CPMT 09T302 NS9530 CPMT — Turning insert for fine finishing, Tungaloy

A CPMT09T302 NS9530 indexable insert engineered for precision external and internal turning, optimised for finishing of steel with low cutting forces and an emphasis on surface quality

• ISO indexable insert CPMT 09T302 NS9530
• Uncoated cermet for fine finishing
• Rhombic shape, 80° cutting edge
• 0.2 mm corner radius, single-sided chipbreaker

Exceptional surface quality for finishing operations

The insert is manufactured from uncoated cermet (NS9530), a grade designed specifically as a finishing material for steel. This composition provides a sharp cutting edge and reduced cutting forces, which together lower the mechanical stress on the workpiece and the toolholder. The outcome is a consistently improved surface finish and fewer secondary operations. For continuous cuts and small depths of cut the material-grade selection minimises burr formation and supports predictable, tight tolerances. The described behaviour is particularly relevant for precision turning where consistent part finish and short cycle-time variability are priorities.

Secure, ISO-standard compatibility with conventional holders

Compatibility with clamping systems follows ISO conventions: form, clearance angle, tolerance class, fastening method, size and thickness determine interchangeability. The insert’s ISO designation (CPMT09T302) and its rhombic geometry ensure straightforward matching to common external holders and boring bars. Because the system comprises the insert, a corresponding external holder or boring bar, backing pad or clamp set and replacement screws, workshops benefit from rapid changeovers and reproducible seating. This standardisation reduces setup time and the risk of incorrect mounting, supporting stable machining processes and less rework.

Stable clamping and controlled chip formation

Mechanical details such as the cylindrical location hole with single-sided countersink (40°–60°) and a plate thickness of 3.97 mm provide robust seating and repeatable clamping. The combination of an 80° cutting edge and a 0.2 mm corner radius keeps the cutting line stable while the single-sided chipbreaker promotes predictable chip flow during finishing passes. These characteristics assist in maintaining a durable cutting edge and in preventing unstable chip patterns that could affect surface integrity. For short, uninterrupted cuts this configuration delivers consistent results with minimal manual intervention.

Practical application guidance for turning shops

The geometry and grade are aimed at external and internal turning where surface quality is critical. The insert is particularly suited to finishing operations on steel using small depths of cut and continuous feed conditions. Selection of the correct chipbreaker and grade should match the workpiece material, machining mode and machine-tool rigidity to fully exploit the insert’s advantages. In production environments this leads to fewer part rejections and a smoother production flow, while smaller shops gain the benefit of easier process setup and reduced trial-and-error.
