SEHT1204AFN-K88 WK10 milling indexable insert — square 90°, 20° relief (Walter Tools)

The SEHT1204AFN-K88 WK10 is a square milling insert engineered for stable medium‑duty milling and finishing applications in workshop and production settings.

• Uncoated carbide grade WK10
• K88 chipbreaker for reliable chip control
• Square 90° shape for versatile milling
• 20° relief angle for stable cutting

Consistent cutting performance for dependable productivity

This indexable insert employs the WK10 uncoated carbide grade and a dedicated K88 chipbreaker to deliver steady cutting forces and predictable wear behaviour. The square 90° geometry offers a robust cutting edge and multiple indexing positions, which extends tool life and reduces tooling changes. With a 20° relief angle the insert maintains a favourable cutting geometry that helps to reduce rubbing and heat generation, resulting in a consistent metal‑removal rate and fewer interruptions to the production flow. These characteristics translate into measurable process stability and lower unit costs in batch production.

Precise chip control for improved surface quality

The engineered chipbreaker ensures controlled fragmentation and evacuation of swarf, promoting a cleaner cutting zone and better coolant access. Improved chip control yields a more consistent surface finish and reduces secondary work such as deburring. For machining tasks where repeatability and component quality matter, this insert supports shorter cycle times and fewer rejects. Note that the grade is uncoated, which offers economical performance for a wide range of applications; compatibility with specific workpiece materials should be checked against the manufacturer’s product matrix.

Efficient handling and repeatable setup for shopfloor confidence

Designed with a tolerance class of H and execution code T, the insert fits standard indexable toolholders and enables fast, repeatable insert changes that save setup time. The item belongs to the Walter Schneidstoffsorte open series, which simplifies grade selection and inventory management. As the material specification is catalogue‑dependent, the insert’s exact substrate and recommended cutting data should be verified in the technical documentation. The combination of a predictable grade, stable edge geometry and standardised form supports reliable operation across shifts and operators.
