SNMA 120404 T5115 — Square ISO turning insert, CVD‑coated carbide — Tungaloy

SNMA 120404 T5115 is an ISO‑standard square turning insert designed for external and internal turning of cast components, offering a balance of wear resistance and edge stability

• ISO‑compliant square insert 12 mm
• CVD‑coated carbide grade T5115
• 0° relief angle for axial engagement
• Cylindrical hole for secure clamping

Consistent geometry for predictable machining results

The SNMA120404 T5115 insert follows the ISO form series for indexable turning, which simplifies tool planning and spare‑part logistics. Standardised geometry ensures repeatable seat and clamping characteristics when paired with compatible holders, reducing setup-related variation. The ISO conformity also supports machine programming consistency and makes it easier to select alternative inserts with matching form and tolerance classes. The CVD‑coated carbide substrate provides a layer that raises wear resistance under typical cast‑iron cutting conditions while preserving a stable cutting edge.

Balanced grade and edge design for cast‑iron turning

The T5115 grade has been engineered as a universal option for cast iron, offering an even compromise between longevity and edge robustness. This allows quieter transitions between roughing and light finishing without immediate edge chipping. The absence of an integrated chipbreaker on this insert makes it important to match tool geometry and cutting parameters to the component and machining strategy; when a defined chip form is required, a dedicated chipbreaker or tailored machining pass should be selected. The 0° relief angle and corner radius 0.4 mm help maintain contact stability on interrupted cuts and support predictable tool life.

Compact dimensions and secure clamping reduce downtime

The insert’s 12 mm nominal size and 4.76 mm plate thickness are optimised for common square‑format holders, providing a large bearing surface for clamping and a rigid cutting interface. The square form with a cylindrical hole allows positive axial and radial location in many standard carrier designs, improving repeatability across indexings. The geometric combination supports low‑vibration engagement at a 90° approach, which is advantageous for facing operations and short overhang setups where rigidity and dimensional control matter.

Practical advice for stable, cost‑effective turning

Selecting the correct holder, clamp set and fastening torque is decisive for the insert’s performance: matching the insert form and tolerance to the toolholder avoids unwanted micro‑movements and premature wear. As an indexable insert in an ISO series, the component benefits from straightforward rotation and replacement, which lowers machine downtime and supports predictable maintenance cycles. For complex parts or uncertain material mixes, technical consultation is recommended to tune feed, speed and depth of cut to the application and to choose a suitable chip control strategy.

FAQ

What materials is this insert suited for? The SNMA 120404 T5115 insert (Tungaloy, SKU 6853005‑Tungaloy) is optimised as a universal grade for machining cast iron, offering a balance of wear resistance and edge stability.

Does the insert include a chipbreaker? This insert is supplied without an integrated chipbreaker; chip control must be achieved with an appropriate holder design, machining parameters or a dedicated chip‑control insert alternative.

Which holders are compatible with this insert? Compatibility depends on holder form, relief angle, tolerance class, fastening method, size and thickness; use ISO‑compliant square carriers sized for 12 mm inserts for reliable seating.

How does the coating affect performance? The CVD coating enhances wear resistance under typical cast‑iron cutting regimes, helping to maintain edge integrity and extend effective tool life during production runs.

Is the corner radius suitable for finishing? The 0.4 mm corner radius provides a compromise between strength and surface finish, suitable for semi‑finishing and certain finishing passes when paired with appropriate feeds and speeds.
