DCMT11T308 NS9530 turning insert (uncoated cermet, 0.8 mm radius) — Tungaloy

A DCMT11T308 NS9530 indexable turning insert designed for finishing operations on steel, offering a sharp cutting edge and low cutting forces for smooth continuous cuts.

• ISO‑standard rhomboidal insert
• NS9530 uncoated cermet finishing grade
• Sharp edge for superior surface finish
• Compatible with holders requiring 7° relief

Reduced secondary operations through high-quality finishing

The uncoated NS9530 cermet is formulated as a finishing grade for steel, delivering low cutting forces and a high surface finish that often reduces the need for downstream grinding or polishing. Cermet substrates combine ceramic hardness with metallic toughness to keep the cutting edge sharp under continuous, light-depth passes; this makes the insert especially suitable where consistent surface quality is a production priority rather than heavy material removal.

Geometry tuned for stable clamping and repeatable results

Built to the ISO specification, the rhomboidal form provides predictable orientation and clamping across compatible toolholders. Key geometry values such as the 55° lead angle and 7° relief angle are matched to common external holders, while the 0.8 mm nose radius and 3.97 mm plate thickness support fine-profile turning. The central hole with a cylindrical bore and a single‑sided countersink (40°–60°) ensures secure fixation and straightforward replacement during batch production, maintaining repeatability across shifts.

Practical guidance for efficient process integration

The single‑sided chipbreaker and finishing nature of this insert favour continuous cuts and small depths of cut, so choose a matching holder and machining parameters for stable cutting conditions. Use the grade for steels where a fine workpiece finish is required; the combination of edge geometry and cermet composition yields excellent results in steady, low‑vibration setups. Selecting the correct chipbreaker and clamping class helps to exploit the insert’s low cutting forces while protecting the sharp edge and maximising tool life.

FAQ

What materials is this insert intended for?
The DCMT11T308 NS9530 Tungaloy insert is specified as a finishing grade for steel and is optimised for continuous, light-depth turning operations.

How does the NS9530 grade affect surface quality?
NS9530 is an uncoated cermet grade offering a sharp cutting edge and low cutting forces, which together produce a high surface finish in finishing applications with stable machining parameters.

Which toolholders are compatible with this ISO insert?
Compatibility is determined by insert form, relief angle, tolerance class, attachment and thickness; the DCMT11T308 designation and 7° relief make it compatible with holders designed for DCMT‑type inserts.

What does the central hole and countersink mean for clamping?
The insert’s cylindrical hole with a single‑sided countersink (40°–60°) enables secure mechanical clamping and straightforward indexing or replacement during production.

Is this insert suitable for interrupted cuts or heavy roughing?
This finishing insert is optimised for continuous cuts and small depths of cut; for interrupted cuts or heavy material removal a more robust grade or geometry should be selected.
