SPMR 120304 T5115 — ISO turning insert, CVD-coated carbide, Tungaloy

The SPMR120304 T5115 is an ISO-standard square turning insert designed for external and internal turning, optimised for cast iron with a one-sided chipbreaker and a 0.4 mm corner radius.

• ISO SPMR 120304 geometry, square insert
• CVD-coated carbide grade T5115
• One-sided chipbreaker for cast iron
• 0.4 mm corner radius for stable edges

Reliable chip control for consistent productivity

The square indexable insert provides a predictable cutting edge and repeatable results in turning applications. The CVD-coated carbide composition of the grade ensures a balanced combination of wear resistance and edge stability, which reduces downtime caused by unexpected tool changes. With an integrated one-sided chipbreaker, chip formation is controlled even in interrupted cuts, supporting a smoother material flow and lower risk of surface defects. This results in more consistent cycle times and improved process reliability for series production.

Compatibility and straightforward tool selection

Designed to the ISO plate family, the geometry and dimensions follow international standards, making holder matching systematic. Key dimensions such as the 12 mm plate size, 3.18 mm thickness and the 11° relief angle define compatibility with a wide range of external holders and boring bars. Because form, free angle, tolerance class, fastening style, size and thickness determine fit, pairing the insert with the correct clamping set and screw ensures secure seating and repeatable positioning. This approach reduces setup time and supports predictable tool life.

Optimised for cast iron with industrial-grade backing

The T5115 grade is a universal choice for cast iron, offering a compromise between long life and durable cutting edges. The cemented carbide substrate with its CVD layer is tuned for abrasive grey and nodular cast iron varieties, improving surface finish while maintaining edge strength. The 0.4 mm corner radius contributes to robust edge support, reducing chipping on tougher batches and enabling slightly heavier depth-of-cut strategies where process stability is prioritised over fine finishing.

Practical benefits for workshop efficiency

Using a standardised insert family simplifies inventory and reduces variant complexity on the shop floor. The square form allows four indexing positions, extending usable life per insert and lowering cost per cut. Clear, measurable characteristics such as the 90° cutting angle and the defined relief and thickness make programming and fixture planning more straightforward. Where faster turnaround and predictable outcomes matter, this insert supports efficient machining cycles and easier quality control.

FAQ

What materials is this insert best suited for?

The T5115 grade insert from Tungaloy is optimised for cast iron machining, offering a balanced mix of wear resistance and edge stability for grey and nodular cast irons.

How many cutting edges are available per insert?

As a square ISO insert, the SPMR120304 format provides up to four indexable cutting positions before replacement is needed.

Which holders are compatible with this insert geometry?

Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness; Metav Werkzeuge can advise on suitable external holders and boring bars for the SPMR120304 T5115.

What advantage does the 0.4 mm corner radius provide?

The 0.4 mm corner radius increases edge support, reducing chipping risk and enabling more stable cuts where edge robustness is required.

Is this insert supplied with mounting screws or clamping sets?

The supply concept for ISO turning systems typically comprises the insert, a matching external holder or boring bar, underlay/clamping set and replacement screws; check the specific order configuration for included parts.
