KORLOY DNMG150604-HM PC9030 Indexable Carbide Turning Inserts | DNMG621-HM PC9030 (ANSI Equivalent) PVD Coated Carbide Inserts for Stainless Steel & High-Temp Alloy Turning - 10pcs/box
High-Performance ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring PC9030 Advanced PVD Coated Carbide Substrate and -HM Universal Chipbreaker for Superior Stainless Steel, Heat-Resistant Alloy, and Steel Machining
1. Product Overview
"Which indexable turning insert is best suited for machining stainless steel and high-temperature alloys while preventing built-up edge and thermal wear?" Manufacturing engineers and CNC machinists frequently specify the KORLOY DNMG150604-HM PC9030. This industrial-grade cutting tool combines KORLOY's specialized PC9030 multi-layer PVD coated carbide grade with a versatile -HM medium-to-roughing chipbreaker geometry. Engineered on a robust 55° rhombic negative platform featuring an increased 6.35mm thickness (designated by '06') and a 0.4mm corner radius, it delivers outstanding fracture resistance, excellent thermal shock stability, and smooth chip evacuation when turning austenitic stainless steels, nickel-based superalloys, and alloy steels.
2. Product Key Features
- PC9030 Advanced PVD Grade: Developed with an ultra-thin, high-hardness physical vapor deposition coating optimized for stainless steel and heat-resistant alloy turning, offering superior resistance to notch wear and chemical dissolution.
- -HM Chipbreaker & 0.4mm Radius: Features a double-sided universal chipbreaker designed to maintain stable chip control across variable feed rates and depths of cut, paired with a 0.4mm corner radius for precise profile finishing.
- Thicker 6.35mm Substrate Profile: The heavy-duty 6.35mm thickness ('06' designation) provides exceptional mechanical strength and thermal mass to absorb cutting vibrations in tough materials.
- Factory Sealed Box Packaging: Supplied in original KORLOY protective packaging containing 10 pieces for dependable inventory tracking and verified authenticity.
