TNMG 160408 GH330 Turning insert by Tungaloy – triangular, 60° cutting angle, carbide grade GH330

A TNMG160408 GH330 Tungaloy turning insert designed for general external and internal turning applications, offering a balance of wear resistance and edge stability for reliable production results.

• ISO triangular insert, 60° cutting angle
• GH330 grade for wear resistance
• 0.8 mm corner radius for fine finishes
• Cylindrical hole for secure clamping

Predictable performance from a wear-resistant grade

The GH330 grade is a Tungaloy carbide formulation optimised for turning: it combines wear resistance and edge toughness to maintain cutting-edge stability over longer tool life. This performance profile reduces unexpected downtime and contributes to a more predictable process window in serial production. Where frequent insert changes are costly, the GH330 composition helps lower overall tooling expenditure by extending the effective life of each indexable edge.

Clear compatibility and secure clamping for simple tool selection

As an ISO-standard triangular insert, compatibility with toolholders depends on geometric fit: form, relief angle, tolerance class, fastening method, size and thickness determine correct pairing. This insert is a triangular type with a 60° included angle, a corner radius of 0.8 mm, and a thickness of 4.76 mm. The centre features a cylindrical hole for secure clamping in compatible external holders or toolposts. Understanding these dimensions ensures the insert seats correctly, transmits cutting forces safely and achieves the expected surface finish and tool life.

Practical application advice for machining and chip control

The insert is double-sided with a dedicated chipbreaker on both faces, allowing economical use of both cutting edges and consistent chip formation on a variety of workpieces. It is intended for turning and is suitable when a balance of surface quality and productivity is required. Select the chipbreaker style and grade based on workpiece material, cutting mode and machine stability; a robust grade like GH330 is well suited to mixed production runs where hard-wearing performance and reliable edge behaviour are priorities. For less experienced operators, matching the insert to a correctly specified holder and following recommended feed and speed guidelines from tooling documentation will reduce risk and improve first-time-right parts.

FAQ

What materials is this insert suitable for?
The TNMG160408 GH330 Tungaloy insert is formulated for a wide range of turning tasks; the GH330 grade provides good wear resistance and edge stability across steels and mixed material batches.

How does the cylindrical hole affect mounting?
A cylindrical hole ensures consistent seating and secure clamping in compatible toolholders; the TNMG160408 geometry is designed to mate with ISO-standard clamping systems for stable cutting.

Can both sides of the insert be used?
Yes, the insert is double-sided with chipbreakers on both faces, allowing indexing to a fresh edge and maximising the number of usable cutting edges.

What does the 0° relief angle mean in practice?
A 0° relief angle indicates the insert’s specified clearance geometry; combined with the 60° triangular shape and correct holder, it helps maintain cutting edge position for accurate turning results.

Is the corner radius suitable for fine surface finishes?
The 0.8 mm corner radius on the TNMG160408 insert balances edge strength and the ability to achieve fine surface finishes when paired with appropriate feeds and speeds.
