SPMR 090308 T5115 – Turning indexable insert SPMR for ISO turning by Tungaloy

A robust SPMR090308 T5115 indexable insert engineered for ISO-standard holders, optimised for external and internal turning in cast iron applications.

• CVD-coated carbide grade T5115
• ISO SPMR090308, square 09 format
• 11° relief angle for stable cutting
• Single-sided chipbreaker with 0.8 mm radius

Consistent integration and material compatibility for turning operations

The ISO-standard format ensures straightforward integration of this indexable insert into existing tool systems: compatibility depends on insert form, relief angle, tolerance class, fastening method, size and thickness. The CVD-coated carbide substrate provides an optimised balance between wear resistance and edge stability, which is especially beneficial when machining cast iron. With a plate thickness of 3.18 mm and a corner radius of 0.8 mm, the geometry supports predictable cutting forces and dimensional stability, reducing the need for frequent tool changes and supporting steady production flow.

Improved process reliability and surface quality

The single-sided chipbreaker design promotes controlled chip formation and evacuation, which helps to maintain consistent surface finish and reduces the risk of built-up edge in interrupted or unstable cuts. The universal grade T5115 is formulated for broad cast-iron coverage, offering longer cutting intervals and dependable edge life under typical turning parameters. These characteristics translate into higher machine uptime and lower tooling costs per part when compared with unoptimised combinations of insert and grade.

Practical handling and system setup for efficient shop-floor use

Mounting the indexable insert is straightforward when the correct holder or boring bar is selected: ensure form and fastening match the insert geometry, and keep a suitable clamp kit and spare screws available for quick changeovers. For external and internal turning operations, choose the chipbreaker and grade according to workpiece stability and desired surface specification; selecting a more stable setup allows for higher cutting data, while reduced overhang helps maintain dimensional accuracy. The insert’s square shape (format 09) provides four cutting edges per index, supporting economical edge utilisation in series production.

FAQ

What materials is this insert best suited for?
This insert is a universal grade optimised for cast iron machining; the CVD-coated carbide and T5115 formulation balance wear resistance and edge stability for reliable turning.

How does the insert fit into existing toolholders?
Compatibility is determined by insert form, relief angle, tolerance class, fastening type, size and thickness; the ISO SPMR090308 geometry fits ISO-standard SPMR holders when matched accordingly.

What are the key geometric specifications of this insert?
Notable dimensions are 3.18 mm plate thickness, 0.8 mm corner radius and an 11° relief angle, which together influence cutting stability and edge strength.

Can the insert be used for internal turning or boring?
Yes; the insert supports both external and internal turning when used with a suitable boring bar or internal holder that matches the SPMR format and clamping method.

How many cutting edges are available per insert?
The square 09 format provides up to four usable cutting edges per insert when rotated and re-seated according to the holder’s clamping specification.
