BCMT120408R-G55 WKK25G — Indexable milling insert (Parallelogram 75°, 7° clearance) by Walter Tools

The BCMT120408R-G55 WKK25G is a parallelogram indexable milling insert engineered for productive machining of cast iron components in industrial milling applications.

• Tiger·tec Gold coated insert
• Optimised for cast iron (ISO K)
• Parallelogram 75° geometry
• 0.8 mm corner radius, 7° clearance

Stable machining through dedicated coating and grade

The combination of the Tiger·tec Gold coating and the WKK25G coated-carbide grade provides high resistance to abrasive wear, which is typical in cast iron machining. The coated surface reduces flank wear and extends the period between index changes, resulting in improved process uptime and lower tooling costs per component. The designation for cast iron (ISO K) signals that the cutting edge geometry and coating are tuned to manage short, brittle chips and abrasive particles without compromising edge life.

Geometry that supports reliable chip formation and surface quality

The parallelogram 75° insert form, together with a 7° clearance angle, produces a cutting action that balances radial and axial forces for stable milling passes. The 0.8 mm corner radius enables a robust cutting edge for heavier engagement while maintaining acceptable surface finish on casting materials. The built-in G55 chipbreaker helps to fragment and evacuate chips effectively, reducing re-cutting and thermal impact on the cutting edge — a pragmatic advantage in series production and interrupted cuts.

Practical benefits for production planning and process security

As an indexable insert with standard BCMT seating and a nominal plate size of 12 mm and thickness 4 mm, the component integrates easily into existing toolholders, facilitating quick index changes and predictable tool life. The insert supports consistent cycle times and repeatable results in cast iron operations, contributing to traceable productivity gains. Walter Tools’ engineering focus on process reliability complements the grade characteristics, making this insert suitable where reproducible performance and stable chip control are priorities.
