SNMG120408 T515 SNMG — ISO turning insert for cast‑iron machining, CVD‑coated, 0.8 mm radius — Tungaloy

The SNMG120408 T515 is an ISO‑standard square turning insert designed for economical external and internal turning of cast iron, compatible with holders that match form, clearance angle, tolerance and thickness.

• ISO SNMG square insert, 90° geometry
• CVD‑coated carbide for cast‑iron machining
• Double‑sided chipbreaker, economical cut
• 0.8 mm corner radius; 4.76 mm thickness

Consistent wear resistance and improved chip control for cast‑iron work

The grade is a CVD‑coated carbide designed to deliver stable cutting performance when machining cast iron. The hard, wear‑resistant coating reduces crater wear and improves edge stability, which in turn extends tool life and reduces unplanned tool changes. The integrated chip control geometry — a double‑sided chipbreaker — assists in producing short, manageable chips even under interrupted cuts, improving process reliability and surface quality. For users seeking a balance of running time and repeatability, this insert offers a predictable, cost‑effective option for batch and series turning.

ISO compatibility and clear, measurable setup data for fast tool exchange

The insert follows ISO standards for shape and dimensions, allowing easy replacement within ISO‑spec holders when form, clearance and fastening match. Key specifications are plainly communicated for correct setup: insert size 12 mm, thickness 4.76 mm, corner radius 0.8 mm, lead/approach angle 90°, and a cylindrical hole for secure fastening. The nominal clearance angle is 0°, which affects engagement and recommended feed values. These measurable values simplify tool selection and reduce assembly time, while the standard geometry ensures consistent clamping behaviour across compatible toolholders.

Productivity gains from indexing capability and grade selection

The square, double‑sided design delivers multiple indexable cutting edges per insert, lowering cost per cutting edge and improving machine uptime. The double‑sided chipbreaker means each indexed position is ready for controlled cutting, so production flows with minimal intervention. Choosing the T515 grade aligns cutting speed and edge security with typical cast‑iron applications; pairing the insert with the correct holder and stable machining parameters yields better surface finish and fewer rework cycles. The result is economical, repeatable throughput suited to workshops and production lines where predictable output and process security matter.

FAQ

What materials is this insert suited for?
The SNMG120408 T515 is optimised for cast‑iron machining; the T515 grade and CVD coating provide abrasion resistance and stable cutting for grey and nodular cast irons.

How many indexable edges are available per insert?
The square, double‑sided design offers multiple indexable edges; the SNMG120408 T515 can be indexed to a fresh cutting edge when required, reducing cost per edge.

Which key dimensions should be checked for holder compatibility?
Check insert size 12 mm, thickness 4.76 mm, corner radius 0.8 mm, and the cylindrical hole; these determine fit and secure clamping for the SNMG120408 T515.

Is this insert suitable for interrupted cuts?
Yes, the CVD‑coated carbide and the double‑sided chipbreaker of the SNMG120408 T515 provide enhanced edge robustness and chip control, improving performance in intermittent cutting.

What is the manufacturer SKU for ordering and traceability?
The manufacturer SKU for this product is TUN6764416 and the supplier SKU is 6764416‑Tungaloy, which can be referenced when ordering the SNMG120408 T515.
