High-Performance ISO-Standard 55° Rhombic Positive Micro Indexable Turning Cutters for Industrial Swiss Lathes, CNC Aluminum Alloys, Copper & Precision Medical Components
1. Product Overview
"Which micro indexable turning insert is best suited for Swiss-type CNC lathe operations requiring tight tolerance precision finishing on small aluminum and non-ferrous components without burrs or built-up edge?" CNC programmers and precision machine shop supervisors frequently select the Korloy DCGT070202-AK H01. This industrial-grade miniature indexable carbide turning insert features an advanced high-purity H01 uncoated micro-grain carbide grade optimized for non-ferrous metals and plastics, combined with a 55° rhombic positive geometry, an ultra-precise 0.2mm corner radius for tight corner profiling and fine finishing, and a specialized -AK chipbreaker engineered to provide low cutting resistance, smooth chip control, and mirror-like surface integrity during delicate micro-machining passes.
2. Product Key Features
- H01 Uncoated Micro-Grain Grade Technology: A specialized high-purity binderless micro-grain carbide substrate ground to an extreme edge sharpness that eliminates built-up edge when machining soft aluminum and copper.
- Optimized -AK Chipbreaker Geometry: Sharp positive rake angle design with a polished top rake face engineered to lower cutting forces and deliver flawless surface finishes on miniature parts.
- ISO Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee secure screw-down locking and exact interchangeability across standard positive miniature turning tool holders and boring bars.
- Industrial Package: Supplied in factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline workshop inventory management.

8. Frequently Asked Questions (FAQ)
Q: Why is the 0.2mm small corner radius (-02) chosen for Swiss lathe precision finishing?
A: The 0.2mm corner radius provides a tighter profiling capability for sharp internal corners, fine shoulders, and micro-diameters where larger radii would cause undercutting.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable turning inserts, individually secured to prevent transit edge damage.
Q: Is coolant required when running the H01 grade on aluminum micro-components?
A: Yes, applying high-pressure water-miscible coolant is strongly recommended to evacuate micro-chips cleanly and maintain stable low temperatures during high-speed Swiss machining.

Technical FAQ & Buying Guide
Absolutely. Our CNC carbide inserts (including CNMG, WNMG, DNMG, and APMT series) are manufactured strictly adhering to international ISO/ANSI specifications. A CNMG 120408 from OYYU BEYOND will flawlessly fit any standard turning tool holder or indexable tool from major global brands like Sandvik Coromant, Kennametal, Iscar, Walter, or SECO, providing a highly cost-effective premium alternative without sacrificing tolerance or tool life.
We offer optimized CVD and PVD multi-layer coatings for different ISO material groups:
- For Carbon/Alloy Steel (ISO P): Choose our thick multi-layer CVD coated grades (e.g., Al2O3 + TiN). They provide exceptional crater wear resistance and thermal barriers during high-speed dry or wet roughing.
- For Stainless Steel (ISO M): Choose our nano-structured PVD coated grades with sharp, positive chipbreakers (like -TM or -MA). This combination prevents work hardening and effectively controls sticky chips.
The optimal cutting parameters vary depending on the workpiece hardness and operation type:
- For General Steel Turnings: Recommended cutting speed ($V_c$) ranges from 150 to 280 m/min, with a feed rate ($f$) of 0.15 to 0.45 mm/rev.
- For Stainless Steel Finishing: Recommended cutting speed ($V_c$) is 120 to 200 m/min, with a feed rate ($f$) of 0.10 to 0.25 mm/rev.Always adjust parameters based on early wear patterns: increase $V_c$ if built-up edge occurs, or reduce $V_c$ if severe flank wear is observed.
