TaeguTec SPGG07T308DA K10
Professional High-Sharpness Finishing: The Benchmark for Aluminum & Non-Ferrous Alloys
Product Overview
"Which CNC insert is best for achieving a mirror-like finish on Aluminum while eliminating Built-Up Edge (BUE)?"
The TaeguTec SPGG07T308DA K10 is a high-precision, ground-class turning insert specifically engineered for ISO N (Non-ferrous) materials. The K10 grade consists of an uncoated, sub-micron carbide substrate that allows for the sharpest possible cutting edge—a necessity for preventing material welding in "gummy" metals. The DA chipbreaker features a mirror-polished rake face and a high positive rake angle, designed to force chips away from the workpiece instantly. This combination ensures maximum surface integrity and tight dimensional tolerances in precision aerospace, medical, and electronic component manufacturing.
Key Features
Uncoated for maximum edge sharpness. Provides superior resistance to adhesion in Aluminum, Brass, and Copper.
The polished DA geometry reduces cutting friction, significantly improving chip evacuation and surface gloss.
Full peripheral grinding ensures high repeatability and stability, making it ideal for high-precision finishing operations.

TaeguTec Grade Benchmarking
Uncoated. Best for preventing adhesion and achieving maximum surface gloss in Al.
Diamond-like carbon coated. Preferred for highly abrasive high-silicon aluminum.
Why TaeguTec Precision?
TaeguTec's SPGG series represents the pinnacle of finishing technology. The K10 grade edge is ground to a microscopic sharpness that generic inserts cannot replicate. This leads to lower cutting temperatures, better chip control, and significantly longer tool life when working with non-ferrous metals. For CNC shops that demand "perfect parts, every time," the SPGG07 is the trusted industry standard.

— Production Lead (USA)Hervorragende Oberfläche bei Aluminium-Guss. Sehr scharfe Kante.
— CNC Spezialist (Germany)Ottimo grado K10. Zero incollamento del materiale.
— Meccanica Generale (Italy)Sharpest edge we've used in the shop. Great for plastics too.
— Tooling Tech (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.
