SPMW 090308 T5115 — Tungaloy turning insert, CVD-coated carbide, square 90°

SPMW090308 T5115 Tungaloy insert for ISO‑standard turning, designed for versatile external and internal turning applications in cast iron

• CVD-coated carbide for extended life
• Square 90° geometry for robust turning
• Corner radius 0.8 mm for heavy cuts
• Cylindrical hole with single-side countersink

High wear resistance and balanced edge stability for cast iron

The SPMW090308 T5115 combines a CVD coating with a wear‑resistant carbide substrate to deliver a universal grade tailored for cast iron machining. The coating reduces abrasive wear while preserving the integrity of the cutting edge, which translates into longer tool life and fewer index changes. This technical combination supports stable cutting forces and predictable tool behaviour, which is essential when aiming for consistent cycle times and reduced spare‑part consumption in series production.

Predictable geometry for secure machining and surface quality

The square, 90° geometry and the corner radius 0.8 mm give high radial support and resistance to chipping, making the insert suitable for robust turning operations. With a relief angle 11° and a plate thickness 3.18 mm, the design provides the rigidity required for interrupted cuts and heavy feed rates while maintaining a quality workpiece surface. The ISO conformity ensures repeatable clamping and interchangeability across common external holders and boring bars, simplifying process planning and fixture selection.

ISO compatibility and clear mounting requirements

The insert follows the ISO‑insert system and depends on holder form, tolerance class, fastening and thickness for full compatibility. The configuration includes a cylindrical hole with a single‑side countersink (40°–60°) that secures clamping and torque transfer in the seat. For a complete cutting system, pair the insert with a suitable external holder or boring bar, a matching shim/clamping set and the correct replacement screws. Clear system understanding reduces setup time and minimises the risk of incorrect assembly in the workshop.

Productivity gains and inventory simplification

Using a universal grade like T5115 reduces the number of grades required on the shelf while delivering dependable performance across a broad range of grey and nodular cast irons. The robust cutting edge and consistent wear characteristics support longer tool life and fewer interruptions, directly improving machine uptime and process throughput. For manufacturers targeting repeatable part quality and optimised throughput, this insert offers a pragmatic route to lower tooling logistics and enhanced production reliability.

FAQ

What materials is this insert best suited for?
The SPMW090308 T5115 insert is formulated as a universal grade for machining cast iron; the T5115 composition balances wear resistance and edge stability for grey and nodular cast irons.

How does the insert mount to the holder?
The SPMW090308 T5115 uses a cylindrical hole with a single‑side countersink (40°–60°) to ensure positive clamping; pairing with an ISO‑compatible external holder and correct clamping set is required for safe use.

What cutting geometry delivers the best balance between life and finish?
The 90° square geometry with a corner radius of 0.8 mm and a relief angle of 11° provides rigidity for heavier cuts while maintaining surface quality in typical turning operations with the SPMW090308 T5115.

Is a chipbreaker included and when should it be used?
This insert is supplied without a chipbreaker; chip control should be managed via grade selection, insert geometry, and cutting parameters suited to the workpiece and operation.

Which SKU identifies this original Tungaloy insert?
The original Tungaloy item is listed as SKU 6862099-Tungaloy and manufacturer article number 6862099 for procurement and inventory purposes.
