CNMG 120416 T6215 — Indexable turning insert for stainless steel turning | Tungaloy

A CNMG120416 T6215 indexable insert designed for turning applications, offering a wear-resistant CVD-coated carbide grade for stable to slightly interrupted cuts on stainless steels.

• CVD-coated carbide grade T6215
• Optimised for stainless steel machining
• Rhombic 80° insert with 1.6 mm corner
• Double-sided chipbreaker, cylindrical hole

Increased uptime through wear-resistant coating and grade

The combination of a CVD-coated surface and T6215 cutting grade gives a clear performance advantage when machining stainless steel: the coating reduces flank wear and the substrate provides toughness against edge chipping. This results in longer tool life and fewer index changes, which directly improves process stability and reduces production interruptions. For shops aiming to raise throughput without sacrificing surface finish, the insert’s wear characteristics make it a dependable choice.

Simple compatibility and secure clamping for predictable results

Compatibility with toolholders depends on form, clearance angle, tolerance class, fastening method, size and thickness. The rhombic design with an 80° included angle and cylindrical hole matches standard CNMG-style holders; the 4.76 mm thickness and size 12 make it straightforward to pair with matching external holders or a boring bar. Using the correct underlay/clamp set and replacement screws ensures repeatable seating and consistent cutting geometry, which contributes to process reliability and reproducible part quality.

Improved chip control and surface finish in stable conditions

The double-sided chipbreaker is configured for turning operations and promotes efficient chip formation when combined with appropriate feeds and speeds. In stable to lightly interrupted cutting, the insert helps produce a consistent surface finish while managing chips safely out of the cut. Selecting the chipbreaker and grade according to the workpiece condition and machine rigidity delivers the best balance of productivity and component quality, supported by the Tungaloy design philosophy for productive cutting tools.

FAQ

Which materials is this insert most suitable for?
The CNMG120416 T6215 indexable insert (Tungaloy, SKU 6944548-Tungaloy) is designed primarily for stainless steel turning under stable to slightly interrupted conditions.

How is compatibility with toolholders determined?
Compatibility depends on the insert form, clearance angle, tolerance class, fastening type, size and thickness; the CNMG120416 fits standard CNMG holders when the holder matches the 12 mm size, 4.76 mm thickness and cylindrical-hole fastening.

When should the double-sided chipbreaker be chosen?
The double-sided chipbreaker is recommended when chip control and short-term stability are required; select this chipbreaker together with the T6215 grade for improved chip formation and surface quality on stainless steels.

Is the insert indexable and how many cutting edges are available?
The CNMG120416 insert is double-sided and indexable; each usable cutting edge should be rotated in sequence until wear dictates replacement.

What dimensions should be checked before ordering the insert?
Confirm the insert size (12 mm), thickness (4.76 mm), corner radius (1.6 mm), hole style (cylindrical) and clearance angle (0°) to ensure correct fit with the chosen holder.
