TNMG220412 T9215 — triangular indexable turning insert, CVD-coated carbide, 60° (Tungaloy)

TNMG220412 T9215 is a triangular ISO indexable insert designed for external and internal turning in medium steel, combining a robust geometry with a high-wear CVD coating for productive, continuous to lightly interrupted cuts.

• CVD-coated carbide T9215
• Optimised for medium steel machining
• Triangle form, 22 mm, 4.76 mm thick
• Double-sided chipbreaker, cylindrical hole

Boosted productivity for medium-steel turning

The triangular indexable insert delivers a balance of wear resistance and fracture toughness, making it suitable for batch and continuous production in steel components. The T9215 grade employs a CVD-coated carbide substrate that resists abrasive wear while maintaining edge stability under typical turning loads; this leads to longer tool life and fewer interruptions for insert changes. For operations where repeatable surface finish and consistent cycle times matter, the combination of geometry and coating supports higher cutting speeds and reliable machining performance.

Geometry and coating that aid process reliability

A triangle form with a 60° approach angle and a 1.2 mm corner radius provides a robust cutting edge for both roughing and finishing passes. The insert’s 0° clearance and 4.76 mm thickness contribute to secure clamping and reduce the risk of chipping in interrupted cuts. The double-sided chipbreaker geometry is engineered to control chips effectively on medium steel, improving evacuation and preventing re-cutting. These design choices translate into predictable forces, reduced vibration and a more consistent surface quality on each workpiece.

Simple compatibility and secure mounting

The insert conforms to ISO dimensions for easy pairing with standard holders; compatibility depends on form, clearance angle, tolerance class, fastening method, size and thickness. The central cylindrical hole facilitates secure fixation with a screw and clamping assembly, while the standard ISO designation supports straightforward procurement and inventory control in production environments. When paired with the correct holder and clamping set, the insert forms part of a reliable system that reduces setup time and simplifies tool management.

Application guidance for best results

Intended primarily for medium steel turning, this insert performs well in continuous to slightly interrupted cuts; select the chipbreaker and grade according to the specific workpiece material and machining stability. Use moderate feeds and increase cutting speed within recommended data for the CVD-coated carbide grade to exploit its wear resistance without compromising edge life. For less stable set-ups or heavy interruptions, choose a more robust holder and consider reduced depth of cut to maintain tool security and surface integrity.

FAQ

What materials is this insert intended for?
The Tungaloy TNMG220412 T9215 insert is optimised for medium steel machining; the T9215 CVD-coated carbide grade combines wear resistance with fracture toughness suitable for such applications.

How does the chipbreaker design affect performance?
The double-sided chipbreaker on the TNMG220412 helps control chip formation and evacuation during turning, improving surface finish and reducing the risk of chip entanglement in medium-steel operations.

Which holders are compatible with this ISO insert?
Compatibility requires an ISO holder that matches the TNMG220412 form, clearance angle, tolerance class, fastening method, size and thickness; secure clamping via the cylindrical hole is necessary for stable cutting.

Can this insert handle interrupted cuts?
The insert and its CVD-coated carbide grade are suitable for continuous to lightly interrupted cuts; for heavy interruptions, assessment of holder rigidity and cutting parameters is recommended.

What is the significance of the 1.2 mm corner radius?
A 1.2 mm corner radius provides a balance between edge strength and surface finish, offering robustness in roughing while still permitting acceptable finishing quality in many turning tasks.
