SNMG120412 T5115 SNMG turning insert — CVD-coated carbide for cast iron | Tungaloy

The SNMG120412 T5115 is an ISO-standard turning insert designed for external and internal turning operations, offering a universal CVD-coated carbide grade optimised for cast-iron machining.

• CVD-coated carbide T5115 for cast iron
• Double-sided chipbreaker for consistent chips
• Square form with cylindrical hole for secure mounting
• 1.2 mm corner radius and 0° clearance angle

Consistent cutting performance where cast iron matters

The combination of a CVD-coated carbide substrate and the T5115 grade provides a balanced mix of wear resistance and edge stability tailored for cast-iron machining. The coating reduces flank wear at higher cutting speeds and helps maintain a stable cutting edge over successive indexed positions, which supports predictable process windows in production. This makes the insert suitable for batch runs and repeatable turning tasks where surface finish and dimensional stability are priorities.

Secure fit and form for reliable toolholding

Manufactured to the ISO SNMG120412 geometry, the insert features a square form, cylindrical hole, and a nominal plate thickness of 4.76 mm, which together determine compatibility with a wide range of external holders and boring bars. Compatibility depends on form, relief angle, tolerance class, fastening method, size and thickness, so the insert sits securely in the pocket and transmits cutting forces reliably. The 0° relief angle and 90° included angle suit a broad set of holder types for general turning.

Efficient chip control and application guidance

The double-sided chipbreaker design supports controlled chip formation when turning cast iron, reducing potential for tangled chips and easing automated handling. With a 1.2 mm corner radius, the insert balances robustness and edge strength against the need for fine surface finishes. Typical uses include finishing and medium turning of cast-iron components; selection of a matching chipbreaker and grade ensures optimal performance depending on workpiece stability and cutting parameters.

FAQ

What materials is this insert best suited for?
The SNMG120412 T5115 insert is formulated as a universal grade for cast iron, providing a balance of wear resistance and edge stability specifically for cast-iron turning.

How does the T5115 coating affect cutting performance?
The CVD coating on the T5115 grade improves wear resistance and helps maintain a stable cutting edge at elevated speeds, which benefits surface finish and reproducibility when using the SNMG insert.

Is the insert compatible with standard SNMG holders?
Yes, the SNMG120412 geometry conforms to ISO SNMG standards; compatibility with a holder depends on form, clearance, tolerance class, fastening method, size and thickness.

What is the corner radius and why does it matter?
The corner radius is 1.2 mm; a larger radius enhances edge strength and reduces the risk of chipping, while still allowing good surface finish in many turning operations.

Can this insert be used for internal turning?
The insert can be employed for both external and internal turning, provided the selected holder or boring bar accommodates the SNMG120412 form and dimensions.
