LPMT070304R-D51 LPMT070304R-D51 WKP25S WKP25S – milling indexable insert for Steel and Cast iron | Walter Tools (Tiger·tec Silver, 11° clearance)

The LPMT070304R-D51 WKP25S is a rectangular milling indexable insert in the Tiger·tec Silver series, designed for productive machining of steel (ISO P) and cast iron (ISO K)

• Tiger·tec Silver coating technology
• WKP25S: coated carbide grade
• 11° clearance for stable cutting
• Rectangular insert with 0.4 mm corner radius

Reliable coating and grade for consistent productivity

The combination of Tiger·tec Silver and the WKP25S grade provides a balance of wear resistance and edge stability that is particularly effective when machining Steel and Cast iron. As a coated carbide solution, this insert reduces flank wear and helps maintain dimensional accuracy across longer tool life, which translates into fewer tool changes and steadier production runs. The specification is intended to support efficient, repeatable processes where process security and predictable performance are priorities.

Geometry engineered for chip control and surface quality

The insert’s 11° clearance angle and 0.4 mm corner radius are chosen to deliver a compromise between cutting-edge robustness and ability to achieve fine surface finishes. The D51 chipbreaker promotes controlled chip formation under the thermal and mechanical conditions typical for steel and cast iron, reducing the risk of built-up edge and erratic chips. The Rectangular form factor gives stable seating in suitable cutters and allows for consistent engagement, supporting predictable tool behaviour during transverse and axial movements.

Process fit and application advantages

Specified for ISO groups P and K, this insert is suited to a wide range of milling tasks on unalloyed and alloyed steels as well as abrasive cast iron grades. With a tolerance class M, the component meets common accuracy expectations for indexable inserts and supports repeatable insert seating and clamping. The combination of grade, coating and geometry reduces downtime and can improve overall productivity by extending the interval between index changes and tool interventions.

FAQ

Which materials is this insert intended for?
The LPMT070304R-D51 WKP25S insert is intended for machining Steel (ISO P) and Cast iron (ISO K), reflecting the design focus of the Tiger·tec Silver grade.

What does the designation WKP25S indicate?
WKP25S is Walter Tools’ coated carbide grade within the Tiger·tec Silver family, selected for balanced wear resistance and edge stability suitable for steel and cast iron machining.

What chip control can be expected from the D51 chipbreaker?
The D51 chipbreaker is designed to deliver controlled, shorter chips in the typical cutting regimes encountered with steels and cast irons, improving chip evacuation and process consistency.

How does the 0.4 mm corner radius affect results?
A 0.4 mm corner radius provides improved edge strength compared with smaller radii while still supporting decent surface finish, making it a good compromise for many general milling operations.

What does tolerance class M mean for compatibility?
Tolerance class M designates common dimensional tolerances that support reliable seating in standard insert housings, ensuring repeatable positioning and predictable tool behaviour for the LPMT070304R-D51 WKP25S
