TNMG 160408 T5115 indexable turning insert for turning, CVD-coated carbide (Tungaloy)

TNMG 160408 T5115 is an ISO-format triangular indexable insert designed for external and internal turning operations, offering a universal grade optimised for cast iron machining.

• CVD-coated carbide grade T5115
• 60° triangular insert, 16 mm size
• 0.8 mm corner radius
• Double-sided chipbreaker, cylindrical hole

Consistent chip control for stable production

The combination of a double-sided chipbreaker and the CVD-coated carbide substrate provides predictable chip formation during continuous turning. This results in reduced interruptions for chip management and fewer tool changes, which directly improves cycle times. For production planners, the technical design reduces the need for complex parameter tuning: the insert's chipformer suits typical cast iron cutting conditions and maintains surface quality while limiting built-up edge.

Robust edge stability for cast iron turning

The T5115 grade, a CVD-coated carbide, balances wear resistance and edge toughness to withstand the abrasive nature of cast iron. The slightly rounded 0.8 mm corner radius provides stronger edge support than sharp corners, helping to avoid chipping on interrupted cuts. In practice this means longer tool life per index and a more consistent surface finish on parts where repeatability matters.

Versatile geometry paired with secure clamping

The 60° triangular geometry and the presence of a cylindrical hole ensure mechanical compatibility with a wide range of ISO holders. The insert thickness of 4.76 mm and the standardised form make selection and replacement straightforward; compatibility is determined by form, relief angle, tolerance class, fastening method, size and thickness. Using standardised ISO insert systems simplifies tooling logistics and enables fast, secure clamping in both turning holders and boring bars.

Practical explanation of key terms

An indexable insert is a replaceable cutting element that can be rotated or flipped to use multiple cutting edges; this reduces the frequency of tool replacement compared with brazed tools. CVD coating (chemical vapour deposition) adds a hard, wear-resistant layer to the carbide substrate, improving resistance to abrasion at elevated temperatures. The result for workshop teams is fewer interventions, predictable tool life and a clear maintenance schedule.

FAQ

What materials is this insert suitable for?
The TNMG 160408 T5115 insert is a universal grade optimised for cast iron; the T5115 CVD-coated carbide substrate also performs well under standard turning conditions where a balance of wear resistance and edge stability is required.

How does the 0.8 mm corner radius affect machining?
A 0.8 mm corner radius increases edge strength and reduces the risk of chipping on interrupted cuts, producing a more robust cutting edge and improving tool life compared with very fine radii.

Can this insert be used in internal turning and boring bars?
Yes, the ISO-format TNMG 160408 insert with a cylindrical hole and standard thickness is compatible with appropriately sized external holders and boring bars for internal turning, subject to correct holder selection.

How many cutting edges are available per insert?
The triangular, double-sided design allows multiple effective cutting edges per insert; the exact number depends on the indexable system orientation, but the geometry supports economical edge utilisation.

Which Tungaloy product code identifies this insert?
This item is listed as TNMG 160408 T5115 with manufacturer article number 6850287 and manufacturer SKU TUN6850287 for ordering and inventory purposes.
