LCMX050203-E57 WKP25S – drilling/boring indexable insert, Tiger‑tec Silver, Walter Tools

The LCMX050203-E57 WKP25S is a rectangular indexable insert developed for drilling and boring operations in steel and cast iron, combining a 7° relief and a 0.3 mm corner radius for reliable chip control and repeatable edge stability

• Tiger‑tec Silver coating for extended tool life
• Suitable for steel (P) and cast iron (K)
• Chipbreaker E57 for consistent chip control
• Rectangular form with 0.3 mm corner radius

High‑productivity performance for holemaking

The coated cutting grade WKP25S within the Tiger‑tec Silver family is engineered for productive machining of ISO groups P and K. The combination of a wear‑resistant coating and a geometry optimised for interrupted or continuous cuts yields longer intervals between index changes and reduces unplanned downtime. By balancing thermal resistance and edge stability, the insert supports higher cutting speeds and steady material removal rates, making it suitable for series production where process reliability is crucial. The design therefore translates directly into measurable productivity gains on the shop floor.

Controlled chip formation and improved surface quality

Chip management is central to efficient holemaking; the integrated chipbreaker E57 shapes chips consistently, reducing entanglement and easing evacuation in deep or confined holes. The modest 0.3 mm corner radius combined with a 7° clearance angle helps maintain a robust cutting edge while limiting radial cutting forces, which in turn promotes better surface finish and hole accuracy. For operations where repeatability matters, this geometry reduces vibration and supports stable tool‑workpiece interaction, yielding predictable results across batches.

Simple integration and process security

The rectangular format and standard designation ensure straightforward insertion into compatible toolholders and drills. The insert’s coding (LCMX050203‑E57) follows common conventions for quick identification during tool setup and inventory management. Material compatibility—specified for steel (P) and cast iron (K)—provides clear guidance when selecting the grade for mixed production runs. With tolerance class M, the component meets regular interchangeability expectations, simplifying the qualification of the cutting edge in existing workflows and minimising setup time.

Application recommendations and selection guidance

For best results, match the insert geometry and chipbreaker to the chosen toolholder and the specific drilling or boring cycle. The WKP25S grade is particularly effective where a balance of wear resistance and toughness is required; it performs well in unalloyed and alloyed steels as well as in various cast iron grades. Operators seeking extended life under higher thermal loads will benefit from the Tiger‑tec Silver coating’s resistance to abrasive and thermal wear. When in doubt about holder compatibility or cutting data, consult process engineers to adapt feeds and speeds for the intended machine and clamping conditions.

FAQ

What materials is this insert suitable for?
The LCMX050203‑E57 WKP25S insert from Walter Tools is designed for ISO groups P and K, meaning it is suitable for machining steel and cast iron workpieces.

How does the Tiger‑tec Silver coating benefit performance?
The Tiger‑tec Silver coating on the LCMX050203‑E57 WKP25S enhances thermal and abrasive wear resistance, which extends tool life and maintains edge stability during productive holemaking.

What is the purpose of the E57 chipbreaker?
The chipbreaker E57 on this indexable insert controls chip form and evacuation, promoting consistent chips and reducing the risk of jamming during drilling and boring operations.

How should the corner radius and clearance angle influence cutting data?
The 0.3 mm corner radius and 7° clearance angle support a robust cutting edge with controlled forces; feeds and speeds should be adjusted to balance finish and tool life according to workpiece material and holder rigidity.

Is this insert compatible with standard rectangular holders?
The rectangular form and standard designation LCMX050203‑E57 indicate compatibility with commonly used rectangular toolholders designed for this insert geometry; verify holder specification before ordering.
