Product Overview
The Kyocera DNMG150608C CA315 TMD02411 is a precision-manufactured indexable carbide turning insert designed for modern CNC machining centers. Built on a fine-grained tungsten carbide substrate and finished with a multi-layer PVD coating, this insert delivers consistent performance across steel, stainless steel, and cast iron applications.
With its 55° Rhombic (Diamond) geometry and finishing chipbreaker profile, the DNMG150608C is optimized for finishing, semi-finishing operations where surface finish is the primary objective. The 0.8 mm nose radius ensures stable cutting action while maintaining dimensional accuracy over extended tool life.

Application Map by Operation
Use this map to determine the suitability of the DNMG150608C for common turning operations:
| Operation | Suitability | Notes |
|---|---|---|
| External Longitudinal Turning | Excellent | Low feed finishing, superior surface quality |
| Face Turning | Good | Light cuts on flat surfaces |
| Profiling | Excellent | Precise contour following with small DOC |
| Grooving | Fair | Limited by nose radius |
| Threading | Not Recommended | Use dedicated threading inserts |
Recommended Cutting Conditions
The following parameters represent starting recommendations. Optimize based on machine rigidity, workpiece condition, and coolant delivery:
| Parameter | Carbon Steel | Stainless Steel | Cast Iron |
|---|---|---|---|
| Cutting Speed (Vc) | 200–280 m/min | 120–180 m/min | 150–220 m/min |
| Feed Rate (fn) | 0.10–0.25 mm/rev | ||
| Depth of Cut (ap) | 0.5–2.0 mm | ||
| Priority | Surface finish | ||
Note: Values are starting recommendations. Reduce speed by 15–20% for hardened materials or interrupted cuts. Increase feed up to 0.6 mm/rev for heavy roughing with KG/KH geometries.
Operating Guidelines
Adhering to these guidelines ensures maximum tool life, surface quality, and process safety:
- Use minimum coolant pressure of 5 bar for chip evacuation in blind holes
- Maintain consistent feed rate below 0.25 mm/rev for best surface finish
- Recommended wiper geometry pairing for Ra < 0.8 µm surface finish
- Avoid interrupted cuts exceeding 20% of engagement time to preserve edge
- Use precision toolholder with runout < 0.01 mm for optimal results
