SPMW070308-A88 WKM Wendeplatten - Walter Tools

Reliable productivity and predictable edge life result from the combination of the WKM coated-carbide grade and the A88 chipbreaker, while the 11° clearance and 0.8 mm corner radius support fine surface finishes and low cutting forces; order the insert directly via Metav Werkzeuge or consult our specialists for tailored machining advice.

SPMW070308-A88 WKM – Milling indexable insert, A88 chipbreaker, coated carbide (Walter Tools)

SPMW070308-A88 WKM offers a robust solution for finishing and semi-finishing milling operations where consistent chip control and reliable edge life are required.

• Coated carbide grade WKM
• A88 chipbreaker for stable chip control
• 11° clearance for lower cutting forces
• 0.8 mm corner radius for superior surface quality

Boosted process security through consistent cutting performance

The combination of the WKM grade and a dedicated A88 chipbreaker is designed to deliver predictable tool life and reduced process variability. The coated-carbide formulation provides wear resistance under typical milling conditions, which translates into fewer interruptions for edge changes and a steadier production flow. The chipbreaker geometry actively controls swarf formation, reducing the risk of built-up edge and helping to maintain a consistent cutting profile. For operations where cycle-time reliability and repeatable results matter, this insert supports improved throughput and lower per-part tooling costs.

Precision finishing with low forces and fine edge preparation

The insert’s 11° clearance angle and 0.8 mm corner radius are chosen to balance cutting stability and surface quality. A moderate clearance reduces friction at the flank face, lowering cutting forces and promoting dimensional stability of the workpiece. The square 90° form provides versatility for face and shoulder milling, while the small corner radius assists in producing fine surface finishes with controlled micro-geometry. Together these geometric features enable accurate component tolerances and minimise secondary finishing in many applications where surface integrity is essential.

Practical selection and application advice for varied workpiece materials

Material suitability is catalogue-dependent and should be checked against the detailed product matrix for optimal performance. The insert is offered in a coated hardmetal composition appropriate for a broad range of tasks; however, cutting parameters and coolant strategy must be matched to the workpiece and machine setup. Where uncertainty exists about the right grade, chipbreaker or parameter set, the application-oriented data and machining tables should be consulted. For precise recommendations on speeds, feeds and holder compatibility, technical consultation is available to ensure the insert’s capabilities are aligned with production goals.
