TaeguTec SPGG110408DA K10
Precision Finishing Expert: Mirror Surfaces for Aluminum & Non-Ferrous Alloys
Product Overview
"Which CNC insert provides the most consistent mirror finish on Aluminum while effectively preventing Built-Up Edge (BUE)?"
The TaeguTec SPGG110408DA K10 is a high-performance, ground-class turning insert specifically engineered for ISO N (Non-ferrous) materials. The K10 grade is an uncoated, sub-micron carbide substrate that offers extreme edge sharpness, which is critical for shearing through soft, adhesive materials like Aluminum without causing burrs or deformation. Its DA chipbreaker features a mirror-polished rake face and a high positive rake angle, optimized to force chips away from the workpiece instantly. This ensures maximum surface integrity and dimensional accuracy in high-speed CNC precision turning.
Key Features
Fine-grain structure for maximum edge toughness and sharpness. Uncoated to eliminate the "rounding" effect of coatings, ensuring a razor-sharp cut.
Highly polished DA chipbreaker reduces friction and prevents "sticking" (BUE), resulting in a flawless surface gloss.
Precisely ground periphery ensures extreme repeatability and tight dimensional control in precision Swiss-type or CNC lathes.

TaeguTec Grade Comparison (ISO N)
Uncoated fine-grain carbide. The industry standard for Aluminum. Maximum sharpness.
Diamond-like carbon coated. Best for highly abrasive high-silicon aluminum (>12% Si).
Why Professional Machinists Choose TaeguTec
The SPGG110408DA K10 represents the peak of non-ferrous finishing technology. Unlike generic inserts, TaeguTec’s K10 grade substrate is engineered for chemical stability against aluminum adhesion. When your shop requires mirror finishes and 100% repeatability, TaeguTec provides the technical edge to outperform the competition.
"Unbelievable Gloss" - We use these on 6061 components. The surface is so smooth it looks like it was already polished.

1. Can this insert be used for Stainless Steel?
No. The sharp edge and lack of thermal coating make it unsuitable for ISO M (Stainless). For stainless, we recommend TaeguTec TT9080 coated grades.
2. Why choose K10 uncoated over PVD coating for Aluminum?
Uncoated K10 allows the sharpest possible microscopic edge radius. In "gummy" materials like aluminum, a sharper edge is more effective than a coating at preventing Built-Up Edge.
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.
