CNMG120402 120402 T9215 — Tungaloy turning insert (rhombic, 0° rake)

The CNMG120402 T9215 is a rhombic ISO turning insert designed for external and internal turning in medium steel applications, combining a CVD-coated carbide grade with a double-sided chipbreaker for sustained productivity

• CVD-coated carbide for high wear resistance
• Rhombic CNMG 80° geometry, 0° rake angle
• Double-sided chipbreaker for consistent chip control
• 0.2 mm corner radius for balanced edge strength

High, consistent performance for medium-steel turning

The rhombic ISO insert delivers stable cutting under continuous to lightly interrupted conditions thanks to the T9215 CVD-coated carbide grade. The coating provides enhanced wear resistance while the substrate maintains fracture toughness, so component quality and tool life are optimised. For machining medium-strength steels, this combination reduces downtime through predictable tool change intervals and supports higher feed rates where process stability permits. The result is a measurable improvement in cycle time without compromising surface integrity.

Secure clamping and predictable compatibility

Designed to match ISO-holder geometries, the insert’s 80° cutting geometry and 0° rake require selection of a compatible external holder or boring bar that respects form, clearance angles and tolerance class. The insert features a cylindrical locating hole and standard thickness to ensure repeatable seating and clamping. When assembled correctly, the system minimises vibration and runout, improving dimensional repeatability and reducing the risk of unexpected edge failure in production environments.

Controlled chips and surface quality for reliable throughput

The double-sided chipbreaker is engineered to produce short, manageable chips in medium steel, helping to maintain uninterrupted material flow and safe evacuation. Together with the 0.2 mm corner radius, the insert offers a balance between edge strength and surface finish, allowing for light finishing passes as well as more substantial stock removal. For manufacturers prioritising consistent part quality and process reliability, the insert supports stable cutting forces and reduces rework rates.

Practical selection and application tips for workshop use

When choosing grade and geometry, match the T9215 grade to workpiece material and cutting conditions: it is intended as a first choice for medium steel machining where both wear resistance and breakage resistance are required. Select the insert size and thickness to suit the holder and application rigidity; ensure coolant strategy and cutting parameters are aligned with the grade’s capabilities to prolong tool life. Compatibility depends on holder form, free angle, tolerance class, fastening method, size and thickness — confirm these parameters before production trials.

FAQ

What applications suit this insert best? This CNMG120402 T9215 insert is intended primarily for external and internal turning of medium steels and performs well under continuous to lightly interrupted cutting conditions.

How does the T9215 grade affect tool life? The T9215 CVD-coated carbide offers improved wear resistance and good fracture toughness, which together extend the service life of the Tungaloy insert in medium steel machining.

Is the insert reversible and how many cutting edges are available? The rhombic CNMG shape with a double-sided chipbreaker provides multiple indexed cutting edges per insert, enabling economical use of each cutting face.

Which holders are compatible with this ISO insert? Compatibility is determined by holder form, clearance angle, tolerance class, fastening and insert size; the CNMG120402 fits holders designed for CNMG 120402 geometry with a matching locating feature.

Can this insert handle interrupted cuts? Yes — the insert and grade combination is suitable for continuous to slightly interrupted cuts; for heavier interruptions, choose a geometry and grade adapted to greater shock loads.
