BCMT120408R-K55 WKP35S — Milling indexable insert, Tiger·tec Silver (Walter Tools)

The BCMT120408R-K55 WKP35S is a milling indexable insert developed for efficient machining of steel and cast iron, featuring a Parallelogram 75° geometry, a 7° relief and a 0.8 mm corner radius for stable cutting performance

• Tiger·tec Silver coating, WKP35S grade
• Optimised K55 chipformer for controlled chips
• Parallelogram 75° shape with 0.8 mm corner
• Suitable for steel (P) and cast iron (K)

High-performance cutting for mixed production runs

The Tiger·tec Silver coating combined with the WKP35S cutting grade delivers optimised wear resistance and consistent edge behaviour across a wide range of steels and cast irons. This balance of hardness and toughness reduces flank and crater wear under typical milling temperatures, which translates into longer tool life and fewer index changes. For production environments that require repeatable results, the coated substrate minimises the risk of unexpected tool failure and supports stable cycle times.

Geometry designed for repeatable dimensional accuracy

The insert’s Parallelogram 75° form and 0.8 mm corner radius ensure predictable engagement and improved surface finish during shoulder and face milling. The 7° relief angle helps to reduce rubbing at the cutting edge, lowering cutting forces and vibration. As a result, the component tolerances remain consistent across batches, and finishing passes can be reduced. The shape also supports positive cutting conditions that favour efficient chip evacuation.

Controlled chip formation for safer machining

Equipped with the K55 chipformer, the insert actively conditions chips to break and evacuate cleanly in both steel and cast iron applications. Controlled chip flow reduces re-cutting, heat concentration and the potential for tool interference, improving both operator safety and process uptime. For mixed-material workshops, this reliable chip behaviour simplifies tooling strategies and reduces the need for frequent process adjustments.

Practical use and handling for workshop efficiency

The insert is supplied in the defined designation and geometry for straightforward tool selection and inventory management. The clear series and grade marking support fast allocation to holders and machines, while the indexable insert format allows multiple re-uses of the cutting edges before replacement. For operators new to coated grades, it is recommended to start with conservative cutting data and increase speeds gradually while monitoring tool wear to find the most economical balance for the specific machine and workpiece.

FAQ

What materials is this insert suitable for?
The BCMT120408R-K55 WKP35S insert is designed for machining steel (P) and cast iron (K), utilising the Tiger·tec Silver coating and WKP35S grade to handle typical thermal and abrasive conditions.

How does the K55 chipformer affect machining?
The K55 chipformer promotes predictable chip breakage and evacuation; this reduces re-cutting and thermal concentration when using the insert in milling operations on steel and cast iron.

What benefit does the Parallelogram 75° shape provide?
The Parallelogram 75° geometry gives a positive cutting approach that improves surface finish and allows stable engagement during shoulder and face milling, aiding dimensional consistency.

Is the insert compatible with standard tool holders?
The insert follows the BCMT designation and is intended for compatible indexable milling holders; correct seat and clamping must be used to ensure stable performance.

What maintenance practice extends tool life?
Monitoring wear and adjusting cutting parameters progressively when using the WKP35S grade helps extend edge life; the coated substrate of the insert reduces wear but benefits from process optimisation.
