TCMT 110308 NS9530 Tungaloy indexable turning insert — for turning, 60° triangular

TCMT 110308 NS9530 is an ISO‑standard triangular indexable insert designed for finishing operations in turning, offering a low cutting force geometry and a fine surface‑quality focus.

• ISO‑standard triangular insert TCMT 110308
• Uncoated cermet grade NS9530 for fine finishing
• 0.8 mm corner radius for precise profiles
• Cylindrical hole with one‑side 40°–60° countersink

Consistent finishing with a specialist cermet grade

The insert is manufactured with an uncoated cermet cutting grade (NS9530) that delivers a sharp cutting edge and low cutting forces, making it particularly suited to continuous cuts and small depths of cut. This geometry reduces chatter and supports a consistently high surface finish on steel workpieces. For shops prioritising productivity in finishing passes, the combination of the cermet grade and the insert geometry provides an efficient, repeatable cutting action that shortens rework and improves process stability.

ISO compatibility and secure clamping for dependable results

As an ISO‑standard indexable insert, compatibility with the toolholder is determined by shape, relief (7°), tolerance class, fastening method, size and thickness. Correct seating on a matched external holder or boring bar, combined with the appropriate shim and clamping set plus replacement screws, ensures repeatable positioning and tool life. The standardised form simplifies tool inventory management and allows rapid changeover between inserts and holders, supporting stable production workflows.

Geometry optimised for precision turning

The triangular plate with a 60° included angle and a 0.8 mm corner radius is designed for precise profile work and fine detail on turned components. With a plate size of 11 mm and a plate thickness of 3.18 mm, the insert offers mechanical stability while remaining suitable for finishing passes. The cylindrical hole with one‑side countersink (40°–60°) ensures secure mounting and correct clamping alignment, reducing the risk of movement during high‑precision operations.

Practical use cases and selection guidance

Ideal for external and internal turning where surface quality is a priority, this insert is best paired with a single‑sided chipbreaker selected to match the workpiece material and cut conditions. For steel finishing operations with continuous chip formation, the NS9530 grade reduces cutting forces and delivers a smoother finish. When choosing feed and speed, favour conservative parameters for the initial setup and adjust to the machine, workholding and stability; the insert’s design supports fine tuning for best results.

FAQ

What materials is this insert suitable for?
The TCMT 110308 NS9530 insert is formulated as a finishing grade for steel; the uncoated cermet NS9530 performs particularly well in continuous cuts on steel workpieces.

How is the insert secured in the holder?
Mounting relies on the cylindrical hole with a one‑side countersink (40°–60°); correct clamping with the matching shim and screws ensures stable, repeatable seating of the TCMT 110308 NS9530 insert.

Can this insert be used for roughing operations?
This grade and geometry are optimised for finishing; for heavy roughing, a different insert geometry and chipbreaker suited to higher depths of cut is recommended rather than the NS9530 finishing grade.

What advantages does the 0.8 mm corner radius offer?
The 0.8 mm corner radius helps achieve precise profiles and improved surface finish while maintaining adequate edge strength for small feed finishing passes with minimal burr formation.

Which holders are compatible with this ISO insert?
Any toolholder or boring bar designed for ISO TCMT 110308 inserts and matching the form, relief angle (7°), size and thickness will be compatible; confirm tolerance class and fastening style before mounting.
