P4840C-7R-E67 WXP40 drilling/boring indexable insert — Walter Tools

The P4840C-7R-E67 WXP40 is an indexable insert designed for productive drilling and boring operations, featuring an uncoated carbide grade and a 7R‑E67 chipbreaker for enhanced chip control.

• Uncoated carbide grade WXP40
• 7R‑E67 chipbreaker for stable chips
• Suited to productive drilling and boring

Stable chip control for uninterrupted production

The combination of the 7R‑E67 chipbreaker and the WXP40 uncoated carbide grade is engineered to deliver consistent chip formation and reduced tendency for long, stringy chips. The chipbreaker geometry directs and fractures chips during drilling and boring cycles, which helps to avoid rework and tool stoppages. For production environments where cycle stability and predictable tool behaviour are priorities, this configuration contributes to fewer interventions and improved overall equipment effectiveness. Note that workpiece suitability should be verified against the product matrix to ensure optimum cutting parameters.

Geometry and indexing for efficient tool handling

The insert geometry is tailored to secure reliable seating and repeatable cutting angles in indexable toolholders, shortening the time needed for tool changes. As an indexable insert, it allows machining to continue with minimal interruption by rotating to a fresh cutting edge rather than replacing an entire tool. This design supports straightforward inventory management and lower per‑edge costs. The nominal designation encodes the geometry and chipbreaker — use the code to select matching holders and clamping systems for precise alignment and repeatable results.

Practical selection and integration guidance

Selection of the correct insert grade and chipbreaker is a technical decision that depends on material, machine capability and process strategy. The WXP40 grade is uncoated carbide and is provided as part of Walter’s open series; therefore, the workpiece material compatibility must be checked in the detailed product matrix. For shops seeking increased process reliability, pairing the insert with appropriate cutting parameters and rigid tooling significantly reduces variation in surface finish and hole quality. For application support or to verify suitability for specific materials and cutting conditions, Metav Werkzeuge offers technical consultation and documentation.

FAQ

What materials can be machined with this insert?
The suitability for specific materials must be checked in the product matrix; the P4840C-7R-E67 WXP40 is an uncoated carbide grade provided in Walter’s open series and requires matching to the workpiece material.

How does the 7R‑E67 chipbreaker improve machining?
The 7R‑E67 chipbreaker promotes controlled chip formation and fracture during drilling/boring, reducing entanglement and interruptions in production when used with appropriate cutting conditions.

Can the insert be indexed to a fresh cutting edge?
Yes, as an indexable insert the P4840C‑7R‑E67 allows rotation to a new cutting edge, which shortens downtime compared with full tool replacement and supports repeatable alignment.
