BCMT120430L-G55 WKP35G – milling indexable insert, Tiger·tec Gold, for steel and cast iron | Walter Tools

The BCMT120430L-G55 WKP35G is a coated carbide milling insert designed for productive roughing and finishing of steel (P) and cast iron (K) in ISO 513 tool chains.

• Tiger·tec Gold coating for extended life
• Designed for steel and cast iron machining
• Parallelogram 75° geometry for stable engagement
• 3 mm corner radius and 7° clearance angle

Higher productivity through optimised grade and coating

The WKP35G grade, integrated into the Tiger·tec Gold coating system, delivers a balance of wear resistance and thermal stability that directly improves machining throughput. As a coated carbide insert developed for Steel (P) and Cast iron (K), this geometry reduces flank wear and supports a consistent cutting edge under cyclic loads. The result is longer tool life and fewer indexings per component, which lowers downtime and overall production cost while maintaining repeatable results.

Geometry that secures process stability and surface quality

The parallelogram 75° form combined with a 7° clearance angle and a 3 mm corner radius gives predictable tool engagement and favourable chip flow. This configuration reduces vibration and supports better surface finishes on mid- to heavy-section cuts. The positive geometry helps to control cutting forces on standard cutter bodies, enabling stable material removal where consistent dimensional quality is required. For operations sensitive to edge chipping, the larger corner radius offers higher edge strength and improved resistance to mechanical shock.

Practical benefits for the shop floor and tool management

Using an indexable solution with the ISO designation and series alignment simplifies tooling logistics and toolholder compatibility. The BCMT family size and the G55 chipbreaker allow easy inventory standardisation and quick changeover in modular milling heads. As a Walter Tools product, the insert contributes to process reliability and predictable wear behaviour in mixed-production environments. For applications where both Steel and Cast iron must be machined, this insert reduces the need for multiple dedicated grades and supports efficient batch sequencing.

FAQ

Which materials can be machined with this insert?
The BCMT120430L-G55 WKP35G is suitable for machining Steel (P) and Cast iron (K) as defined by ISO 513; the WKP35G coated carbide grade is optimised for the thermal and abrasive conditions typical of these groups.

What does the WKP35G grade offer compared with conventional grades?
WKP35G, within the Tiger·tec Gold family, provides improved wear resistance and thermal stability compared with uncoated or conventional coatings, enabling longer tool life and more consistent chip formation when milling steel and cast iron.

How does the geometry influence milling performance?
The parallelogram 75° shape with a 7° clearance angle and a 3 mm corner radius ensures stable cutter engagement, promotes favourable chip flow with the G55 chipbreaker and improves surface finish while reducing the risk of edge chipping under interrupted cuts.

Is the insert compatible with standard BCMT toolholders?
Yes, the BCMT120430L-G55 WKP35G follows standard BCMT designation and is intended for use in compatible indexable milling toolholders that accept the BCMT form and size.
