LDMT14T308R-D57 WKP25S rectangular milling insert, Tiger·tec Silver – Walter Tools

The LDMT14T308R-D57 WKP25S is a rectangular milling insert engineered for productive machining of steel and cast iron, combining a wear-resistant coating with a chipbreaker designed for secure material removal.

• Tiger·tec Silver coated carbide grade WKP25S
• Optimised chip control D57 chipbreaker
• 15° relief angle for secure cutting
• Rectangular form with 0.8 mm corner radius

Consistent cutting performance for steel and cast iron

The combination of the Tiger·tec Silver coating and the WKP25S carbide grade is optimised for typical heat loads and abrasion encountered when machining steel and cast iron. The coating enhances wear resistance and reduces flank wear, which increases process stability and extends tool life. For production environments this means fewer tool changes and more predictable component quality. The designation for workpiece groups P (steel) and K (cast iron) indicates the insert's intended material range and helps selecting the correct geometry for catalogue- or job-specific applications.

Geometry that improves strength and surface quality

A rectangular plate with a 0.8 mm corner radius and a 15° relief angle balances edge robustness with clearance during cutting. The modest corner radius increases edge strength for interrupted cuts and supports longer life without compromising finishing capability. The D57 chipbreaker actively shapes and breaks chips, reducing chatter and evacuation issues, which in turn lowers the risk of rework. With a plate thickness of T3 and tolerance class M, the insert offers reliable seating accuracy and repeatable clamping behaviour on toolholders adapted to this geometry.

Productivity, handling and process reliability

Designed as an indexable solution, the insert reduces setup time and allows rapid rotation to fresh cutting edges, supporting continuous production. The engineered grade and chip control cater to both roughing and semi-finishing operations depending on cutter geometry, enabling efficient material removal rates and consistent component tolerances. Walter Tools' series is known for stable edge life and process security; when paired with a suitable cutter body and cutting data, the insert contributes to lower unit costs and predictable cycle times. If clarification on suitable cutter bodies or cutting parameters is required, technical advice is available from Metav Werkzeuge.

FAQ

Which materials are best machined with this insert?
The LDMT14T308R-D57 WKP25S insert is formulated for steel (P) and cast iron (K); the Tiger·tec Silver coating and WKP25S grade optimise wear behaviour for these groups.

What does the D57 chipbreaker do in practice?
The D57 chipbreaker breaks and guides chips to improve evacuation and reduce surface damage; this leads to more stable cutting and fewer interruptions during long cycles with the LDMT14T308R-D57 WKP25S insert.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength and improves resistance to chipping in interrupted cuts while still allowing good surface finish in semi-finishing applications with the same insert.

Is the insert suitable for finishing passes?
Depending on cutter geometry and cutting data, the LDMT14T308R-D57 WKP25S can be used for semi-finishing and certain finishing tasks; the grade and chip control support consistent surface quality under appropriate feeds and speeds.

What does tolerance class M mean for mounting?
Tolerance class M indicates a medium dimensional tolerance that ensures reliable seating and repeatable clamping accuracy when paired with matching toolholders, supporting consistent tool performance.
