SNMG120412 T515 Tungaloy – ISO indexable turning insert for turning

SNMG120412 T515 Tungaloy is an ISO-designated, square indexable insert engineered for efficient external and internal turning of cast iron components

• CVD-coated carbide for cast iron machining
• Double-sided chipbreaker for flexible use
• Square SNMG insert, 12 mm size
• 1.2 mm corner radius for robust cutting edge

High-efficiency cast-iron turning with reliable coating

The SNMG120412 T515 is designed around a CVD-coated carbide grade optimised for the economical machining of cast iron. The CVD layer improves resistance to abrasive wear and helps maintain a sharp edge under interrupted cuts, which results in longer tool life and fewer insert changes. For production environments, this translates into a measurable reduction in downtime and more consistent component tolerances, since the coating supports sustained cutting performance under typical turning forces.

Stable edge geometry that cuts downtime and inventory

A 1.2 mm corner radius combined with a double-sided chipbreaker delivers a balance between edge strength and chip control, making the insert suitable for semi-finish and finish operations where robustness is required. The square shape and 12 mm size provide four usable edges per insert, improving stock efficiency. The 0° relief angle and a cylindrical hole ensure secure clamping in compatible holders; the insert’s 4.76 mm thickness contributes to rigidity and resistance against vibration during heavier cuts.

Compatible system integration and selection guidance

This ISO insert is part of the standard system comprising an ISO indexable insert, a matching external holder or boring bar, plus shim and clamp set with replacement screws. Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness. Select the chipbreaker and grade according to material ductility, cut interruptions and desired cutting speed to exploit the Tungaloy quality in recurring production tasks. Proper selection ensures repeatable surface finish and consistent process security across batches.

FAQ

What materials is this insert suitable for?
The SNMG120412 T515 Tungaloy indexable insert is optimised for cast iron machining due to its CVD-coated carbide grade designed for abrasive resistance and stable chip formation.

Can the insert be clamped in standard SNMG holders?
Yes, the SNMG120412 follows ISO dimensions for SNMG inserts; secure clamping depends on matching form, tolerance class, relief angle and attachment method of the holder.

How many cutting edges are available per insert?
Being a square, double-sided SNMG insert offers up to four usable cutting edges, which supports economical stocking and reduces replacement frequency.

What cutting applications benefit most from this grade?
The T515 grade is aimed at economical machining of cast iron in both external and internal turning where wear resistance and reliable chip control are priorities.

Does the corner radius affect feed and surface finish?
The 1.2 mm corner radius favours edge strength and stability for moderate feeds; it supports improved tool life and a consistent surface finish compared with finer radii.
