P4840C-8R-E67 WXP40 indexable insert – drilling and boring, uncoated carbide, chipbreaker 8R‑E67 (Walter Tools)

The P4840C-8R-E67 WXP40 is an indexable insert intended for drilling and bore-enlargement applications, offering a robust chip control geometry and an uncoated hardmetal grade for general-purpose machining.

• Uncoated carbide grade WXP40
• Optimised 8R‑E67 chipbreaker
• Designed for drilling and boring
• Walter quality — reliable tool life

Stable chip control that keeps cycles running

The insert combines an uncoated carbide substrate with a precisely formed chipbreaker 8R‑E67 to deliver consistently stable chip formation in drilling and boring operations. The geometry channels chips reliably away from the cutting edge, reducing the risk of clogging and enabling continuous cutting at steady feed rates. For process engineers this means fewer interruptions on the machine and a more predictable production rhythm, which supports higher overall equipment effectiveness and contributes to faster part throughput.

Productive machining focused on process reliability

Engineered as an indexable insert within Walter's open series, the grade offers a balance between edge strength and wear resistance suited to a wide range of workpiece materials. The WXP40 grade is an uncoated hardmetal; suitability for specific alloys should be verified against the official product matrix. Where high surface quality and repeatable hole dimensions are required, the insert's geometry minimises vibration and promotes stable cutting forces, supporting consistent bore quality and reducing the need for rework.

Practical integration and workshop benefits

Integration into common drill and boring bodies is straightforward thanks to the standard designation and form. The insert's combination of productive machining characteristics and reliable edge performance tends to extend effective tool life, lowering tooling consumption and stabilising costs over production runs. For procurement and process planning, the catalogue notes that detailed substrate and coating information is catalogue-dependent, so matching the correct variant to the application ensures optimal results. The design therefore supports both everyday production tasks and demanding series work where repeatability is decisive.

FAQ

What materials is this insert intended for?
The P4840C-8R-E67 WXP40 insert is supplied in an uncoated hardmetal grade; the exact workpiece materials suitable for this grade must be checked in the product matrix to ensure the right match for the machining task.

Does the insert include a coating?
The cutting grade WXP40 is specified as an uncoated hardmetal in the product data for this insert; select coated alternatives if a specific coating is required for abrasive or high-temperature applications.

How does the 8R‑E67 chipbreaker affect performance?
The 8R‑E67 chipbreaker is engineered to promote controlled chip formation during drilling and boring, reducing clogging and stabilising cutting forces to improve hole quality and reduce cycle interruptions.

Is this insert compatible with standard drill bodies?
The insert uses a standard designation and form intended for drill and boring bodies that accept this type; compatibility should be confirmed against the holder type and clamping system in the tool assembly.
