CNMG090408 T9215 turning insert — Tungaloy — ISO rhombic 80° geometry for turning

CNMG090408 T9215 Tungaloy turning insert designed for medium-steel turning with a double-sided chipbreaker and cylindrical hole for secure clamping

• ISO CNMG090408 format, rhombic 80° geometry
• CVD-coated carbide T9215 for medium steel
• Double-sided chipbreaker, with cylindrical hole
• 0° clearance angle, 0.8 mm corner radius

High productivity and predictable tool life for medium-steel turning

The combination of CVD-coated carbide and the T9215 grade offers a balance between wear resistance and fracture toughness that supports high productivity in continuous to lightly interrupted cuts. The rhombic 80° geometry increases the effective cutting edge strength, while the 0.8 mm corner radius reduces the risk of edge chipping when machining interrupted sections. These attributes translate into longer intervals between indexings and more stable cycle times in serial turning operations.

Robust edge control and reliable chip formation

A double-sided chipbreaker matched to the grade promotes controlled chip formation across typical turning feeds used on medium steels. The insert’s 4.76 mm thickness and the presence of a cylindrical hole for positive locating minimise vibration in the tool assembly and enhance repeatability. The 0° clearance angle is advantageous where a neutral rake and stable contact with the workpiece are required, contributing to consistent surface finish and reduced process variation.

Seamless integration with ISO tooling systems for rapid changeovers

The ISO standardisation of the insert simplifies toolholder selection and machine setup: compatibility is determined by form, clearance, tolerance class, fastening, size and thickness. The CNMG090408 format fits a wide range of CNMG holders used in modern lathes, allowing fast replacement and minimal downtime during tool change. Clear labelling and standard dimensions support inventory management and ease of procurement for production environments.

Practical guidance for machining and application security

For the best results in medium-steel turning, combine the T9215 grade with a chipbreaker that suits the chosen feed and depth of cut; the insert excels in applications where a balance of wear resistance and toughness is required. Selection of the correct holder and stable workpiece clamping further enhances the advantages of the insert, reducing chatter and improving tool life. For process validation or parameter tuning, Metav Werkzeuge’s technical team can provide application-focused advice to match the insert’s properties to the machining task.

FAQ

What materials is this insert intended for?
The Tungaloy CNMG090408 T9215 insert is specified for medium-steel applications; the T9215 grade combines wear resistance and toughness suitable for a broad range of steel alloys.

Can the insert be used for interrupted cuts?
Yes, the CVD-coated T9215 grade provides fracture resistance appropriate for continuous to light interrupted cutting conditions in turning operations.

Which toolholders are compatible with this insert?
Compatibility depends on holder form, clearance, tolerance class, fastening and thickness; the ISO CNMG090408 format is suitable for standard CNMG holders when those dimensions match.

How does the 0.8 mm corner radius affect performance?
A 0.8 mm corner radius increases edge strength and improves resistance to chipping, offering a compromise between a robust edge and achievable surface finish.

Is the chipbreaker design reversible or single-use?
The insert is double-sided with a chipbreaker on each cutting edge, allowing indexing to the second edge and extending usable tool life.
