CNMG 120404 T9205 ISO turning insert — CVD-coated carbide, 0.4 mm nose radius, 80° geometry — Tungaloy

CNMG 120404 T9205 is an ISO-format turning insert for productive external and internal turning, designed for stable cutting conditions and higher cutting speeds.

• CNMG ISO 120404 geometry
• CVD-coated carbide grade T9205
• 0.4 mm nose radius for precision
• Double-sided chipbreaker with hole

Productive turning with a wear-resistant grade

The insert combines a CVD-coated carbide substrate with the T9205 grade to deliver a wear-resistant cutting edge optimised for productive turning of steel under stable machining conditions. The coating increases edge life at elevated cutting speeds, reducing tool changes and supporting a smoother production flow. The wear characteristics are balanced to provide consistent performance across batch and single-part production runs, contributing to measurable process stability and lower unit costs.

Precision geometry for consistent surface quality

A 0.4 mm nose radius and the rhombic 80° geometry ensure reliable part finish and dimensional control when turning profiles and external contours. The 0° clearance angle and 12 mm inscribed size maintain predictable chip formation, while the cylindrical hole supports secure clamping in standard ISO holders. For users less familiar with insert geometry: the nose radius affects surface finish and strength at the cutting edge, and the lead/approach angle (80°) determines how the insert engages the workpiece—together they influence feed, surface texture and tool life.

Fewer interruptions and easy logistics for the workshop

The double-sided design and reversible chipbreaker allow two usable cutting edges per side, improving economy per insert and reducing downtime for replacements. Conformity with ISO turning insert standards simplifies holder selection and inventory management; the system comprises the insert, matching external holder or boring bar, a clamp pad and fastening screw set. Choosing an ISO-standard insert reduces administrative complexity and helps maintain steady throughput on both manual and CNC turning centres.

Application advice and compatibility overview

The grade is intended primarily for turning of steel where stable clamping and machine rigidity are given; matching the chipbreaker and grade to the material and operation is essential for optimum results. The insert works well in general external and internal turning tasks where higher cutting speeds and reliable chip control are required. When in doubt about holder fit or recommended cutting data, technical consultation is advised to select the correct holder geometry, tolerance class and screw specifications to ensure safe and repeatable performance.

FAQ

What workpiece materials is this insert best suited to?
The CNMG 120404 T9205 insert is a wear-resistant CVD-coated carbide grade optimised for productive turning of steel under stable machining conditions; selection of chipbreaker should match the exact steel grade and operation.

Is the insert reversible and how many cutting edges are available?
This rhombic, double-sided insert offers multiple usable edges per index; the double-sided chipbreaker increases economy per insert and reduces downtime compared with single-sided alternatives.

Which holder types are compatible with the CNMG 120404 geometry?
ISO-format external turning holders and compatible boring bars that accept CNMG inserts with a cylindrical hole and ISO clamping provisions are suitable; compatibility is determined by form, clearance angle, tolerance class, fastening and plate thickness.

Does the grade require special cutting speeds or feeds?
The T9205 grade is intended for higher cutting speeds in stable conditions; recommended cutting data depend on material, machine rigidity and holder choice—consult machining data charts or technical advisers for exact parameters.

What is the manufacturer article number and origin of the insert?
The insert is listed under manufacturer article number 6785767 and is supplied as a brand-new Tungaloy indexable insert with SKU 6785767-Tungaloy.
