TNMG 160412 NS9530 TNMG turning insert for finishing — Tungaloy

A TNMG 160412 NS9530 indexable turning insert engineered for finishing steel, offering a sharp cutting edge and optimised chip control in continuous cutting operations

• NS9530 uncoated cermet for high surface finish
• 60° triangular insert with 1.2 mm corner radius
• Double-sided with cylindrical hole for secure clamping
• Designed for finishing steel with low cutting forces

Precision finishing with a low-force cutting edge

The NS9530 grade is an uncoated cermet optimised for finish turning of steel, delivering a consistently high surface finish and reduced cutting forces compared with conventional grades. As a finishing grade, it is intended for continuous cuts and small depths of cut, where the combination of a sharp cutting edge and the material properties of cermet produce fine surface quality and low built-up edge. For production environments that require repeatable part quality, this geometry helps to maintain tight tolerances with predictable performance.

ISO compatibility and secure clamping for reliable integration

The insert follows the ISO TNMG160412 designation, which defines the triangular 60° geometry and size class; compatibility with a holder is determined by form, relief angle, tolerance class, fastening, size and thickness. The insert’s 0° relief angle, 4.76 mm plate thickness and cylindrical hole require a matching clamping system—either an indexed pocket or a screw-down set-up with the appropriate shim and screw. Choosing the correct external holder or boring bar ensures stable seating, repeatable positioning and safe torque transmission during turning operations.

Predictable chip control and economical indexing

Equipped with a double-sided chipbreaker, the insert provides improved chip control during finishing passes and extends usable life through indexing. The 1.2 mm corner radius supports edge strength without compromising the fine surface quality expected from a finishing insert. Because the grade is uncoated, it offers a consistent cutting geometry and can be preferable where coating-related adhesion or thermal effects are a concern. Fewer unexpected variances in edge geometry mean less downtime and more predictable tool-change intervals.

Simple selection and system overview for workshop use

The machining system for this insert typically comprises the ISO indexable turning insert, a compatible external holder or boring bar, a supporting shim/clamping kit and replacement screws. For practical selection: match the insert’s TNMG shape, size 16, thickness 4.76 mm and hole style to the holder’s pocket; select the NS9530 grade specifically for finish-turning of steel with small feeds and depths. If uncertainty remains about holder compatibility or the right cutting parameters, refer to the holder manufacturer’s pocket specifications or consult a tooling specialist to avoid mismatched geometry.

FAQ

Is this insert suitable for roughing operations?
The NS9530 grade and the TNMG160412 geometry are designed as a finishing grade for steel; it is not optimised for heavy roughing where larger depths of cut and interrupted cuts are required.

How does the TNMG 160412 secure to the holder?
The insert features a cylindrical hole and requires a matching clamping system—shim and screw or an ISO-compatible pocket—so that the seating, tolerance class and fastening method correspond to the holder design.

What benefits does the uncoated cermet grade provide?
The NS9530 uncoated cermet offers a sharp cutting edge and stable performance in continuous finish cutting, giving consistent surface finish and lower cutting forces compared with some coated grades.

Can the insert be indexed to use the second side?
Yes; the double-sided design allows indexing to the opposite cutting edge, effectively doubling the number of available edges and improving overall tool economy.

Which holder characteristics must be checked for compatibility?
Verify holder pocket form, relief angle match (0° relief), tolerance class, fastening method, size (16) and plate thickness (4.76 mm) to ensure correct fit and repeatable positioning.
