SEHW1204AFN WTP35 — Milling Insert (square 90°, coated carbide) by Walter Tools

The SEHW1204AFN WTP35 is a coated carbide milling insert designed for general milling tasks where a robust square geometry and reliable cutting behaviour are required.

• Coated carbide grade WTP35
• Square 90° insert form
• 20° relief angle for versatile milling
• 12 mm insert size, thickness code 04

Reliable performance from a coated carbide grade

The choice of the WTP35 coated carbide grade provides a balance between wear resistance and toughness. In practice, this means the insert is intended to deliver consistent cutting performance across a range of jobs; wear develops predictably and tool change intervals can be planned. The specification indicates a coated hardmetal composition, which improves resistance to abrasion and edge breakdown compared with uncoated grades. For production planning, the predictable behaviour of a coated grade supports efficient cycle scheduling and helps to reduce unplanned downtime.

Stable geometry for demanding milling operations

A square 90° form combined with a 20° relief angle makes this insert suitable where rigidity and full-corner strength are priorities. The square shape gives multiple usable cutting corners, improving indexable life per insert, while the specified relief angle supports effective engagement in both shoulder and slot milling. The 12 mm designation with thickness code 04 describes a compact, robust insert that is easy to handle and index. These mechanical characteristics are chosen to maintain cutting edge stability under medium to heavy feed conditions, supporting repeatable part quality.

Designed for workshop and production environments

As an indexable milling component, the SEHW1204AFN series is intended for secure clamping and fast replacement, which reduces non-productive time during tool changes. The insert’s coated surface contributes to reduced built-up edge and improved surface finish on workpieces when machining compatible materials. Material suitability should be verified against the product matrix: the grade is described as a coated hardmetal, and compatibility with specific metals must be checked before series production to ensure optimal cutting parameters and tool life.

Practical integration and cutting data guidance

Integration into existing toolholders and tool systems is straightforward where the geometry code matches the holder design. Because tooling decisions depend on machining strategy and workpiece material, the product data emphasises checking the manufacturer’s matrix for recommended applications. For process optimisation, providing the machine type, workpiece material and target surface quality will enable the determination of suitable cutting speeds and feeds for the SEHW1204AFN WTP35, helping to secure predictable throughput and cost-efficiency.

FAQ

What materials is this insert suitable for?
Material suitability must be verified in the product matrix; the SEHW1204AFN WTP35 is a coated hardmetal grade intended for a range of applications and should be matched to the specific workpiece material.

How many cutting edges are available per insert?
The square 90° geometry provides multiple usable corners; the exact count depends on the insert indexing practice and whether all corners are used for the intended operation.

Is the SEHW1204AFN WTP35 compatible with standard Walter toolholders?
The insert follows common ISO geometry coding and is compatible with toolholders designed for that insert form; correct seat and clamp verification is recommended before use.

What benefit does the 20° relief angle offer?
A 20° relief angle balances cutting edge strength with clearance, supporting robust engagement in shoulder and slot milling while helping to maintain surface quality.

Where can cutting data for this insert be obtained?
Cutting parameters and recommended feeds are available from Metav Werkzeuge or the manufacturer’s technical documentation; consult the product matrix for material-specific data.
