Product Overview
The DNMG150608PQ is a premium-grade negative turning insert with hole from Kyocera, engineered for heavy duty operations in modern CNC turning centers. Featuring the advanced CA525 PVD-coated carbide substrate and the PQ – Heavy Duty geometry, this insert delivers exceptional wear resistance, predictable tool life, and superior surface integrity across a broad spectrum of steel workpiece materials.
Manufactured to stringent ISO tolerances, the DNMG150608PQ is ideal for high-volume production environments where consistency, reliability, and cost-per-edge optimization are critical. Whether deployed in external turning, facing, or copy-turning operations, this insert maintains dimensional accuracy and minimizes downtime through extended edge life.

Grade Details – Key Grade Characteristics
The CA525 grade is a high-performance PVD-coated carbide substrate developed specifically for ISO P-group materials (steels and cast steels). It combines a fine-grained tungsten carbide matrix with a multi-layer physical vapor deposition coating for exceptional thermal stability and crater wear resistance.
| Characteristic | Specification |
|---|---|
| Coating Technology | Multi-layer PVD (TiAlN-based) – optimized for high-speed steel machining and reduced built-up edge |
| Substrate | Fine-grained WC-Co (6% Co) with high hardness and transverse rupture strength |
| Hardness (HV30) | 1,550 ± 50 HV – provides excellent abrasion resistance at elevated temperatures |
| ISO Application Range | P15 – P30 (steels, cast steels, ferritic/martensitic stainless steels) |
| Max Cutting Temp. | 800 °C (1,472 °F) – coating retains integrity under heavy mechanical loads |
| Color Code | Bronze/Copper – visual grade identification for quick tool-crib management |

Application Map by Operation
| Operation | Suitability | Notes |
|---|---|---|
| External Longitudinal Turning | ★★★★★ | Primary application; excellent chip control and surface finish |
| Facing | ★★★★☆ | Use reduced feed near center to avoid chip crowding |
| Profiling / Contouring | ★★★☆☆ | Limited by nose radius; use smaller radius for fine contours |
| Parting / Grooving | ★★☆☆☆ | Not recommended; use dedicated parting inserts |
| Threading | ★☆☆☆☆ | Not applicable; use full-profile threading inserts |
| Boring (Internal) | ★★★★☆ | Compatible with DNMG/DNMX on internal toolholders; ensure chip evacuation |
Recommended Cutting Conditions
Parameters below are starting recommendations for continuous cuts in carbon steel (C45 / 1045) using coolant. Adjust based on machine rigidity, workpiece condition, and desired tool life.
| Parameter | Roughing | Semi-Finish | Finishing |
|---|---|---|---|
| Cutting Speed (Vc) | 100 m/min | 160 m/min | 220 m/min |
| Feed Rate (fn) | 0.60 mm/rev | 0.45 mm/rev | 0.30 mm/rev |
| Depth of Cut (ap) | 8.0 mm | 5.2 mm | 2.5 mm |
| Coolant | Emulsion 6–8% | Emulsion 6–8% | Emulsion 6–8% or Dry |
Operating Guidelines
- Toolholder Selection: Use Kyocera-approved toolholders with matching insert pocket angles. Ensure clamping mechanism is free of debris and operates smoothly.
- Run-out Check: Maintain TIR (total indicator run-out) below 0.02 mm at the insert corner to prevent uneven wear and premature chipping.
- First Cut Protocol: Reduce initial feed by 30% for the first 30 seconds to "season" the cutting edge and stabilize thermal gradients.
- Chip Management: Verify chip curl and evacuation every 10 minutes of continuous operation. Adjust coolant nozzle to target the rake face directly.
- Edge Inspection: Inspect the flank wear land (VB) after each batch. Retire inserts when VB exceeds 0.3 mm or when crater wear reaches the cutting edge.
- Storage: Store inserts in original packaging away from direct sunlight and corrosive atmospheres. Avoid mixed storage with ferrous debris.
