The Original Korloy DNMG150604-HS PC9030 (ANSI Standard: DNMG 441) is a specialized 55° diamond insert designed for ultra-stable finishing of Stainless Steel (M) and Exotic Alloys (S). Featuring an industrial-strength 6.35mm thickness, this insert provides the rigidness needed to eliminate chatter on large-scale workpieces. The HS (High-Sharpness) chipbreaker is the industry's answer to "bird-nesting" – it forces chip breakage even at extremely light depths and low feed rates, ensuring your finished surface remains flawless.
Heavy-Duty Precision: When precision finishing large stainless steel shafts or valves, heat and vibration are your enemies. The DNMG 441's thick body acts as a heat sink, while the HS geometry ensures chips are snapped and cleared instantly, preventing catastrophic chip tangling.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | DNMG150604-HS |
| ANSI Code | DNMG 441 |
| Grade | PC9030 (Premium PVD for Stainless) |
| Thickness | 6.35 mm (Maximum Rigidity) |
Core Performance Benefits:
- Superior Chip Breaking: The HS geometry is specifically tuned for finishing passes where depth of cut is minimal, preventing long, stringy chips.
- Vibration Dampening: The 1506 (6.35mm) thickness provides significantly more mass than standard 1504 inserts, absorbing harmonics for a smoother finish.
- PVD Nanostructured Coating: PC9030 offers an ultra-smooth surface that resists chemical adhesion (sticking) from 304/316 stainless steel.
- High Dimensional Accuracy: Sharp cutting action reduces tool pressure, preventing the "pushing" of the workpiece and ensuring tight tolerances.
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| 300-Series Stainless | 110 - 200 m/min | 0.05 - 0.15 mm/rev | 0.15 - 1.2 mm |
| Duplex Stainless | 60 - 110 m/min | 0.04 - 0.12 mm/rev | 0.15 - 1.0 mm |
| Titanium Alloys | 35 - 75 m/min | 0.05 - 0.10 mm/rev | 0.10 - 0.8 mm |
Compatible Tool Holders:
Must be used with holders designed for the 1506 (6.35mm thickness) pocket:
- External Precision Turning: DDJNR/L 2525M15 / 3232P15
- Heavy Boring Bars: S32T-DDUNR15 / S40U-DDUNR15 / S50V-DDUNR15
Thickness Advantage: DNMG 1506 vs. 1504
Why choose the "Thick" 150604-HS for precision finishing?
The 6.35mm thickness provides Ultra-High Thermal Capacity. On long finishing cuts in 316 stainless, this insert stays stable and cool, ensuring the nose radius doesn't degrade prematurely.
The standard 4.76mm thickness. Excellent for small components, but prone to micro-vibrations when used on heavy-duty lathes or during deep internal finishing.
Machinist's Insight: For automated CNC environments, HS + 1506 Thickness is the ultimate insurance policy. It stops bird-nesting and resists chatter, allowing for higher confidence in lights-out manufacturing.
Packaging: 10 pieces per box.
