SPMN 090304 T5115 – Square indexable turning insert, CVD-coated carbide | Tungaloy

The SPMN090304 T5115 indexable insert is designed for general external and internal turning, offering a universal grade optimised for cast iron and compatibility with ISO toolholders.

• CVD-coated carbide grade T5115
• Universal grade for cast iron machining
• ISO format SPMN 090304 compatible
• Corner radius 0.4 mm, 11° clearance

Durable wear performance for cast iron machining

The CVD-coated carbide composition of this insert provides wear resistance and thermal stability during interrupted and continuous cuts in cast iron. The T5115 grade combines a hard coating with a tough substrate to maintain a stable cutting edge, reducing flank wear and extending index life under typical turning feeds and speeds. In production environments where repeatable part quality matters, the optimised coating-substrate pairing helps to maintain consistent tool life and surface finish, contributing to lower tooling costs per part and improved process reliability.

Secure fit and system compatibility for fast tool changes

Built to the ISO format SPMN 090304, the insert ensures consistent seating and orientation in standard holders. The square form delivers four usable cutting edges, enabling quick rotation to a fresh edge and minimised downtime. The standardised dimensions and tolerances support predictable clamping behaviour in compatible indexable insert holders, while the absence of a centre hole simplifies certain clamping systems. This predictability supports efficient tool management and straightforward spare-part logistics on the shop floor.

Geometry focussed on edge stability and surface quality

A corner radius 0.4 mm and an 11° clearance angle combine to provide a compromise between edge strength and surface finish. The moderate corner radius improves edge stability during heavier cuts, whereas the clearance angle reduces rubbing and improves chip flow. With a 3.18 mm thickness and a 90° included angle, the body of the insert contributes to rigidity in the cutting zone, supporting dimensional accuracy and repeatable results across batches. The geometry is therefore suited to operations that demand both durability and acceptable surface integrity without complex setup.

Practical guidance for integration and grade selection

When integrating this insert into a workflow, pair the ISO SPMN unit with an appropriate square holder and matching shim/clamping set to ensure correct rake and stability. Although this grade is a universal solution for cast iron, selecting a chipbreaker or alternative grade may further improve chip control for specific cast types or cutting conditions. The straightforward composition and ISO compliance of the insert support process optimisation: fewer tool changes, easier inventory handling and stable cycle times, which together raise productivity and process security on the machining centre.

FAQ

What materials is this insert best suited for?
The insert is designed as a universal grade for cast iron machining; the T5115 grade balances wear resistance and edge stability for a wide range of grey and ductile cast irons.

Is the insert compatible with standard ISO holders?
Yes, the SPMN 090304 designation denotes ISO compatibility; the insert fits holders designed for the SPMN 09 format and can be used with matching shims and clamping sets.

What are the key geometry values to consider for setup?
Important geometry values include the corner radius 0.4 mm, 11° clearance angle and 3.18 mm thickness, which together influence edge strength, chip flow and rigidity in the tool assembly.

Does this insert include a chipbreaker?
This version is specified without chipbreaker; chip control will depend on the paired holder geometry and cutting parameters.

How many cutting edges does the square form provide?
The square form offers four usable cutting edges per insert, enabling efficient index changes and extended service life before replacement.
