LCMX050203-B57 WKP25S rectangular drilling/boring indexable insert for steel & cast iron — Walter Tools

LCMX050203-B57 WKP25S is a rectangular indexable insert engineered for drilling and boring operations in steel and cast iron, combining a coated carbide grade and a dedicated chipbreaker for stable and productive machining.

• Tiger‑tec Silver coating for long tool life
• Suited for steel and cast iron machining
• 7° clearance angle for stable cutting
• 0.3 mm corner radius for consistent surface finish

Boosted productivity through optimised grade and coating

The combination of the WKP25S grade with the Tiger‑tec Silver coating translates into measurable productivity gains in serial operations. The coated carbide substrate resists abrasive wear and thermal loads typical of steel and cast iron machining, which reduces changeover frequency and minimises unplanned downtime. As a result, cycle times become more predictable and tool-related variability is reduced, supporting tighter process control and higher output per shift.

Precise chip control and cutting stability

Built around a defined chipbreaker B57 and a rectangular geometry, the insert ensures predictable chip formation and evacuation when machining both steel and cast iron. The 7° clearance angle promotes steady engagement with the workpiece, decreasing chatter and improving dimensional stability. This leads to more consistent toolpaths and fewer scrap parts, particularly when the component geometry demands repeatable hole or bore quality.

Durable edge geometry for improved surface quality

A 0.3 mm corner radius delivers a balance between cutting strength and surface finish; the robust edge resists micro‑chipping while smoothing the transition on the bore wall. The coated cutting surface maintains its cutting line longer under thermal stress, which means fewer interruptions for dressing or insert changes. For manufacturers prioritising component appearance or close tolerances, the geometry and coating together contribute to reliable finishing performance.

Practical selection and application guidance

The rectangular indexable insert form and its compatibility with the P / K material groups (steel and cast iron) make it appropriate for drilling and boring operations where both wear resistance and chip handling are required. Selection should consider spindle speed, feed and the machine’s rigidity; when combined with appropriate holder choice and coolant strategy, the insert supports steady, high‑quality results. For application matching, specify the plate size and thickness to ensure holder compatibility.

FAQ

Which workpiece materials are suitable with this insert?
The LCMX050203-B57 WKP25S insert is suitable for steel and cast iron machining, corresponding to the P and K ISO groups, which the Tiger‑tec Silver grade is optimised to handle.

What does the WKP25S grade signify?
WKP25S is Walter Tools’ coated carbide grade within the Tiger‑tec Silver family; it offers balanced wear resistance and thermal stability for demanding drilling and boring operations.

How does the chipbreaker B57 affect performance?
The chipbreaker B57 shapes and breaks chips to improve evacuation and reduce the risk of recutting, contributing to more stable cutting conditions and consistent bore quality with this indexable insert.

Is the corner radius suitable for finishing operations?
Yes, the 0.3 mm corner radius provides a compromise between edge strength and surface finish, supporting improved durability without sacrificing the ability to achieve fine finishes.

Which cutting conditions benefit most from this insert geometry?
Applications with medium to high material removal rates in steel and cast iron, where chip control and edge stability are critical, benefit most from the rectangular insert geometry and its 7° clearance angle.
