TCMT TCMT16T308 16T308 NS9530 Tungaloy turning insert — uncoated cermet for finishing

A TCMT16T308 NS9530 ISO turning insert engineered for precision external and internal turning, offering a sharp edge and low cutting forces for superior surface quality

• ISO triangular insert geometry
• Uncoated cermet NS9530 for fine finishing
• Sharp cutting edge with low cutting forces
• Compatible with standard ISO turning holders

High-precision finishing with reduced cutting forces

The indexable insert is developed as a finishing grade: the NS9530 uncoated cermet provides a sharp cutting edge that reduces friction and delivers a fine surface finish on steels during continuous cuts and small depth-of-cut operations. Lower cutting forces translate into reduced tool deflection and more predictable part tolerances, which in turn cuts rework and improves overall process efficiency. This makes the insert particularly suitable where consistent surface quality and dimensional control are critical.

Clear geometry for predictable holder compatibility

Designed to ISO dimensions, the triangular shape with a 60° included angle ensures compatibility with many standard holders; a correct match depends on form, clearance angle, tolerance class, clamp type, size and thickness. Key geometry details include a 0.8 mm corner radius, 7° rake angle and a plate thickness of 3.97 mm, together with a cylindrical centre hole and a single-sided countersink (40°–60°). These exact values support predictable seating and clamping in properly specified toolholders, reducing set-up time and promoting repeatable tool life.

Application guidance and stable cutting performance

Intended primarily for turning, the insert performs well in both external and internal operations when paired with a suitable chipbreaker and cutting data adapted to material and machine rigidity. The single-sided chipbreaker and uncoated cermet grade favour finishing passes on steel where low cutting forces and excellent surface integrity are priorities. For mixed production runs, selecting a chipbreaker and feed suited to the component stability will maintain process security and extend productive periods between insert changes. As an ISO-standard indexable cutting insert from Tungaloy, the component supports efficient workflow and consistent part quality.

FAQ

What materials is this insert best suited for?
The TCMT16T308 NS9530 insert is specified as a finishing grade for steel; the uncoated NS9530 cermet delivers low cutting forces and excellent surface quality when machining steels.

Can this insert be used for both external and internal turning?
Yes, the insert is suitable for external and internal turning operations when paired with the appropriate holder and chipbreaker for the given stability and cutting conditions.

What does the 0.8 mm corner radius mean for part quality?
A 0.8 mm corner radius balances a fine surface finish with reasonable edge strength; it helps reduce marks on the workpiece while maintaining adequate resistance to edge chipping in finishing passes.

How does the insert’s 7° rake angle affect cutting?
The 7° rake provides a favourable shear geometry for low cutting forces and smooth chip formation, which supports consistent surface integrity during continuous cuts.

Is the TCMT16T308 compatible with standard ISO holders?
The insert conforms to ISO turning insert dimensions, but compatibility depends on matching the holder’s form, clearance angle, tolerance class, clamp and size to the insert’s specifications.
