Fräswendeschneidplatte ROHX1204M08-A57 WKP35G – milling insert for steel and cast iron by Walter Tools

ROHX1204M08-A57 WKP35G is a round milling insert engineered for consistent chip formation and robust performance in steel and cast-iron applications

• Tiger·tec Gold coating technology
• Optimised for steel and cast iron
• Round insert, 12 mm diameter
• A57 chipbreaker for controlled chips

Higher productivity through a proven coating and grade

The Tiger·tec Gold coating combined with the WKP35G grade provides a balance of wear resistance and toughness that benefits machining cycles. Designed for the ISO material groups P (steel) and K (cast iron), the insert reduces edge wear under typical heat and chip-formation conditions, which translates into fewer tool changes and steadier cycle times. The round geometry contributes to stability at the cutting edge, while tolerance class H ensures consistent seat fit and repeatable positioning in indexable holders. Such predictable behaviour supports improved process reliability and measurable productivity gains on medium- to heavy-duty milling tasks.

Better chip control and surface outcomes with the A57 chipbreaker

The integrated A57 chipbreaker promotes short, controllable chips when machining both steel and cast iron, lowering the risk of recutting and improving swarf evacuation. Controlled chip formation reduces the load on the machine and fixture, enabling higher effective machining parameters without compromising component integrity. When paired with the coated carbide substrate, the chipbreaker aids in achieving a consistent surface finish and reduces downtime for manual swarf handling, contributing directly to operational efficiency and safer shop-floor conditions.

Practical benefits for shop-floor implementation and variety of applications

The round insert format and a compact size of 12 mm with a 04 thickness accommodate a range of pocketing and peripheral milling holders commonly used in industry. The construction supports robust engagement with both unalloyed and alloyed steels as well as abrasive cast-iron grades, making it useful across production batches where material mixes occur. The specification emphasises predictable performance under varied cutting regimes, enabling process planners to standardise on an insert that delivers repeatable results without extensive parameter experimentation.

FAQ

What materials is this insert suitable for?
The ROHX1204M08-A57 WKP35G insert is specified for steel (ISO group P) and cast iron (ISO group K), using the WKP35G coated-carbide grade and Tiger·tec Gold characteristics for balanced wear resistance and toughness.

How does the A57 chipbreaker affect machining?
The A57 chipbreaker provides controlled, short chips to improve swarf management and reduce recutting; in combination with the Tiger·tec Gold coating it supports stable cutting and consistent surface finishes.

Is the insert compatible with standard round-pocket holders?
Yes, the round form and 12 mm diameter suit holders designed for round indexable inserts; tolerance class H ensures a precise fit for repeatable indexing.

What performance advantages does the WKP35G grade offer?
WKP35G is a coated-carbide grade optimised for a wide range of steel and cast-iron operations, delivering a compromise of wear resistance and edge robustness that supports longer tool life and process reliability.

Can this insert be used for finishing and roughing operations?
The insert’s chip control and coated-carbide substrate make it suitable for both stable finishing passes and productive roughing, depending on machine capability and machining parameters.
