OYYU SCGT Aluminum Carbide Inserts | SCGT09T3 & SCGT1204 H01 Mirror Polish
Product Overview: Which Carbide Insert is Best for High-Speed Aluminum Turning?
Are you seeking a high-efficiency CNC turning insert engineered specifically to eliminate aluminum edge build-up (BUE) and chip jamming during high-speed machining? The OYYU SCGT Carbide Insert Series (H01 Grade) provides an industrial-grade solution designed for aluminum alloys, copper, brass, and non-ferrous soft materials.
Manufactured with an ultra-fine sub-micron carbide substrate paired with an un-coated H01 mirror-polished rake face, these inserts feature an aggressive -AK chipbreaker geometry. This design delivers razor-sharp cutting edges, minimized cutting friction, swift chip evacuation, and superior surface finish values (Ra < 0.4 μm). Fully compliant with ISO 1832 and ANSI standard designations.
2. Core Advantages & Technical Features
Mirror Polish H01 Rake Face
Ultra-smooth polished surface reduces material adhesion, preventing Built-Up Edge (BUE) even under continuous dry or MQL cutting conditions.
AK Precision Chipbreaker
High positive rake design lowers cutting resistance and power consumption, directing long-curled aluminum swarf into controlled coils.
Sub-Micron Substrate
High-density K10-K20 un-coated carbide grain structure ensures sharp edge integrity without premature chipping during interrupted cuts.

Q: Can I use OYYU SCGT H01 inserts for stainless steel or carbon steel turning?
A: It is not recommended. The H01 grade is an un-coated grade designed specifically for non-ferrous metals. Steel machining generates high temperatures that cause rapid adhesive wear on un-coated carbide. For steels, use PVD/CVD-coated inserts like CCMT or TNMG with steel geometries.
Q: What is the difference between SCGT09T302, SCGT09T304, and SCGT09T308?
A: The difference lies in the corner nose radius (r):
• 02 (0.2mm / 0.008"): Super-fine finishing, reduced chatter on thin-walled parts.
• 04 (0.4mm / 0.016"): General-purpose turning balancing sharpness and edge strength.
• 08 (0.8mm / 0.031"): Roughing cuts, higher feed rates, and improved thermal durability.
Q: Should I run coolant when turning aluminum with SCGT H01 inserts?
A: High-pressure water-soluble coolant or MQL (Minimum Quantity Lubrication) is recommended. Coolant flushes soft swarf chips out of deep bores, prevents re-cutting, and ensures optimal surface roughness.
Machining Troubleshooting Guide & Tech Tips
Issue: Built-Up Edge (BUE) / Material Melting on Rake Face
Solution: Increase cutting speed (Vc), apply coolant/air blast, ensure insert is OYYU polished H01 grade.
Issue: Workpiece Vibration / Chatter Marks
Solution: Reduce corner radius (e.g., switch from 08 to 04 or 02), reduce depth of cut (ap), increase rigidity of setup.
