TPMT 110204 NS9530 Tungaloy turning insert — TPMT110204 finishing cermet for turning

A TPMT110204 NS9530 indexable insert designed for finishing operations on steel, offering a sharp cutting edge and stable performance for continuous cuts and small depths of cut.

• Finishing cermet grade NS9530 for steel
• Sharp edge for low cutting forces
• Triangle insert, 11 mm size, 0.4 mm radius
• Cylindrical hole with 40°–60° countersink

Delivering superior surface finish with reduced cutting forces

The uncoated cermet grade NS9530 is engineered for finishing, producing a consistently fine surface while keeping cutting forces low. In practical terms, this means fewer passes to achieve target tolerances and a reduced tendency for built-up edge when machining steel under continuous cutting conditions. The combination of a finely honed cutting edge and small nose radius results in reliable dimensional control and an improved cosmetic finish, which lowers downstream grinding or polishing requirements and shortens cycle times.

Assured fit and predictable clamping in ISO tool systems

Compatibility with the toolholder is determined by form, relief angle, tolerance class, fastening, size and thickness. The ISO designation and triangular geometry ensure the insert matches standard TPMT holders; the 11° relief angle and 60° included angle provide clear reference points for clamping and tool setup. The insert’s 11 mm inscribed circle, 2.38 mm thickness and cylindrical hole with 40°–60° countersink simplify replacement and reduce set-up variation, contributing to steady process repeatability on the shop floor.

Why an uncoated cermet benefits finishing operations

Cermet combines ceramic hardness with metal toughness to deliver a cutting edge that resists deformation at elevated temperatures typical of finishing passes. As an uncoated cermet, this grade prioritises sharpness and surface integrity rather than heavy-duty abrasion resistance, which is ideal for light feeds and shallow depths of cut. The result is improved surface roughness with minimal burr formation, less need for rework and consistent part quality—advantages that are particularly valuable in long-run production where reproducibility matters.

Stable chip control and efficient tool handling for productivity

The insert features a single-sided chipbreaker that promotes stable chip formation during finishing cuts, aiding evacuations and reducing the risk of chip re-cutting. As an ISO-format insert, it fits into established systems comprising an external holder or boring bar, support shim/clamp sets and replacement screws, allowing quick swaps and predictable torque settings. This modular approach reduces machine downtime and facilitates efficient tool inventory management, supporting higher machine uptime and lower per-part costs.

FAQ

What material is this insert optimised for?
The TPMT110204 NS9530 insert is optimised for finishing steel, delivering a sharp cutting edge and improved surface quality in continuous cuts.

Can the insert be used in standard ISO holders?
Yes, the ISO designation and triangular form ensure compatibility with matching TPMT-design toolholders, subject to matching form, clearance angle, tolerance class, fastening and thickness.

What cutting tasks suit an uncoated cermet grade?
Uncoated cermet grades such as NS9530 are best for finishing operations that require low cutting forces, fine surface finish and continuous cutting with small depths of cut.

How does the hole and countersink affect clamping?
The cylindrical hole with a 40°–60° single-sided countersink provides a stable seating and repeatable clamping position, supporting consistent tool offsets and ease of replacement.

Is the TPMT110204 suitable for interrupted cuts?
The NS9530 finishing grade is optimised for continuous cuts and small depths of cut; for heavily interrupted cutting, a different grade with greater toughness is typically recommended.
