SNMG 120404 T5105 indexable turning insert by Tungaloy — for turning applications

A SNMG120404 T5105 indexable insert designed for high-speed external and internal turning of cast iron under stable machining conditions.

• CVD-coated carbide grade T5105
• Square plate, 12 mm size
• 0.4 mm corner radius for finishing
• Double-sided chipbreaker with cylindrical hole

Optimised high-speed cutting for cast iron

The combination of a T5105 grade and CVD-coated carbide substrate is engineered for extended edge life during high-speed machining of cast iron. The wear-resistant coating reduces flank wear and maintains cutting-edge geometry, which leads to fewer indexings and longer unattended runs. As a consequence, cycle times are reduced and tool-change frequency drops, supporting predictable throughput in serial production.

ISO compatibility for reliable holder integration

The insert follows ISO specifications; compatibility with toolholders depends on form, relief angle, tolerance class, fastening method, size and thickness. This standardised geometry simplifies tool inventory and allows quick swapping between matched holders or boring bars, reducing setup time. The square plate with a cylindrical hole ensures secure clamping and repeatable positioning, which supports consistent part quality across shifts.

Coating and substrate that support consistent performance

The CVD-coated surface atop a hard carbide substrate provides high abrasion resistance and thermal stability during interrupted cuts and elevated cutting speeds. CVD coatings form a thin, adherent layer that resists abrasive wear and helps control built-up edge formation when machining abrasive or nodular cast irons. The result is a more uniform tool life and steadier surface finish over long production runs.

Design details that sustain productivity and surface quality

A 0.4 mm corner radius is well suited for finishing and light semi-finishing passes, balancing edge strength with surface definition. The double-sided chipbreaker increases indexable life per insert by offering two usable cutting edges and improved chip control, while the square 12 mm plate format provides multiple indexing positions. Together, these details reduce downtime for index changes and help maintain consistent part tolerances in turning operations.

FAQ

Which materials is this insert best suited for?
The SNMG120404 T5105 insert is optimised for high-speed machining of cast iron; the T5105 grade and coating resist abrasive wear typical for many cast-iron alloys.

What does the designation T5105 indicate?
T5105 denotes a wear-resistant, CVD-coated carbide grade designed for stable, high-speed cutting performance and extended edge life in cast-iron applications.

Is the insert indexable and reversible?
Yes — the square plate offers multiple indexing positions and the double-sided chipbreaker provides two usable cutting edges per indexable side, improving overall tool economy.

How is holder compatibility determined?
Compatibility requires matching the insert form, relief angle, tolerance class, fastening method, size and thickness to the chosen holder; ensure the holder accepts a 12 mm square insert with a cylindrical hole and 4.76 mm thickness.

Is this insert suitable for finishing operations?
With a 0.4 mm corner radius and the T5105 wear properties, the insert is well suited to finishing and light semi-finishing passes, delivering consistent surface quality.
