BCMT120404R-G55 WPP35G – Milling indexable insert, Tiger·tec Gold for Stahl | Walter Tools

The BCMT120404R-G55 WPP35G is a precision milling insert designed for productive steel machining, combining a Tiger·tec Gold coating with an optimised G55 chipformer for consistent performance.

• Tiger·tec Gold coating for high wear resistance
• Optimised G55 chipbreaker for stable chip control
• Parallelogram 75° form for secure clamping
• 7° clearance and 0.4 mm corner radius precision

High productivity through enhanced coating technology

The insert’s Tiger·tec Gold coating provides a pronounced improvement in wear resistance and thermal stability compared with uncoated grades, enabling higher cutting speeds and longer tool life. As a coated carbide grade, the WPP35G composition is balanced for both toughness and abrasion resistance, which translates into fewer index changes and reduced consumable costs. For manufacturers aiming to increase throughput, the combination of coating and substrate means repeatable performance in a range of Stahl machining tasks.

Stable chip control and surface integrity for fewer reworks

The dedicated G55 chipbreaker is tuned to produce short, controllable chips when machining Stahl, reducing the risk of chip entanglement and improving process reliability. The insert geometry—a parallelogram 75° form with a 0.4 mm corner radius—supports consistent edge engagement and contributes to a superior surface finish in semi‑finishing and finishing passes. Better chip evacuation and a predictable cutting edge reduce secondary operations and increase first‑pass yields.

Robust geometry and tolerance for secure production runs

With a 7° clearance angle and tolerance class M, this indexable insert is manufactured to deliver repeatable seating and stable cutting conditions in standard toolholders. The specified dimensions and form ensure precise clamping and alignment, which minimises vibration and extends the life of both the insert and the holder. These geometrical benefits lead to lower machine downtime and steady process capability across batch and serial production.

Versatile application and process efficiency

Engineered for Stahl group materials, the WPP35G grade is suitable across a wide hardness and alloy spectrum commonly encountered in industrial production. The insert’s balanced toughness and wear resistance make it a good choice for mixed production environments where a single grade must handle varied components. For bespoke process windows or to optimise cutting data for specific steels, consultation is recommended to maximise productivity while maintaining component quality.

FAQ

What materials is this insert designed for?
The WPP35G grade is specified for the machining of Stahl (group P), covering unalloyed and alloyed steels with a focus on reliable chip control and edge life.

What advantages does the Tiger·tec Gold coating provide?
The Tiger·tec Gold coating on the BCMT120404R-G55 WPP35G increases wear resistance and thermal stability, supporting higher cutting speeds and longer service life compared with conventional uncoated carbides.

Why is the G55 chipbreaker important for production?
The G55 chipbreaker provides optimised chip formation for Stahl, producing short, manageable chips and improving process stability which reduces the likelihood of machine interruptions.

Is the insert suitable for finishing operations?
Yes, the combination of the 0.4 mm corner radius and precise geometry supports good surface quality in finishing passes while retaining robustness for semi‑finishing applications.

What are the key geometric specifications to check before setup?
Confirm the parallelogram 75° form, 7° clearance angle and the insert dimensions (size 12, thickness 04) to ensure correct seating and clamping in the toolholder.
