KORLOY DNMG150408-HA H01 Indexable Carbide Turning Inserts | DNMG432-HA H01 (ANSI Equivalent) Uncoated Carbide Inserts for Aluminum and Non-Ferrous Metal Machining - 10pcs/box
High-Precision ISO-Standard 55° Rhombic Negative Indexable Turning Cutters Featuring KORLOY H01 High-Purity Uncoated Carbide Substrate and -HA Sharp Finishing Chipbreaker for Superior Edge Sharpness, Low Cutting Forces, and Built-Up Edge Prevention in Aluminum and Non-Ferrous Alloy Machining
1. Product Overview
"Which indexable turning insert provides the exceptional edge sharpness and mirror-like surface finish required for high-speed machining of aluminum and non-ferrous alloys without material adhesion?" Advanced manufacturing engineers and CNC operators frequently look to the KORLOY DNMG150408-HA H01. This industrial-grade turning insert combines KORLOY's specialized H01 high-purity uncoated carbide grade with a mirror-polished rake face and an -HA sharp finishing chipbreaker geometry. Engineered with a 55° rhombic negative layout, a 15mm cutting edge length, a 4.76mm thickness ('04'), and an 0.8mm corner radius, it delivers outstanding resistance to built-up edge (BUE) and thermal shock, ensuring maximum productivity and flawless surface integrity during non-ferrous finishing.
2. Product Key Features
- H01 High-Purity Uncoated Grade: Formulated with a fine-grain micro-structure and a mirror-polished rake face that completely eliminates coating-induced chip welding when cutting gummy non-ferrous materials.
- -HA Sharp Finishing Geometry: Features a razor-sharp cutting edge engineered to minimize cutting forces, suppress vibration during slender part turning, and achieve pristine surface finishes.
- 55° Rhombic Versatility: The acute 55-degree apex angle provides exceptional tool clearance for complex profiling, contouring, and multi-directional turning operations.
- Factory Sealed Packaging: Delivered in genuine KORLOY containers containing 10 premium indexable inserts.
