SNMG120408 T5105 indexable turning insert (square), Tungaloy — CVD‑coated carbide for turning

SNMG120408 T5105 is an ISO‑standard indexable insert designed for external and internal turning operations on cast iron where stable set‑ups allow high cutting speeds

• ISO-standard SNMG geometry
• CVD-coated T5105 carbide grade
• Designed for high-speed cast iron turning
• Cylindrical hole; double-sided chipbreaker

Enhanced efficiency through a wear‑resistant grade

The CVD‑coated T5105 carbide composition prioritises abrasion resistance under elevated cutting speeds, which translates into longer edge life and fewer tool changes. In practice, this means more productive machining cycles for stable turning operations and a more predictable tool-cost profile. The coating technology provides a hard, thermally resistant surface that reduces flank and crater wear, helping to maintain dimensional tolerances and consistent surface finish over extended runs.

Precise fit and secure clamping for repeatable use

The insert follows the ISO‑standard SNMG geometry and is supplied in a square form with a cylindrical hole, ensuring compatibility with a wide range of external holders and boring bars. The combination of 4.76 mm thickness, 12 mm inscribed circle and a 0° relief angle enables secure clamping and straightforward indexing. This defined geometry supports predictable seating and repeatable positioning, which reduces set‑up time and improves reproducibility across serial production.

Controlled chip formation and application suitability

A double‑sided chipbreaker and the insert’s geometry promote controlled chip formation when machining cast iron, reducing the risk of entanglement and improving surface integrity. The grade and chipbreaker design are optimised for cast iron turning under stable conditions; selecting the matching chipbreaker and cutting regime ensures efficient swarf control and reliable performance. The insert is particularly suited where clean chip batches and steady cutting forces are required to protect the tool and workpiece finish.

Practical handling and machining recommendations

With a 0.8 mm corner radius the insert balances edge strength and finish capability for typical finishing to medium‑depth turning passes. The square shape supports multiple indexing positions, enhancing cost efficiency per insert. For best results, a rigid toolholder and minimal vibration are recommended; this stabilises the cutting zone and allows the T5105 grade to deliver consistent results. Regular inspection of seat condition and correct torque on the fastening screw ensure repeatable clamping and longer service life.
