BCMT120408R-K55 WKP35G milling insert — Tiger·tec Gold grade for steel and cast iron machining, K55 chipbreaker — Walter Tools

The BCMT120408R-K55 WKP35G is a precision milling insert designed for productive machining of steel and cast iron, combining a coated carbide grade with a controlled-chip geometry for versatile milling tasks.

*Tiger·tec Gold coating for high process security
*WKP35G grade optimised for steel and cast iron
*K55 chipbreaker for controlled chip formation
*Parallelogram 75° form with 7° clearance

Productivity through a robust graded coating

The coated carbide grade WKP35G belongs to the Tiger·tec Gold series and is engineered to improve process security and tool life in mixed production environments. The coating reduces abrasive wear and stabilises the cutting edge, which results in fewer tool changes and higher net productivity. As a consequence, workshops benefit from more predictable machining cycles and improved overall equipment effectiveness when using this insert.

Reliable chip control and surface outcome

The K55 chipbreaker is designed to produce short, controlled chips in both steel and cast iron, supporting safer swarf handling and uninterrupted machining. The combination of chipbreaker geometry and the insert’s clearance angle of 7° helps maintain a stable cutting temperature and consistent surface finish. The 0.8 mm corner radius supports moderate strength at the cutting edge while enabling acceptable finish quality on common engineering materials.

Geometry that supports flexibility and repeatability

The insert’s parallelogram shape with a 75° cutting edge offers a versatile engagement angle for a wide range of milling strategies. With a nominal size of 12 and a plate thickness of 04, this indexable plate is compatible with many standard milling cutter bodies and seats within tolerance class M for repeatable positioning. These geometric attributes contribute to predictable tool behaviour and reduced setup times across batch sizes.

Application advantages and practical use

As a member of the Tiger·tec Gold family by Walter Tools, the insert is particularly suitable for production and job-shop environments that require durable performance on steel and cast iron components. The coated grade and chipbreaker balance wear resistance and chip evacuation, lowering the risk of built-up edge and enabling consistent cycle times. For specific cutting data and optimal feeds, technical consultation is recommended to match cutter body, clamping, and machine rigidity to the intended operation.

FAQ

Is this insert suitable for stainless steel applications?
The insert is specified for steel and cast iron (P/K); stainless steel suitability is not listed for the BCMT120408R-K55 WKP35G, so material-specific testing or consultation is recommended.

What does the WKP35G designation mean?
WKP35G denotes a Walter Tools coated carbide grade within the Tiger·tec Gold family, developed for high process reliability and broad workpiece coverage, particularly for steel and cast iron applications.

How does the K55 chipbreaker influence machining?
The K55 chipbreaker promotes short, controlled chips and stable swarf flow during milling of steel and cast iron, which improves safety and reduces the likelihood of chip-related interruptions.

Which geometric features are most relevant for setup?
Key specs are the 7° relief angle, 0.8 mm corner radius and the parallelogram 75° form; these determine cutter engagement, strength and achievable surface quality for the BCMT120408R-K55 WKP35G.
