TNMG 160408 NS9530 turning insert — uncoated cermet, 0.8 mm nose radius (Tungaloy)

TNMG160408 NS9530 Tungaloy is an ISO‑standard indexable insert for precision turning, especially suited to fine finishing of steel components where low cutting forces and excellent surface quality are required.

• TNMG 160408 triangular insert, 60° angle
• Uncoated cermet grade NS9530
• 0.8 mm nose radius for fine finish
• Double-sided chipbreaker, with cylindrical hole

Precision finishing with reduced cutting forces

The uncoated cermet grade NS9530 is developed for finishing operations on steel, offering a sharp cutting edge and consistently low cutting forces. This behaviour supports improved surface quality and reduced workpiece distortion during light cuts. Where continuous cutting and small depths of cut are typical, the insert’s geometry delivers a predictable, repeatable finish that benefits batch production and single-part machining alike. The indexable design also simplifies re-indexing and reduces tool change times, aiding overall process efficiency.

Stable clamping and broad holder compatibility

Designed as an ISO indexable turning insert, the TNMG shape and dimensions conform to standard holder interfaces; compatibility is determined by form, clearance, tolerance class, fastening and thickness. The cylindrical hole and tolerance-compliant geometry ensure stable clamping in appropriate TNMG pockets, helping to maintain cutting edge position and minimise vibration. For workshops seeking predictable tool life and consistent component tolerances, the combination of standard form and robust seating improves process stability.

Geometry tailored for fine turning and surface quality

With a 60° included angle and a 0.8 mm nose radius, the insert balances edge strength and the ability to produce fine surface finishes. The double-sided chipbreaker supports controlled chip formation in finishing cuts, reducing the risk of surface blemishes and facilitating chip evacuation. Materials engineers will appreciate that the grade is optimised for continuous cutting on steel, making it suitable for components that demand tight surface specifications rather than heavy roughing.

Practical benefits for workshop productivity

Using a dedicated finishing grade such as NS9530 reduces secondary finishing steps and can shorten production cycles. The insert’s indexable nature means multiple usable edges per insert, which reduces tooling inventory and handling time. For job shops and production environments aiming to raise first-pass quality while keeping tool management straightforward, the insert provides a clear operational advantage through improved surface consistency and simplified re-indexing.

FAQ

What machining tasks suit this insert best? The TNMG160408 NS9530 Tungaloy insert is geared to finishing operations on steel where low cutting forces and high surface quality are priorities; it is intended for continuous cutting and small depths of cut.

Is the grade NS9530 suitable for interrupted cuts or roughing? NS9530 is a finishing grade optimised for continuous cuts; for interrupted cutting or heavy roughing, a tougher grade or a different chipbreaker geometry is recommended.

How does the hole and hole style affect clamping? The cylindrical hole provides standardised seating for compatible TNMG holders, contributing to secure clamping and repeatable positioning in ISO‑compliant tool systems.

Can this insert be used for internal turning as well as external? Yes, the insert’s ISO TNMG form and chipbreaker design make it suitable for both external and internal turning operations when mounted in appropriate holders.
