TNMA 220412 T5105 – ISO triangular turning insert for turning, Tungaloy

The TNMA220412 T5105 is an ISO triangular turning insert designed for high-speed machining of cast iron under stable cutting conditions.

• CVD-coated carbide for high-speed turning
• ISO TNMA 220412 triangular form
• 1.2 mm corner radius for precise profiling
• Compatibility with cylindrical-hole clamping

Increased productivity through wear-resistant coating

The combination of a CVD-coated carbide substrate and the high-performance T5105 grade enables extended tool life during demanding turning operations. Designed specifically for stable, high-speed machining of cast iron, this grade offers improved wear resistance which translates into fewer tool changes and steadier production cycles. For applications where surface finish and repeatability matter, the coating supports consistent cutting-edge behaviour and reduces flank wear, thereby increasing overall process efficiency.

Reliable fit and secure clamping for predictable setup

As an ISO-standardised insert, the triangular geometry and the included cylindrical hole ensure compatibility with a wide range of holders when the form, clearance angle and tolerance class match. The listed 0° clearance angle, 22 mm size and 4.76 mm thickness result in a robust clamping interface that helps to reduce vibrations under stable conditions. This predictable fit simplifies set-up validation and supports repeatable mounting, improving first-pass accuracy and reducing downtime associated with re-clamping.

Application guidance for process optimisation and cost-efficiency

Intended primarily for external and internal turning of cast iron, the insert performs best when matched with a suitable chip former and stable machining parameters; note that this variant is supplied without a chipbreaker, so chip control must be managed by selecting an appropriate holder or cutting strategy. The 1.2 mm corner radius and the 60° included angle provide a balance between edge strength and form detail, making the grade suitable for medium to fine profiling work. When combined with the right holder and cutting data, this configuration can deliver lower tool consumption and improved productivity across continuous production runs.

FAQ

Which materials is this insert optimised for?
The TNMA220412 T5105 insert is optimised for machining cast iron, using the CVD-coated carbide to provide wear resistance in high-speed turning.

Is a specific holder required for secure clamping?
Compatibility depends on holder form, clearance angle, tolerance class, clamping method and plate size; the cylindrical-hole design suits holders that accept ISO TNMA triangular inserts.

Does this insert include a chipbreaker?
This variant is supplied without a chipbreaker, so chip control should be achieved through an appropriate holder design or adjusted cutting parameters.
