SNMG120412 T505 — ISO indexable insert for turning; CVD-coated carbide, double-sided chipbreaker — Tungaloy

The SNMG120412 T505 is an ISO-format, square indexable insert designed for economical external and internal turning of cast iron, featuring a double-sided chipbreaker and a cylindrical-hole fixing for secure mounting

• CVD-coated carbide for durable cutting
• Optimised for cast iron machining
• Double-sided chipbreaker for stable chips
• 1.2 mm corner radius, 90° square form

Reliable performance for economical cast-iron turning

The insert is manufactured in a CVD-coated carbide grade, which is engineered to combine wear resistance with predictable flank behaviour; this results in reliable cutting performance when machining cast iron. The T505 grade is selected for economic machining, meaning that edge life and cutting speed are balanced to reduce tool costs per component. Because the coating and substrate interaction is optimised, stable chip control is achieved even under interrupted cuts, which supports consistent cycle times and reduces secondary processing.

Precise compatibility and secure clamping for stable operation

Designed to ISO geometry, the square 90° form and the cylindrical-hole fixing ensure compatibility with standard external holders and boring bars; compatibility is determined by form, relief angle, tolerance class, fixing method, size and thickness. The insert has a 0° relief angle, a 4.76 mm plate thickness and a 12 mm inscribed circle, while the 1.2 mm corner radius gives a balance between strength and edge definition. For a complete system, the insert is used with a suitable holder, underlay/clamping set and replacement screws, which together provide the rigidity required for repeatable turning results.

Productivity gains through chipforming and long tool life

The double-sided chipbreaker geometry is intended to control chip flow and reduce re-cutting, which leads to improved surface finish and reduced downtime from chip-related issues. As the insert is double-sided, it offers cost-efficiency through reversible use, extending the number of available cutting edges per insert. The combination of grade and geometry supports economical machining by permitting higher material removal rates in many cast-iron applications while maintaining good edge life. Where process reliability matters, the insert will deliver reproducible results across batches, contributing to predictable production planning.

FAQ

What materials is this insert suited for?
The SNMG120412 T505 insert is optimised for machining cast iron; the T505 grade with CVD coating provides the wear resistance and chip behaviour required for such applications.

How is the insert mounted in a holder?
The insert uses a cylindrical-hole fixing and an ISO square form; it is secured in compatible external holders or boring bars, together with an underlay and clamping set, to ensure stable clamping.

Can the insert be used on both external and internal turning operations?
Yes, the ISO-format geometry and 90° square form make the insert suitable for both external and internal turning when matched with the appropriate holder and machining parameters.

What are the dimensions I should check for holder compatibility?
Key dimensions include the inscribed circle of 12 mm, plate thickness 4.76 mm, and corner radius 1.2 mm; matching form, tolerance class and relief angle is essential for correct fit.

Does the insert support interrupted cuts?
The combination of CVD-coated carbide and the double-sided chipbreaker offers good chip control and robustness for many interrupted-cut scenarios, improving process reliability.
