risk of chip entanglement and tool damage. The chipbreaker geometry is particularly effective when turning shorter, brittle chips typical of cast‑iron and when managing the continuous chips from many steels. As a result, cycle times are reduced and tool change frequency drops, which benefits throughput and floor‑level process stability in demanding production environments.

Geometry and tolerance for consistent surface quality

The parallelogram 75° form and 7° relief angle deliver a stable cutting edge orientation and favourable entry geometry for face and slot milling operations. A 0.4 mm corner radius supports improved edge strength and smoother surface finishes on the workpiece, while the insert thickness and size maintain stiffness under load. The tolerance class M ensures repeatable seating and minimal run‑out when mounted in standard toolholders, so setups remain consistent and scrap rates are reduced.

Economic operation and seamless integration into tooling systems

This indexable design allows fast repositioning of wear‑free cutting edges and lowers tooling costs per component compared with solid cutters. The BCMT090304R-G55 WKP25S insert integrates well into common CNC toolholders and is suitable for both roughing and finishing passes depending on cutting data. For production lines seeking a balance between cost efficiency and high surface quality, the insert supports stable machining strategies and predictable maintenance intervals.

FAQ

Which workpiece materials are suitable for this insert?
The BCMT090304R-G55 WKP25S insert is designed for machining steel and cast iron (ISO groups P and K), making it suitable for a broad range of unalloyed, alloyed steels and typical casting materials.

How does the G55 chipbreaker affect machining?
The G55 chipbreaker promotes short, controllable chips and reduces the risk of chip snarls; this improves process reliability for both finishing and semi‑roughing operations with steels and cast iron.

What advantages does the Tiger‑tec Silver technology provide?
Tiger‑tec Silver coating increases wear resistance and thermal stability; the result is longer tool life and the ability to run higher cutting speeds with consistent workpiece quality when using the WKP25S grade.

Is the geometry suitable for both slotting and face milling?
Yes. The parallelogram 75° form and 7° relief provide a versatile cutting orientation that suits a range of milling tasks, from slotting to profiling and face operations.

What are the key dimensions to check when ordering toolholders?
Verify the insert designation BCMT090304R‑G55, insert thickness (03), size (09) and the parallelogram seating geometry to ensure compatibility with the chosen toolholder.
