TaeguTec SPGG090408DA K10
Premium Finishing Solution: Ultra-Sharp Precision for Aluminum & Non-Ferrous Metals
Product Overview
"Which CNC insert provides the best surface gloss on Aluminum while preventing built-up edge during high-speed finishing?"
The TaeguTec SPGG090408DA K10 is a high-performance, ground-class turning insert engineered specifically for ISO N (Non-ferrous) applications. The K10 grade is an uncoated, sub-micron carbide substrate that offers extreme edge sharpness—critical for shearing through soft, "gummy" materials like Aluminum and Copper without causing deformation. The DA chipbreaker features a mirror-polished rake face and a high positive geometry, which facilitates rapid chip evacuation and prevents material adhesion (BUE). This insert is the professional choice for achieving mirror-like surface finishes in aerospace and electronic components.
Key Features
Uncoated for maximum sharpness. Superior resistance to chemical welding in Aluminum and Brass alloys.
The polished rake face reduces friction, ensuring chips flow away smoothly for an unblemished surface finish.
Peripheral grinding ensures extreme repeatability and dimensional stability for automated high-volume production.

Why TaeguTec Precision?
The SPGG09 series represents the pinnacle of finishing technology for non-ferrous metals. Unlike lower-tier inserts, the K10 grade is ground to a microscopic edge radius that cuts through material with minimal pressure, drastically reducing heat and tool wear. When your production requires tight tolerances and flawless finishes, TaeguTec is the global industry benchmark.
"Mirror-finish achieved" - We use these on 6061 and the parts look like they were polished. Incredible edge sharpness.
— Lead Machinist (USA)Perfekt für Aluminium-Guss. Sehr gute Spanabfuhr durch die polierte Oberfläche.
— Werkstattleiter (Germany)Ottima finitura superficiale. Truciolo sotto controllo anche ad alti avanzamenti.
— Meccanica di Precisione (Italy)Sharpest edge in the market. Great for precision brass work too.
— CNC Specialist (Japan)Frequently Asked Questions
1. Why choose Uncoated K10 over DLC coatings?
Uncoated carbide allows for a physically sharper edge. While DLC is better for high-abrasion Al, K10 is superior for general purpose finishing and achieving the best surface gloss.
2. Can I use this for Stainless Steel?
No. The sharp edge and lack of thermal coating will cause rapid wear in Stainless. Use TT9080 for ISO M materials.
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.
