SNMG120408 T505 SNMG Turning Insert by Tungaloy

SNMG120408 T505 — a square ISO turning insert designed for economical and stable machining of cast iron components in general turning applications.

• CVD-coated carbide grade T505
• Square 12 mm insert with 0.8 mm radius
• Double-sided chipbreaker for consistent chips
• Cylindrical-hole design for secure clamping

Efficient machining performance for cast iron

The CVD-coated T505 grade is formulated to deliver economical machining of cast iron, balancing wear resistance and edge stability. The coating increases surface hardness and thermal resistance, which contributes to longer edge life under intermittent cuts and varying cutting speeds. As a result, cycle times can be reduced without compromising workpiece finish, and production runs experience fewer interruptions due to insert changes. This combination makes the insert a practical choice where machining cost per part and process stability are priorities.

Secure fit and ISO compatibility for predictable setups

The insert follows the ISO SNMG120408 geometry and the square format provides four usable cutting edges, supporting cost-effective indexing strategies. Compatibility with holders is determined by form, relief angle, tolerance class, fastening and thickness; the presence of a cylindrical hole simplifies positive location and clamping in standard external holders or boring bars. With a plate thickness of 4.76 mm and a nominal size of 12 mm, the insert integrates into common tool systems, enabling predictable repeatability and fast changeover in production environments.

Chip control and application focus for turning operations

Equipped with a double-sided chipbreaker, the insert produces consistent, manageable chips during both external and internal turning. The 0° relief angle and an approach angle of 90° offer a neutral cutting geometry that suits a broad range of turning tasks on cast iron, including finishing and semi-finishing operations. Stable chip formation reduces the risk of surface blemishes and tool nose damage, supporting higher effective feed rates and steady component quality. For interrupted cuts or less rigid set-ups, select the chipbreaker and grade to match the workpiece and machining strategy.

Practical benefits and selection guidance

Using a carbide indexable insert of this type streamlines inventory and simplifies process planning: four indexed edges per insert, CVD protection for thermal resilience, and a standard ISO form for broad holder availability. When specifying the insert, consider the grade T505 for cast iron applications and align feed, depth of cut and cutting speed with machine rigidity to maximise tool life and productivity. For complex or critical components, consult the technical advisers to match holder geometry and clamping arrangement with the insert’s dimensions and hole style.

FAQ

What materials is this insert best suited for?
The SNMG120408 T505 insert (Tungaloy, SKU 6831323-Tungaloy) is optimised for cast iron machining; the CVD-coated carbide grade provides a balance of wear resistance and cost efficiency.

Can this insert be used for internal and external turning?
Yes, the indexable design and chipbreaker geometry support both external and internal turning operations when paired with the appropriate holder and clamping arrangement.

How many cutting edges are available per insert?
The square SNMG geometry provides four usable cutting edges per insert, enabling economical indexing and reduced tooling costs over time.

What are the key dimensions to check for holder compatibility?
Verify the ISO form SNMG120408, plate size (12 mm), thickness (4.76 mm), corner radius (0.8 mm) and the presence of a cylindrical hole to ensure correct seating and clamping in the chosen holder.

Is the insert suitable for interrupted cuts?
The T505 grade and robust geometry offer reasonable performance in interrupted cuts on cast iron, but machine rigidity and cutting parameters should be adjusted to the specific application.
