TNMG160412 T9225 triangular indexable insert for turning — Tungaloy

The TNMG160412 T9225 is an ISO-standard triangular indexable insert designed for robust external and internal turning in medium to heavy steel machining, offering reliable edge stability and simple replacement.

• Robust CVD-coated carbide grade T9225
• Universal for medium to heavy steel turning
• Triangular insert, 60° cutting angle
• Double-sided chipbreaker, cylindrical hole

Stable cutting performance for varying engagement conditions

The TNMG160412 indexable insert pairs a CVD-coated carbide substrate with the T9225 grade to provide a balanced mix of hardness and toughness suitable for interrupted cuts and fluctuating engagement depths. The combination of coating and substrate yields improved edge stability, lowering the frequency of tool changes and supporting longer continuous runs. This results in a measurable increase in process reliability for shops machining medium to heavy steel, where consistent performance under varying loads is essential.

Efficient chip control and reduced rework

A key advantage is the double-sided chipbreaker, designed to control swarf formation under typical turning feeds for the target materials. Controlled chip flow reduces risk of surface damage and keeps the toolpath clear, which shortens cycle times and reduces manual intervention. The 60° cutting angle and corner radius 1.2 mm also contribute to a favourable balance between cutting forces and surface finish, so fewer passes are needed to meet dimensional and visual tolerances.

Practical handling, quick indexing and secure clamping

The triangular geometry and cylindrical hole allow straightforward indexing and reliable clamping in ISO-compatible holders; the insert is double-sided, offering two usable edges per face and extending effective tool life. The 4.76 mm thickness and defined tolerance classes ensure repeatable seating in standard insert pockets, simplifying inventory management and reducing setup variability across multiple machines and operators.

Application guidance and compatibility overview

Intended for conventional turning operations, this insert suits both external and internal features when paired with the correct holder and mounting hardware. Selection of the T9225 sort is recommended where moderate to heavy cuts and occasional interruptions occur; choose a matching holder geometry, clearance angle and tolerance class to ensure firm contact and optimal cutting geometry. The insert’s universal character reduces the need for multiple specialised grades in mixed-production environments.

FAQ

What materials is this insert suitable for?
The TNMG160412 T9225 insert is formulated for medium to heavy steel machining and performs well under interrupted cuts where increased toughness is needed.

How does the T9225 grade affect tool life?
The T9225 grade combines wear resistance and toughness; for the TNMG160412 this means longer edge life in variable cutting conditions compared with uncoated or softer grades.

Is the insert compatible with standard ISO holders?
Yes, the insert follows ISO geometry; compatibility depends on holder form, clearance angle and tolerance class, and the TNMG160412 seats securely in standard ISO pockets.

How many cutting edges are available per insert?
Being double-sided and triangular, the insert provides multiple indexable edges; the exact count depends on orientation but offers economical edge utilisation.

Does the CVD coating improve surface finish?
The CVD-coated surface on the TNMG160412 helps maintain edge sharpness and heat resistance, contributing to consistent surface quality over longer runs.
