DNMG150404 T6215 indexable insert for Turning – Tungaloy

DNMG150404 is a rhomboidal ISO indexable insert engineered for stable to lightly interrupted turning of stainless steel in ISO-compatible holders

• CVD-coated carbide for improved wear resistance
• Optimised for stainless steel turning
• Rhomboid 55° geometry with 0.4 mm radius
• Double-sided indexable insert with cylindrical hole

High productivity from a wear-resistant grade

The T6215 grade is a CVD-coated carbide developed for demanding turning of stainless steel. The coating improves flank and crater wear resistance, extending tool life under continuous or lightly interrupted cuts. For production environments where component consistency matters, the insert’s enhanced durability means fewer changeovers and steadier cycle times. In practical terms, the hardened coating reduces the rate of edge degradation, helping to maintain dimensional stability across a batch run.

Reliable fit and quick indexing for reduced downtime

Supplied as an ISO-standard rhomboidal insert, compatibility with the clamping system is determined by form, relief angle, tolerance class, attachment and thickness. The standardised geometry simplifies holder selection and replacement: the insert indexes on the existing seat without special adjustments. The presence of a central cylindrical hole and double-sided cutting edges allows two usable edges per side, promoting cost-efficiency and faster tool rotation in series production. This configuration directly contributes to lower machine downtime and more predictable maintenance intervals.

Edge geometry that balances strength and finish

The rhomboidal shape with a 55° approach angle and 0.4 mm corner radius offers a compromise between edge strength and surface quality. The moderate corner radius increases robustness for medium-depth cuts while still supporting acceptable surface finish when chosen appropriately. For fine finishing operations, selecting a smaller radius or adjusting cutting parameters will refine the result, whereas for heavy roughing the geometry helps resist chipping. The insert’s double-sided layout further supports repeatable edge changes without recalibration, maintaining process stability.

Application guidance and process alignment

Designed primarily for external and internal turning, the insert performs best when the chipbreaker and the T6215 grade are selected according to workpiece stability and cutting mode. For interrupted cuts or unstable setups a softer cut and conservative parameters will preserve the edge; for continuous turning the grade’s wear resistance enables higher material removal rates. The ISO plate dimensioning and ease of holder matching mean the insert can be integrated into existing tool systems with minimal adaptation.

FAQ

What materials is this insert suitable for? The DNMG150404 T6215 indexable insert is formulated for machining stainless steel and is suitable for a broad range of stainless grades under stable to lightly interrupted conditions.

How many usable edges does the insert provide? Thanks to the double-sided design and central cylindrical hole, the insert offers multiple indexable edges to prolong tool life and reduce tooling costs.

What does the T6215 grade mean for process choice? T6215 denotes a CVD-coated carbide grade optimised for wear resistance in turning applications; it supports higher cutting lengths before edge loss compared with uncoated grades.

Is the insert compatible with standard ISO holders? Yes. The insert follows ISO geometry; compatibility depends on form, relief angle, tolerance class, attachment, size and thickness to match the holder’s pocket and clamping system.

Which cutting geometry affects surface finish the most? The 0.4 mm corner radius and 55° approach angle are the primary determinants: the radius balances edge strength and finish, while the approach angle influences chip flow and cutting forces.
