LDMT08T204R-F57 WKP35S milling insert — Tiger·tec Silver coated carbide for steel and cast iron, Walter Tools

LDMT08T204R-F57 WKP35S is a rectangular milling insert engineered for productive face and shoulder milling of steel and cast iron components, combining a robust coated-carbide grade with a chipbreaker designed for controlled swarf evacuation

• Tiger·tec Silver coated carbide WKP35S
• Optimised for steel and cast iron machining
• 15° clearance angle for stable cutting
• 0.4 mm corner radius, rectangular format

Increase throughput on P and K materials

The WKP35S grade, applied in the Tiger·tec Silver series, is a coated carbide solution optimised for ISO groups P (steel) and K (cast iron). Its composition and coating technology enable higher cutting parameters while maintaining wear resistance, so material removal rates can be raised without sacrificing component quality. The F57 chipbreaker contributes to predictable chip formation, lowering the risk of workpiece damage and reducing unplanned downtime. For production contexts where repeatability and cycle-time reduction matter, this geometry-grade combination supports a more efficient machining process.

Stable edge life and reliable surface results

A 0.4 mm corner radius and 15° clearance angle provide a balance between strength and surface finish: the radius reduces edge chipping on interrupted cuts, while the clearance angle prevents rubbing at the flank, improving tool life and consistency. The insert’s rectangular format adds rigidity in the clamping pocket, which is particularly beneficial during heavy shoulder cuts. Tolerance class M and the defined plate thickness ensure interchangeability and repeatable performance across toolholder changes, helping to keep setup variance and scrap rates low.

Geometry and handling explained for straightforward integration

Designation LDMT08T204R-F57 gives immediate information for tooling planners: plate size "08", thickness T2, chipbreaker F57 and the rectangular outline. The practical result is straightforward selection for compatible cutter bodies and minimal adaptation in existing tool rigs. The coating reduces friction and heat at the cutting edge; for operators unfamiliar with coated-carbide grades, this means fewer edge failures under comparable cutting speeds and improved resistance to abrasive wear when machining cast materials.

What this delivers to the production line

In short, the combination of the Tiger·tec Silver coating and the WKP35S grade delivers process stability, lower variance in component finish, and extended intervals between index changes. The insert is well suited to mixed batches where both steel and cast iron are machined, offering a single-grade option to simplify inventory. Walter Tools’ engineering background supports reliable edge preparation and coating quality, contributing to predictable performance in serial production environments.

FAQ

Which materials is the insert suitable for? The LDMT08T204R-F57 WKP35S is specified for ISO material groups P (steel) and K (cast iron), making it suitable for a broad range of general structural steels and grey/ductile cast irons.

What does the WKP35S grade offer? WKP35S is a Walter coated-carbide grade within the Tiger·tec Silver series; it emphasises wear resistance and stable chip formation for productive machining of steel and cast iron.

What are the key geometry values to consider? Key values are a 15° clearance angle, 0.4 mm corner radius, rectangular plate shape and a plate size of 08 with thickness T2, which together define cutting behaviour and clamping stability.

How does the F57 chipbreaker affect cutting? The F57 chipbreaker is designed to control chip shape and evacuation during medium to heavy machining; it supports continuous and interrupted cuts typical in steel and cast-iron operations.

Is this insert recommended for stainless steel or high-temperature alloys? No specific approval for stainless steel or exotic alloys is provided in the data; the LDMT08T204R-F57 WKP35S is optimised for steel and cast iron and may not deliver the same performance on austenitic stainless steels or superalloys without parameter adjustments.
