SNMG 190612 T515 Turning Insert (CVD-coated carbide, 90°) — Tungaloy

The SNMG190612 T515 is an ISO-standard indexable turning insert designed for efficient external and internal turning of cast iron components.

• CVD-coated cemented carbide grade T515
• Economical solution for cast iron machining
• Double-sided chipbreaker for versatile use
• 1.2 mm nose radius for reliable edge strength
• ISO SNMG190612 with 90° geometry and hole

High-performance grade for economic cast iron machining

The combination of a CVD-coated surface and a cemented carbide substrate, specified as the T515 grade, provides a balance of wear resistance and toughness that supports high material removal rates in cast iron applications. This configuration is optimised for stable chip formation and predictable tool life, which translates into lower tooling costs per part and fewer interruptions during production. The coating reduces flank wear and helps maintain a consistent cutting edge, so cycle times remain stable across batch runs.

Simple integration into existing ISO tool systems

The insert follows the ISO SNMG190612 format, ensuring straightforward compatibility with common external holders and boring bars. Compatibility is determined by geometry, relief angle, tolerance class, fastening and plate thickness, and this insert meets the ISO criteria for those parameters. Using standardised inserts reduces inventory complexity and simplifies holder selection, allowing machines to be retooled quickly and with minimal setup time. The standardised form factor supports predictable process implementation in mixed-production environments.

Enhanced edge strength and chip control for robust cutting

With a 1.2 mm nose radius and a double-sided chipbreaker, the insert delivers durable edge strength and effective chip control across a range of feeds and depths. The modest nose radius helps resist chipping during interrupted cuts while still permitting acceptable surface finish when light finishing passes are required. The 90° included angle concentrates cutting forces into stable contact, further supporting dimensional accuracy on external turning operations. The double-sided design provides multiple cutting edges per indexable unit, extending the usable life before disposal.

Practical system benefits and process reliability

The insert is supplied as part of a system that includes the insert itself, a compatible outer holder or boring bar, and the necessary clamping pads and screws for secure fixation. This systemic approach reduces installation errors and supports repeatable setups. For operations where intermittent cutting or varying workpiece stability occurs, choose the grade and chipbreaker suited to the specific cutting condition to maintain consistent performance. The overall result is improved uptime and predictable component quality, helping to meet production deadlines with confidence.

FAQ

Which materials is this insert suited for?
The SNMG190612 T515 insert is optimised for cast iron; the T515 CVD-coated grade offers the chip control and wear resistance required for economical machining of grey and nodular cast irons.

What are the key geometry details of the insert?
This SNMG190612 insert features a 90° included angle, a 1.2 mm nose radius, a square form with 19 mm size and a plate thickness of 6.35 mm, compatible with ISO SNMG holders.

Is the insert appropriate for interrupted cuts and unstable setups?
Yes — the combination of a robust 1.2 mm nose radius and a double-sided chipbreaker supports interrupted cuts; choose the insert grade and holder rigidity according to the extent of interruption and workpiece stability.

How many cutting edges are available per insert?
The double-sided design provides multiple indexable edges; rotating to a fresh edge restores cutting performance without changing the insert body.

What determines whether the insert fits a particular holder?
Compatibility depends on the insert form, relief angle, tolerance class, fastening method, size and plate thickness; these ISO-aligned parameters ensure proper seating and secure clamping in matching holders.
