TNMG160404 160404 T9225 turning insert by Tungaloy — robust CVD-coated carbide for steel turning

a TNMG160404 T9225 indexable insert designed for external and internal turning in medium to heavy steel applications

• CVD-coated carbide grade T9225
• Triangular TNMG form, 60° cutting edge
• 0.4 mm nose radius for versatile profiles
• Double-sided chipbreaker for consistent chips

Consistent cutting performance for medium to heavy turning

The combination of CVD-coated surface treatment and a tough carbide substrate delivers a durable cutting edge suited to variable engagement and slightly interrupted cuts. The T9225 grade is formulated for steel machining where a balance of wear resistance and toughness is required, so tool life remains predictable under mixed conditions. This translates into fewer insert changes and a steadier production flow, supporting efficiency goals on batch and continuous turning operations.

Guaranteed fit and repeatable accuracy with ISO form

Manufactured to the ISO TNMG form, the insert ensures compatibility with standard external holders and boring bars when the form, clearance angle, tolerance class, fastening method, size and thickness match. The insert’s 60° included angle and 0° relief are critical dimensions to check against the clamping system; correct pairing avoids misalignment and enables repeatable geometries. Specifying the appropriate holder and shim will maintain concentricity and surface finish, reducing rework and scrap.

Better chip control and longer edge life reduce downtime

A double-sided chipbreaker supports reliable chip formation across a range of feeds and depths, improving evacuation and reducing the risk of built-up edge. Being indexable on both sides allows economical use of the cutting geometry, extending effective life per insert. Stable chip control improves surface quality and lowers the frequency of machine stops for manual clearing, which contributes directly to productivity and lower total machining cost.

Practical application notes and system components

The triangular geometry with a central cylindrical hole provides secure clamping with common TNMG holders; the 0.4 mm nose radius suits finishing passes and moderate profile features without compromising strength. Typical system setup comprises an ISO turning insert, a matching external holder or boring bar, a locating pad or clamping set and replacement screws. For interrupted cuts or less rigid set-ups, the toughness of the T9225 grade helps absorb shock while maintaining a reliable edge.

FAQ

What materials is this insert best suited to machine? The TNMG160404 T9225 insert is optimised for steel machining and offers a broad coverage for medium to heavy turning tasks thanks to its CVD-coated T9225 carbide composition.

How does the 0.4 mm nose radius affect component finish? A 0.4 mm nose radius provides a good compromise between profile accuracy and edge strength, enabling fine surface finishes while still resisting wear in typical turning operations.

Is the insert reversible and how many cutting edges are available? This TNMG form is double-sided with a chipbreaker on both faces, allowing multiple indexing positions and extending the usable life of each insert.

Which holder features must match to ensure correct clamping? Compatibility requires matching form, clearance angle, tolerance class, fastening method, size and thickness — check the holder accepts TNMG inserts with a 60° included angle and a cylindrical centre hole.

Can this insert handle interrupted cuts? The T9225 grade offers enhanced toughness suitable for slightly interrupted cuts, making the insert a reliable choice where varying engagement occurs.
