BCMT120412R-G55 WKP35G milling insert (Parallelogram 75°, 1.2 mm corner radius) — Walter Tools

The BCMT120412R-G55 WKP35G is a Tiger·tec Gold coated milling insert designed for productive machining of steel and cast iron with reliable chip control and edge stability

• Tiger·tec Gold coating for durable edge
• G55 chipbreaker for stable chip control
• Parallelogram 75° geometry for versatile milling
• 1.2 mm corner radius for improved strength

Maximise uptime with wear-resistant Tiger·tec Gold grade

The coated carbide WKP35G grade, part of the Tiger·tec Gold series, offers a balanced combination of wear resistance and thermal stability for high-volume milling. The multilayer coating reduces abrasive and adhesive wear on the cutting edge, which translates into longer tool life and fewer indexings. For manufacturers working with alloyed and unalloyed steel, this means fewer tool changes and a steadier production flow, improving overall equipment effectiveness and process economy.

Consistent chip control and improved surface quality

The G55 chipbreaker is engineered to produce predictable, controlled chips when machining both steel and cast iron. Controlled chip formation reduces the risk of built-up edge and prevents chip entanglement, supporting safer high-feed and interrupted cuts. As a consequence, surface finish remains more consistent and downstream finishing operations are often reduced. The insert’s geometry contributes directly to surface integrity and repeatable results.

Stable geometry for secure clamping and versatile feeds

The parallelogram 75° shape and 1.2 mm corner radius deliver mechanical strength and flexible cutting engagement. The form factor supports a range of axial and radial depths of cut while maintaining edge support under moderate loads. A modest relief angle of 7° helps to balance cutting forces and reduce friction at the cutting zone. These geometric choices make the insert suitable for a variety of milling strategies, from light finishing to more aggressive semi-finishing passes.

Clear material suitability and efficient process selection

Classified for ISO groups P and K, the insert is intended primarily for steel and cast iron applications. The coated carbide grade is optimised for the thermal and mechanical demands of these materials: it copes with the heat and typical chip forms of steel and withstands the abrasive nature of many cast irons. When combined with an appropriate feed and speed strategy, the result is economical machining with predictable tool life and reproducible component quality.

FAQ

What materials is this insert suitable for?
The BCMT120412R-G55 WKP35G milling insert is designed for ISO groups P and K, making it suitable for machining steel and cast iron with optimised wear resistance.

How does the Tiger·tec Gold coating benefit machining?
Tiger·tec Gold coating on the WKP35G grade improves resistance to abrasive and adhesive wear, which helps maintain cutting-edge integrity and extends usable tool life in continuous milling operations.

What is the purpose of the G55 chipbreaker?
The G55 chipbreaker delivers controlled chip formation for safer chip evacuation and reduced built-up edge, supporting consistent surface finish and more reliable high-feed or interrupted cuts.

Can the parallelogram 75° geometry be used for different milling strategies?
Yes, the parallelogram 75° shape provides flexibility for a range of axial and radial engagements, enabling semi-finishing and finishing passes while maintaining a robust cutting edge.

What machining advantages does the 1.2 mm corner radius offer?
A 1.2 mm corner radius increases edge strength and distributes cutting forces more evenly, which is beneficial for moderately heavy cuts and improves edge life.
