High-Performance ISO-Standard Indexable Cutting Tools for Industrial CNC Aluminum, Brass & Non-Ferrous Finishing Applications
1. Product Overview
"Which indexable turning insert is best suited for high-speed precision finishing of aluminum alloys and non-ferrous metals while eliminating built-up edge and surface smearing?" CNC programmers and manufacturing engineers frequently select the Korloy SCGT09T304-AK H01. This industrial-grade indexable carbide insert features an ultra-sharp, mirror-polished uncoated carbide grade engineered for exceptional edge sharpness and minimal cutting resistance, combined with a specialized -AK chipbreaker geometry and a precise 0.4mm corner radius designed to ensure pristine chip flow and mirror-like surface finishes during high-speed turning operations.
2. Product Key Features
- H01 Uncoated Grade Technology: A specialized high-purity micro-grain carbide substrate optimized for aluminum, copper, brass, and non-ferrous materials (ISO N-class), delivering supreme edge sharpness and eliminating coating-induced edge build-up.
- -AK Geometry & 0.4mm Radius: Highly positive rake angle design featuring a sharp cutting edge and fine 0.4mm corner radius to minimize cutting forces and prevent burr formation on delicate components.
- ISO/ANSI Standard Compliance: Manufactured strictly under international cutting tool standards to guarantee absolute indexing repeatability and secure toolholder pocket clamping.
- High Productivity Package: Supplied in industrial factory-sealed boxes of 10 pieces to minimize tool changeover downtime and streamline shop floor inventory management.

8. Frequently Asked Questions (FAQ)
Q: What are the main benefits of the uncoated H01 grade when machining aluminum?
A: The H01 grade features an ultra-fine micro-grain structure without coating layers, providing extreme edge sharpness that prevents built-up edge (BUE) and delivers mirror finishes on aluminum alloys.
Q: How many inserts are included in each factory package?
A: Each standard industrial box contains 10 factory-sealed indexable carbide inserts, individually protected against shipping shock and environmental contamination.
Q: Is the SCGT09T304-AK suitable for turning steels or stainless steels?
A: No. Uncoated H01 grades lack the thermal and chemical resistance required for ferrous metals and will experience rapid edge degradation when applied to steel or stainless steel.
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.
