SNMG 120412 T9225 indexable insert for Turning — Tungaloy

The SNMG120412 indexable insert is a CVD‑coated carbide grade designed for robust, universal use in external and internal turning of steel, offering toughness for interrupted cuts and fluctuating engagement conditions

• CVD‑coated carbide T9225 for toughness
• ISO SNMG120412 geometry for universal use
• Double‑sided chipbreaker for consistent chips
• 1.2 mm corner radius and 90° approach angle

Reliable performance for medium‑to‑heavy steel turning

The combination of CVD coating and a T9225 carbide substrate provides a balanced mix of wear resistance and toughness suited to medium‑to‑heavy turning operations. The coating reduces flank wear and improves resistance to built‑up edge, while the substrate toughness helps absorb shocks during interrupted cuts. As a result, the insert sustains longer effective tool life and steady dimensional accuracy, which benefits batch production and mixed‑lot machining where conditions vary between passes.

Secure mounting and ISO compatibility for workshop systems

Designed to the ISO standard SNMG120412, the insert’s square form with a cylindrical hole and a 4.76 mm thickness ensures predictable fitment in matching holders. Compatibility depends on form, clearance angle, tolerance class, attachment method, size and thickness; appropriate selection of the matching insert holder, shim/clamp set and replacement screws completes the system. Clear specification of geometry and mounting details simplifies tool changing and reduces setup time on lathes and turning centres, promoting reproducible clamping and cutting conditions.

Controlled chips and consistent surface quality

The double‑sided chipbreaker geometry delivers reliable chip control over a range of feeds, resulting in safer chip evacuation and more consistent surface finish. Stable chip formation reduces the risk of rework and tool interference, improving process reliability and productivity. For operations that demand repeatable results, the insert’s 1.2 mm corner radius supports a good balance between strength and edge contour, helping to maintain component tolerances while enabling effective material removal rates.
