SNMG120404 T9215 square indexable turning insert — CVD-coated carbide, 0.4 mm radius — Tungaloy

The SNMG120404 T9215 is a square, ISO-standard indexable insert engineered for general external and internal turning, optimised for productive machining of medium steels.

• CVD-coated carbide grade T9215
• 0.4 mm corner radius for robust edges
• Double-sided chipbreaker for stable chip control
• ISO-compliant form for wide holder compatibility

Productivity through a wear-resistant CVD coating

The CVD-coated carbide grade T9215 combines high wear resistance with dependable fracture toughness, making it well suited to sustained production runs on medium-strength steel. This grade is designed to maintain cutting performance in both continuous and lightly interrupted cuts, which reduces unscheduled downtimes and contributes to a predictable tool-life curve. The result is a cost-effective cutting edge that supports consistent cycle times and fewer insert changes.

Geometry that balances surface finish and tool life

A square plate with a 0.4 mm corner radius and an included angle of 90° offers a compromise between edge strength and achievable surface quality. The modest corner radius increases resistance to chipping under heavier engagement, while still permitting fine surface finishes when set up accordingly. The double-sided chipbreaker aids controlled chip formation, reducing the risk of long, entangling swarf and helping to maintain stable cutting forces during each pass.

ISO compatibility for straightforward integration

As an ISO-standard turning insert from the ISO turning insert series, the component integrates easily with matching holders provided the form, relief angle, tolerance class, fastening and thickness are respected. Its 4.76 mm plate thickness and 12 mm inscribed circle are typical dimensions that allow selection from a broad range of compatible external or boring holders. Clear specification of these parameters makes tool changeovers predictable and simplifies inventory management on the shop floor.

Practical application and handling benefits

The insert’s cylindrical hole and standard hole style enable secure fastening and indexing in suitable clamps or screw systems. Being double-sided, it offers multiple usable edges per insert, improving cost-per-edge performance. For workshop planners, this means fewer tool assemblies to manage and improved uptime. When selecting cutting parameters, prioritise stable clamping and appropriate feed rates to exploit the grade’s performance while preserving edge life.

FAQ

What materials is this insert suited to machine?
The Tungaloy SNMG120404 T9215 insert is optimised for medium steel machining, delivering a balance of wear resistance and edge toughness appropriate for continuous and lightly interrupted cuts.

Is the SNMG120404 indexable and reversible?
Yes, the SNMG120404 is a double-sided indexable insert; the design provides multiple cutting edges that can be indexed to extend overall tool life.

How does the T9215 grade improve productivity?
The T9215 CVD coating offers improved wear resistance and chipping resistance, enabling higher productivity with steadier performance over longer tool-life intervals.

What dimensions and geometry determine holder compatibility?
Compatibility depends on plate form, inscribed circle (12 mm), plate thickness (4.76 mm), relief angle and fastening style; ensuring these match the chosen holder secures repeatable seating and performance.

Can this insert be used for internal turning?
Yes, the geometry and ISO standardisation allow application in both external and internal turning operations when paired with a suitable boring bar or holder.
