CNMG 090308 T6215 ISO turning insert for turning — Tungaloy

CNMG 090308 T6215 is a rhombic ISO turning insert designed for external and internal turning operations; the insert suits stable to slightly interrupted cuts and is optimised for machining stainless steels with a CVD-coated carbide grade.

• ISO rhombic CNMG 090308 geometry
• CVD-coated carbide grade T6215
• Double-sided chipbreaker for stainless steel
• 0° clearance and 3.18 mm thickness

Durable grade for steady production runs

The CVD-coated carbide T6215 offers high wear resistance, which reduces the frequency of index changes in batch and continuous production. The coating stabilises the cutting edge under the heat and work-hardening tendencies of stainless steel, so tool life becomes more predictable and process planning simpler. This controlled wear translates into fewer machine stops and a more economical machining cycle without compromising dimensional stability or repeatability.

Geometry and clamping that improve process security

The ISO rhombic geometry in combination with the 0° clearance and the 3.18 mm thickness provides a rigid contact area between insert and holder. The cylindrical hole and standard ISO form ensure compatibility with widely used external holders and boring bars, reducing the risk of incorrect seating and vibration. As a result, setup consistency is improved and the likelihood of chatter or uncontrolled deflection during turning is minimised, supporting higher-quality surface finishes.

Chip control and surface integrity for stainless applications

Equipped with a double-sided chipbreaker, the insert shapes chips reliably when turning ductile, work-hardening alloys. The designed chip flow reduces the tendency to form long, stringy chips and eases evacuation from the cutting zone, which helps maintain steady cutting forces and prevents rubbing. The outcome is improved surface integrity and fewer secondary operations for rework, which supports tighter production schedules and better first-pass yields.

Fast integration into existing tool systems and dependable supply

Being an ISO-standard insert, the item integrates into established toolholding systems with minimal adjustment. The standardised dimensions and the proven CVD-coated carbide construction simplify tool selection across mixed-material production. Backed by Tungaloy’s manufacturing expertise, the insert supports reproducible results and consistent edge quality, giving process engineers a pragmatic combination of performance and reliability for production turning.

FAQ

Is the insert compatible with standard CNMG holders?
The CNMG090308 T6215 insert follows ISO rhombic dimensions and the cylindrical-hole design, so it is compatible with standard CNMG external holders and boring bars when the holder accepts the 09 size and the specified thickness.

Which materials are recommended for this grade?
The T6215 grade is formulated and coated for stainless steel machining under stable to lightly interrupted conditions; it performs well where work hardening and abrasion are primary concerns.

Can the insert be used in interrupted cuts?
This insert is suitable for stable to slightly interrupted cuts; heavy interruptions or highly unstable setups may require a geometry or grade tailored for shock resistance.

How does the double-sided chipbreaker benefit the process?
The double-sided chipbreaker improves chip control for ductile alloys, promoting short, controllable chips and reducing the risk of chip entanglement, which supports surface quality and unattended run times.
