LPMT150412R-D51 WKP25S rectangular milling indexable insert — 11° relief, 1.2 mm radius (Walter Tools)

The LPMT150412R-D51 WKP25S is a rectangular milling indexable insert engineered for productive face and profile milling of steel and cast iron, offering a robust balance of wear resistance and chip control.

• Tiger·tec Silver coated for longer tool life
• Optimised chipbreaker D51 for controlled chips
• Rectangular form with 1.2 mm corner radius
• Suitable for steel (P) and cast iron (K)

Consistent productivity through advanced coating and grade

The use of Tiger·tec Silver combined with the WKP25S carbide grade delivers a dependable increase in tool life and thermal resistance. The specialised coating reduces flank wear and supports higher cutting speeds, which translates into fewer indexings and longer productive cycles. For manufacturers seeking to raise line output, the coated grade helps maintain cutting edge integrity under the heat and abrasion typical of machining steels and cast irons, reducing downtime and contributing to predictable process windows.

Controlled chip flow and geometry that improves surface result

The integrated D51 chipbreaker and the insert’s rectangular insert geometry produce short, manageable chips in both ductile and brittle materials. The 11° relief provides sufficient clearance to avoid rubbing while the 1.2 mm corner radius balances edge strength with the ability to achieve good surface finishes. Controlled chip evacuation lowers the risk of re-cutting and improves reproducibility, which benefits downstream processes that depend on consistent component tolerances and surface quality.

Application focus and practical benefits for workshop use

Designed according to ISO material groups P and K, the insert is suited to unalloyed and alloyed steel as well as various cast iron grades. The stable cutting edge behaviour and the product’s tolerance class M support repeatable performance in production environments. For users with mixed batches of steel and cast iron, this insert offers a versatile solution that reduces tool inventory complexity while delivering the reliability expected in series production.

FAQ

What materials is this insert suitable for?
The LPMT150412R-D51 WKP25S is suitable for machining steel (ISO group P) and cast iron (ISO group K), combining the WKP25S grade and Tiger·tec Silver coating for reliable performance.

How does the D51 chipbreaker affect machining?
The D51 chipbreaker promotes short, controlled chips and improves chip evacuation, which helps the insert maintain consistent cutting conditions and enhances surface finish.

What advantage does the 1.2 mm corner radius provide?
A 1.2 mm corner radius increases edge strength and reduces the likelihood of chipping while still allowing good surface quality in face and profile milling operations.

Is this insert suitable for high-speed milling?
The Tiger·tec Silver coating and the WKP25S grade are designed to tolerate elevated cutting temperatures, supporting higher cutting speeds where the application and machine capabilities permit.

Which series and brand manufacture this insert?
The insert belongs to the Tiger·tec Silver series from Walter Tools and is specified under the designation LPMT150412R-D51 WKP25S.
