SNMG 120408 T5105 – Tungaloy indexable insert for turning, CVD‑coated carbide

SNMG120408 T5105 is an ISO‑standard square insert engineered for stable, high‑speed turning of cast iron under robust clamping conditions.

• CVD‑coated carbide grade T5105 for long life
• Optimised for high‑speed turning of cast iron
• ISO SNMG 120408 geometry, 90° included angle
• 0.8 mm corner radius, double‑sided chipbreaker

Increase throughput with predictable tool life

The CVD‑coated cutting grade T5105 delivers a reliable combination of hardness and thermal stability, which supports sustained cutting at elevated speeds. This results in extended tool life and fewer index changes, so machining cycles become more consistent. As the grade is tailored for cast‑iron applications, the insert maintains a stable cutting edge in typical turning conditions, reducing the risk of unexpected edge breakage and downtime.

Clear compatibility for quick setup and consistency

Compatibility depends on insert form, relief angle, tolerance class, fastening, size and thickness; the square SNMG form and 0° relief angle match common external holders. The insert is supplied with a cylindrical hole, enabling secure clamping in standard SNMG toolholders with the usual shim/clamp arrangements. This system clarity simplifies tool selection and keeps changeover times short, especially in production environments using standardised holders.

Better surface quality and controlled chip formation

The double‑sided chipbreaker geometry supports consistent chip control during both roughing and finishing passes, which enhances surface integrity on grey and nodular cast iron. The 0.8 mm corner radius and 90° included angle offer a balance between edge strength and fine surface finish, helping to achieve the required tolerances with fewer passes. Operators will note improved repeatability and less rework when the insert is used within the recommended parameters.

Practical handling and cost efficiency

Being an ISO indexable insert, the component allows economical rotation to fresh cutting edges, effectively multiplying usable edges per insert and lowering per‑edge cost. The carbide substrate combined with CVD coating reduces flank wear and maintains dimensional accuracy over longer runs. For pragmatic productivity gains, pair the insert with a matching insert seat, clamp set and replacement screws as part of a controlled tooling system.

FAQ

What materials is this insert designed for?
The SNMG120408 T5105 insert is optimised for machining cast iron; the CVD‑coated T5105 grade provides wear resistance suited to high‑speed turning of grey and nodular cast iron.

How is the insert secured in the holder?
The insert features a cylindrical hole and standard SNMG geometry; it is clamped using a shim/clamp arrangement in compatible SNMG toolholders to ensure stable cutting.

How many usable cutting edges does this insert provide?
With its double‑sided chipbreaker the insert offers two indexed cutting edges per side, enabling multiple rotations to fresh edges before replacement.

What are the critical dimensions to check for compatibility?
Verify the 12 mm size, 4.76 mm thickness, 0.8 mm corner radius and 0° relief angle against the toolholder specifications to ensure correct seating and clamping.

Is this a good choice for finishing passes?
Yes; the 0.8 mm radius and 90° included angle balance edge strength and surface quality, making the insert suitable for both finishing and productive finishing operations when used with stable setups.
