CNMG 120416 T9215 CNMG turning insert by Tungaloy — CVD-coated carbide, 1.6 mm nose radius

CNMG120416 T9215 is an ISO-standard rhombic turning insert designed for external and internal turning in medium steel applications, combining robust wear resistance with stable chip formation

• ISO rhombic CNMG form
• CVD-coated carbide grade T9215
• Double-sided insert for economical indexing
• Cylindrical hole for secure clamping

High productivity through wear-resistant CVD-coated carbide

The first priority for efficient series turning is predictable tool life. The CVD-coated carbide T9215 offers a balance of high wear resistance and fracture toughness that supports longer tool life in continuous and lightly interrupted cuts. This behaviour reduces downtime for index changes and contributes directly to production-rate stability. The combination of coating and substrate allows for consistent edge condition over extended component runs, improving process economy in medium steel machining.

Secure mounting and proven ISO compatibility reduce set-up time

Compatibility with tooling systems is governed by geometry and tolerances. The ISO rhombic insert form, cylindrical hole, and standard dimensions simplify selection of a matching external holder or boring bar: form, clearance angle, tolerance class, fastening method, size and thickness determine fit. The double-sided geometry gives two cutting edges per pocket, lowering consumable cost per edge and ensuring rapid, repeatable tool indexation. The 0° clearance angle and 4.76 mm thickness contribute to stable seating and reduced chatter when the correct holder is used.

Application guidance for reliable component quality

This grade is optimised for turning of medium steel in continuous to light interrupted cutting conditions and is suitable for both external and internal operations. The 1.6 mm nose radius supports robust edge strength for general-purpose profiling while maintaining acceptable surface finish; for finer finishes, smaller radii should be considered. Selecting the matching chipbreaker and adapting speeds and feeds to the workpiece rigidity will yield the best balance between throughput and component quality, while the insert’s toughness helps resist edge chipping under variable cutting loads.

FAQ

What workpiece materials suit this insert best? This insert in grade T9215 is optimised for medium steels; the CVD-coated carbide provides wear resistance and toughness for continuous to light interrupted turns.

How is the insert mounted in the tool holder? The rhombic CNMG geometry with a cylindrical hole requires a compatible ISO external holder or boring bar; compatibility depends on form, clearance, tolerance class, fastening, size and thickness.

What cutting conditions are recommended for longest tool life? For the T9215 grade, stable setups with continuous cuts or only light interruptions deliver the best tool life; adjust speed and feed to workpiece rigidity and choose the appropriate chipbreaker.

How many effective cutting edges does the insert provide? The double-sided configuration offers two usable edges per side, enabling economical indexing and reduced consumable costs.

Is this insert suitable for interrupted cuts or unstable setups? It is suitable for light interruptions thanks to its fracture-resistant substrate, but heavy interruptions or unstable setups may require a tougher geometry or different grade.
