TNMG 160408 T5115 Wendeplatten - Tungaloy

Benefit from the combination of a CVD‑coated carbide grade T5115 and a 0.8 mm corner radius for consistent edge life and reliable performance in cast‑iron turning. Order the insert via Metav Werkzeuge or consult our advisers for compatibility and holder selection.

TNMG 160408 T5115 turning indexable insert (Tungaloy)

The TNMG160408 T5115 is a CVD‑coated carbide indexable insert engineered for external and internal turning, offering a balance of wear resistance and cutting‑edge stability for cast iron applications.

• CVD-coated carbide grade T5115
• 0.8 mm corner radius for repeatable edges
• ISO TNMG 160408 triangle insert, 60° geometry
• Double-sided with cylindrical hole, 4.76 mm thick

Optimised edge life and material compatibility

The insert uses a CVD‑coated carbide substrate in the T5115 grade, designed as a universal solution for machining cast iron with a well‑balanced compromise between abrasion resistance and edge stability. The 0.8 mm corner radius reduces the risk of premature chipping while still permitting productive depths of cut for finishing and light roughing. For shops seeking predictable wear behaviour, this composition supports longer intervals between indexings and consistent surface quality on cast‑iron components.

Straightforward integration with ISO toolholders

Built to the ISO TNMG 160408 standard, the triangular geometry with 60° main angle and a cylindrical hole ensures compatibility with a wide range of external holders and boring bars when the correct form, clearance and tolerance class are observed. The insert’s 4.76 mm thickness and 0° relief are relevant when checking holder pocket fit and screw clamp engagement; these dimensions contribute directly to axial and radial rigidity during turning, which in turn affects finish and repeatability.

Productivity through design and cost efficiency

Being double‑sided, the insert provides economical use of the cutting edges and reduces tooling changes, which is advantageous for medium‑ to high‑volume production. The triangular TNMG shape gives three indexable positions and, combined with the T5115 grade, helps to maintain a stable cutting edge under varying cutting conditions. Selecting the appropriate chipbreaker variant and operating parameters will maximise tool life and reduce cycle times while preserving component tolerances.

Practical selection and recommended use

For best results in turning operations, pair the insert with a holder that matches the pocket form and tolerance class; choose a chipbreaker suited to the required surface finish and stability. The specification supports both external and internal turning tasks on cast iron; for mixed workpiece materials, consider toolpath and cooling strategies to protect the cutting edge. If further clarification on holder compatibility or application‑specific recommendations is needed, technical guidance is available to ensure the right insert and chipbreaker combination is selected.

FAQ

What materials is this insert suitable for? The TNMG160408 T5115 Tungaloy indexable insert is specified primarily for cast iron machining and delivers a balanced combination of wear resistance and edge stability for that material.

How is the TNMG geometry beneficial in turning operations? The triangle TNMG 160408 shape provides three effective cutting positions; when combined with the 60° geometry and the 0.8 mm corner radius, the design supports versatile cutting strategies for finishing and light roughing.

Does the insert require a specific holder type? Compatibility is determined by holder form, free angle, tolerance class, clamp method, size and thickness; use holders compatible with ISO TNMG 160408 geometry and the cylindrical hole for correct mounting.

How many edges can be used before disposal? This double‑sided insert offers two usable edges per side, giving multiple indexings; proper selection of chipbreaker and cutting data will extend productive life.

What is the exact product reference for ordering? Order using the product reference TNMG160408 T5115 (SKU 6850292‑Tungaloy) to ensure the correct grade and geometry are supplied.
