CNMU120608-D57T WKP35S indexable milling insert for steel and cast iron — Walter Tools, Tiger·tec Silver, 0° negative rake

The CNMU120608-D57T WKP35S is an indexable milling insert engineered for productive face and shoulder milling of steels and cast irons, offering a robust geometry and a coated carbide grade for high process reliability

• Tiger·tec Silver coated grade WKP35S
• Optimised chip control with D57T chipbreaker
• Rhombic 80° geometry, 0.8 mm corner radius
• Designed for steel (P) and cast iron (K)

Improved cutting performance through advanced coating

The use of Tiger·tec Silver coating combined with a WKP35S substrate provides reliable wear resistance and thermal stability during continuous milling cycles. This coated carbide formulation is tailored to handle the heat and abrasion commonly encountered when machining steels and cast irons, meaning longer tool life and fewer insert changes. For production environments seeking to increase throughput, the coating supports higher cutting parameters without sacrificing edge integrity, resulting in more consistent component tolerances and reduced process interruptions.

Geometry and chip control for stable machining

The rhombic 80° geometry and 0.8 mm corner radius deliver a good balance between edge strength and cutting engagement, suitable for both shoulder and peripheral milling tasks. The 0° negative rake increases cutting edge robustness for interrupted cuts and tougher workpiece conditions, while the D57T chipbreaker is designed to promote short, controlled chips on both steel and cast iron. These characteristics reduce the risk of chip-related surface damage and improve machine uptime, so fewer interventions are needed during series production.

Typical applications and practical handling notes

Designed primarily for the ISO P and K workpiece groups, this insert is well suited to general milling operations where a combination of process security and cost efficiency is required. The insert’s tolerance class M and thickness code 06 ensure repeatable seating in standard cutter bodies; check holder compatibility for CNMU-style indexable geometry. When setting cutting data, prioritise stable feeds and moderate speeds adapted to the workpiece grade to exploit the grade’s abrasion resistance and maintain surface quality. For mixed-production environments, the insert’s adaptability to both steel and cast iron helps simplify tooling inventories.

FAQ

What materials is this insert suitable for?
The CNMU120608-D57T WKP35S is designed for machining steel (P) and cast iron (K), exploiting the WKP35S grade’s abrasion resistance and thermal stability.

How does the D57T chipbreaker affect machining?
The D57T chipbreaker promotes short, controllable chips and improves chip evacuation on both steel and cast iron, reducing the likelihood of surface damage and downtime.

Is the insert suitable for interrupted cuts?
Yes; the 0° negative rake and a 0.8 mm corner radius increase edge robustness, making the insert well suited to interrupted and heavy engagement milling conditions.

Which holder type is required for this insert geometry?
This is a CNMU-style rhombic 80° indexable milling insert; ensure the cutter body accepts CNMU inserts and that seating tolerances match the tolerance class M.

What benefits does Tiger·tec Silver offer in production?
Tiger·tec Silver coating provides improved wear resistance and thermal stability, enabling higher cutting parameters and consistent edge life for production milling tasks.
