GLG Spain Extreme Co5 315mm Precut

The GLG Extreme Cobalt Co5 is a high-performance high-speed steel (HSS) circular blade designed for demanding industrial cutting—and an excellent premium material for gaff knives (tari) requiring superior heat resistance and edge stability.

Manufactured using Cobalt-enriched HSS (Co5 / M35 equivalent), this material contains approximately 5% cobalt, enhancing red hardness, wear resistance, and structural stability at elevated temperatures. The addition of cobalt improves the steel’s ability to maintain hardness even under intense friction, making it ideal for high-speed and high-stress cutting applications.

GLG’s EXTREME series further elevates performance through precision grinding and advanced surface treatment, resulting in smoother cutting action, longer blade life, and consistent performance across demanding conditions.

🔥 Why Co5 (Cobalt HSS) for Gaff Knives (Tari)?

• Superior heat resistance – maintains hardness even under extreme friction
• Enhanced edge retention – stays sharper longer than standard HSS
• Improved wear resistance – withstands repeated impact and use
• Higher red hardness – ideal for high-speed and aggressive applications
• Stable microstructure – consistent performance and reliability

Compared to standard DMo5 (M2), Co5 offers better heat performance and longer edge life, making it a preferred upgrade for users seeking stronger, longer-lasting gaff knives.

⚙️ Ideal for:

• High-performance gaff knives (tari)
• Competitive and professional use
• Applications requiring extended edge life and heat resistance

This is a Julia Evolution high-speed steel (HSS) circular saw blade — flat ground, no hub, and with a 25.4 mm center hole — sold as a whole uncut disc with no teeth. Manufactured with uniform thickness across the entire blade, it’s perfect for laser or waterjet precutting into gaff knife blanks.

Originally built for industrial cutting, Julia Evolution blades are made from:

• High-grade HSS with ultra-fine grain
• Multilayer PVD coating with surface hardness above 3,400 HV

• Exceptional wear resistance, toughness, and thermal stability

This makes it an ideal raw material for custom tari/gaff knives, ensuring:

• Consistent performance during shaping and grinding

• Reliable flatness and even hardness

• Compatibility with CNC, laser, or waterjet processes

Specifications:

• Material: Julia Evolution HSS

• Format: Flat ground, no hub, no teeth

• Center Hole: 25.4 mm (1”)

• Thickness: Uniform across the entire blade

• Use: For precutting into gaff knives via laser or waterjet

Note: This is a whole blade (not yet precut). Shaping service via laser or waterjet cutting is available upon request.

The STARK Blackface Co5 Precut is a high-performance precut made from HSS Cobalt 5% , designed for extreme wear resistance and edge retention. The BLUE coating helps reduce friction during processing, while the waterjet cutting process ensures the steel’s original hardness and grain structure remain intact. This precut is engineered for precision — ideal for crafting tough, high-grade tari blades, and is ready for garol brazing and final edge grinding.

The Kinkelder Solar TiN Gold is a high-speed steel (HSS) blade engineered for precision and strength.
