CNMG 120408 T6215 ISO turning insert for stainless steel — Tungaloy

CNMG120408 T6215 is an ISO-form indexable turning insert engineered for reliable external and internal turning of stainless steels under stable to lightly interrupted conditions

• CVD-coated carbide grade T6215
• For stainless steel turning
• Double-sided chipbreaker, rhombic insert
• Cylindrical-hole CNMG 120408, 0° clearance

Higher process stability through material and coating

The combination of a CVD-coated carbide substrate and the optimised T6215 grade provides a balance of wear resistance and toughness that suits demanding stainless steel machining. The coating reduces flank and crater wear, which translates into longer tool life and fewer insert changes. For production environments where consistent cycle times matter, this indexable cutting solution contributes to steady component quality and reduced downtime by maintaining edge integrity under typical turning loads.

Predictable chip control and clamping reliability

A double-sided chipbreaker and rhombic geometry ensure controllable swarf formation and evacuation, reducing the risk of built-up edge and surface defects. The insert’s cylindrical hole and defined tolerance class support secure mounting in standard ISO holders, so clamping repeatability is high and insert seating remains accurate across tool changes. The 0° clearance and 80° approach angle combine to give a stable cutting action that is particularly effective for finishing passes and light roughing where surface integrity is critical.

Practical benefits for workshop workflows

Specifying a standard ISO form such as this CNMG series plate simplifies tool inventory and holder compatibility, enabling faster setup and fewer special parts. The 12 mm size and 4.76 mm thickness provide robust edge support for turning operations, while the 0.8 mm corner radius offers a compromise between edge strength and surface finish. These measurable characteristics make process planning more predictable: feed and speed windows can be set with confidence, contributing to overall machining efficiency and cost-effectiveness.

FAQ

What materials is this insert suitable for?
The CNMG120408 T6215 turning insert from Tungaloy is designed primarily for stainless steel machining and performs well under stable to lightly interrupted cutting conditions.

How does the T6215 grade compare in wear resistance?
Tungaloy’s T6215 CVD-coated grade offers increased wear resistance and edge life compared with uncoated carbide, making it suitable where abrasion and moderate adhesion are concerns.

Is the insert reversible and how many cutting edges are available?
The rhombic CNMG geometry is double-sided, providing two usable cutting edges per side; the indexable format allows rotation to a fresh edge when required.

What holder compatibility should be considered?
Compatibility depends on form, relief angle, tolerance class, clamping method, size and thickness; the ISO CNMG120408 form fits standard ISO external holders designed for CNMG inserts.

Which SKU identifies this product for ordering?
Order using SKU 6944533-Tungaloy or refer to the manufacturer article number 6944533 for precise identification.
