CNMG120402-FP5 WEP10C — Turning insert, Rhombus 80°, 0° negative — Walter Tools

The CNMG120402-FP5 WEP10C is a cermet turning insert designed for precision finishing and controlled chip formation in medium‑duty turning operations

• Walter Cermet grade WEP10C
• FP5 chipbreaker for controlled chip formation
• Rhombus 80° insert geometry
• 0° negative rake with 0.2 mm corner radius

Predictable finishing and edge performance

The cermet composition of this insert, specified as WEP10C, is engineered for stable cutting edges and improved surface quality during finishing cycles. Combined with the FP5 chipbreaker, the geometry promotes regular chip segmentation and reduces the risk of long, stringy chips that compromise surface integrity. Thanks to tolerance class M, the insert offers consistent fit and repeatability in standard toolholders, which supports process stability across production runs. For definitive material recommendations, the product matrix should be consulted before application.

Geometry tailored for secure engagement and fine contours

The Rhombus 80° form delivers a compact seating area with access to tight internal profiles while keeping a robust cutting edge. The 0° negative rake increases edge strength and reduces the tendency for edge chipping under intermittent loads, making the geometry suitable where a balance of accessibility and durability is needed. A 0.2 mm corner radius provides a controlled cutting radius for fine turning and helps maintain surface finish without excessive tool pressure. Plate size 12 and thickness 04 ensure compatibility with commonly used CNMG toolholders for finishing operations.

Integration into productive machining setups

As part of the Walter Cermet series, this insert supports consistent batch processing where predictable edge life and surface finish matter. The CNMG120402-FP5 WEP10C is produced to catalog specifications; material details are catalogue dependent and should be checked against the workpiece requirements. The combination of grade, chipbreaker and geometry is oriented towards finishing and semi‑finishing strategies where controlled chip flow and repeatability translate directly into fewer tool changes and steadier part quality. For specific cutting data and recommended operating windows, refer to the technical sheet or the product matrix.

FAQ

What is the main application for this insert?
The CNMG120402-FP5 WEP10C is intended primarily for precision finishing and semi‑finishing turning tasks where cermet grades and a controlled chipflow are required.

How does the FP5 chipbreaker affect chip behaviour?
The FP5 chipbreaker promotes segmented, controllable chips that aid consistent surface quality and reduce interruptions caused by long, stringy chips during turning operations.

What advantage does a 0° negative rake provide?
A 0° negative rake increases edge stability and robustness, improving resistance to edge chipping under interrupted cuts or tougher cutting conditions.

What does tolerance class M indicate for workshop use?
Tolerance class M denotes standardised dimensional tolerance for the insert, supporting interchangeability and repeatability when mounted in compatible toolholders.

How is the insert specified in ISO terms?
The ISO designation is CNMG120402-FP5 WEP10C, reflecting the insert shape, size, chipbreaker and the cermet grade.
