TNMG220404 GH330 Tungaloy indexable turning insert — 60° triangular, carbide grade GH330

The TNMG220404 GH330 Tungaloy is an ISO‑standard indexable turning insert intended for external and internal turning, offering robust cutting edge stability and broad applicability in conventional turning operations.

• ISO‑standard TNMG geometry, 60° triangular
• Carbide grade GH330 for wear resistance
• Double‑sided chipbreaker for economical indexing
• Cylindrical hole and 4.76 mm plate thickness

Optimised for consistent turning performance

The TNMG series is designed to deliver consistent cutting results across a variety of turning tasks. The combination of a carbide substrate and the GH330 grade extends tool life where moderate wear resistance and good edge stability are required. For production environments that prioritise uptime and repeatability, the insert’s geometry and grade work together to reduce unexpected tool changes and maintain surface finish standards. Selecting the correct chipbreaker and grade for the workpiece material optimises chip control and minimises rework, supporting a more economical machining process.

Precise geometry for reliable holder compatibility

The insert code TNMG220404 denotes an ISO triangular insert with a 60° included angle and a 0.4 mm corner radius, engineered to fit ISO‑compatible holders when matched by form, relief angle, tolerance class, clamping method, size and thickness. The nominal inscribed circle of 22 mm and plate thickness of 4.76 mm ensure mechanical stability during cutting. The specified 0° relief angle and the presence of a cylindrical hole allow secure fastening in conventional clamping systems. These geometric attributes translate into predictable cutting forces and repeatable positioning, which is essential for precision turning operations and quick insert indexing.

Practical features that reduce machining costs

Built as a double‑sided insert, the TNMG220404 supports economical tool usage by providing multiple indexed edges before replacement, helping to lower tooling costs per part. The cylindrical hole facilitates secure clamping and straightforward replacement, while the triangular three‑edge form gives flexibility for different toolholder setups. With a carbide body and a Tungaloy grade engineered for a balance of toughness and wear resistance, the insert is suited for a wide range of turning tasks when paired with the appropriate chipbreaker. The net effect is improved productivity through longer effective cutting times and reduced setup interruptions.
