The Original Korloy CNMG190616-HS PC9030 (ANSI Standard: CNMG 644) is a heavy-duty precision insert engineered for large-scale Stainless Steel and Heat-Resistant Super Alloy (HRSA) finishing. Featuring a massive 6.35mm thickness and 19mm edge length, the CNMG1906 series provides the ultimate stability required for machining large diameters. The HS chipbreaker is designed for high-precision shearing, while the 1.6mm nose radius offers an exceptional balance between surface finish quality and edge durability against work-hardening materials.
Superior Edge Strength: The R1.6 (1/16") radius is the professional's choice for machining abrasive stainless steels like 316 and Duplex. It provides a larger contact area to dissipate heat and withstand the pressure of semi-finishing passes.
Technical Specifications:
| Brand | Korloy (100% Genuine) |
| ISO Code | CNMG190616-HS |
| ANSI Code | CNMG 644 |
| Grade | PC9030 (Premium PVD for Stainless & HRSA) |
| Chipbreaker | HS (High-Speed Finishing) |
Core Performance Benefits:
- Reduced Work Hardening: HS geometry features a specialized sharp rake angle that cleanly shears stainless steel, preventing the surface from hardening during the pass.
- High Thermal Capacity: The large 1906 format acts as a heat sink, keeping the cutting edge cooler during long continuous cuts on large workpieces.
- Exceptional Finish: The 1.6mm radius provides a smooth surface even at higher feed rates, increasing productivity without sacrificing quality.
- PVD PC9030 Coating: Specifically developed for tough alloys, offering high resistance to notch wear and built-up edge (BUE).
Recommended Cutting Parameters:
| Material Group | Cutting Speed (Vc) | Feed Rate (f) | Depth of Cut (ap) |
|---|---|---|---|
| Stainless (304/316) | 90 - 160 m/min | 0.20 - 0.45 mm/rev | 0.5 - 4.5 mm |
| Duplex Stainless | 60 - 110 m/min | 0.18 - 0.35 mm/rev | 0.5 - 3.5 mm |
| Nickel Alloys / Titanium | 25 - 50 m/min | 0.15 - 0.30 mm/rev | 0.5 - 3.0 mm |

Finishing Pro-Tip: Radius Choice (R1.2 vs. R1.6)
Why choose the 1.6mm radius for your large stainless parts?
Best for strength and productivity. It handles larger depths of cut and prevents chipping in hard-to-cut alloys, making it safer for high-value large components.
Best for intricate finishing and machines with lower horsepower. It creates less radial pressure, which is better for long, slender workpieces.
Note: When using the 1.6mm radius, you can increase your feed rate (f) and still achieve the same surface roughness as a 1.2mm radius at a lower feed.
Packaging: 10 pieces per box.
