The Original Korloy DNMG150604-HA PC9030 (ANSI Standard: DNMG 441) is a high-performance 55° diamond insert engineered for extreme stability in difficult-to-machine materials. By combining an industrial-strength 6.35mm thickness with the ultra-sharp, mirror-polished HA chipbreaker, this insert solves the most challenging problems in "gummy" metal turning. The PC9030 PVD coating provides the necessary heat resistance, while the polished HA groove ensures that even the most adhesive materials like Titanium and 316L Stainless glide off the cutting edge without welding.
The Anti-Vibration Specialist: The added mass of the 1506 series body acts as a stabilizer for long-reach turning and deep boring. When paired with the razor-sharp HA geometry, it significantly reduces cutting pressure, preventing work-hardening and surface tearing on sensitive alloys.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DNMG150604-HA |
| ANSI Code | DNMG 441 |
| Grade | PC9030 (Premium PVD for Stainless/Heat-Resistant) |
| Thickness | 6.35 mm (Maximum Rigidness) |
Core Performance Benefits:
- Polished HA Geometry: Reduces friction and prevents built-up edge (BUE) on materials like Titanium, Pure Nickel, and soft Stainless Steel.
- Industrial 1506 Thickness: 33% thicker than standard 1504 inserts, providing superior heat dissipation and vibration dampening.
- PVD Nanostructured Coating: Optimized for wet machining, resisting thermal shock and chemical wear in high-temperature alloys.
- High Edge Sharpness: Effectively cuts through material rather than "pushing" it, resulting in exceptional dimensional accuracy.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Gummy Stainless (304/316) | 100 - 180 m/min | 0.05 - 0.18 mm/rev | 0.15 - 1.5 mm |
| Titanium Alloys (Ti-6Al-4V) | 40 - 90 m/min | 0.05 - 0.15 mm/rev | 0.10 - 1.2 mm |
| Nickel-Based (Inconel) | 25 - 55 m/min | 0.05 - 0.12 mm/rev | 0.10 - 1.0 mm |
Compatible Tool Holders:
Must be used with holders designed for the 1506 (6.35mm thick) pocket:
- External Turning: DDJNR/L 2525M15 / 3232P15
- Internal Boring Bars: S32T-DDUNR15 / S40U-DDUNR15 / S50V-DDUNR15
Unique Edge: 1506-HA vs. 1506-HM
Why use the HA chipbreaker on a PC9030 stainless grade?
Features a mirror-polished top face. Best for Adhesive Metals. Use this when your stainless steel is "sticking" to the tool or when machining Titanium to prevent surface smearing.
Features a standard honned edge. Best for General Stainless Steel turning. It is more robust for removing material but lacks the extreme sharpness of the HA groove.
Machinist's Pro Tip: If you are getting a "torn" look on your 316 stainless finish, it's often caused by the material welding to the tool tip. This HA polished version is the secret weapon to achieving a bright, clean finish in those scenarios.
Packaging: 10 pieces per box.
