N123G2-0300-0002-GF 1125 Sandvik Coromant Indexable Insert Carbide Inserts Long Life

The N123G2-0300-0002-GF 1125 is a premium indexable insert from Sandvik Coromant, engineered for high-precision turning and profiling operations in demanding industrial environments. As a flagship product in Sandvik's cutting tool lineup, this insert integrates advanced material science, precision manufacturing, and innovative geometry to deliver exceptional performance, tool life, and cost efficiency. Designed for machining a wide range of materials—including carbon steel, alloy steel, stainless steel, and cast iron—it is the ideal choice for automotive, aerospace, general engineering, and precision component manufacturing industries.

• Features Sandvik GC1125 carbide substrate with exceptional hardness, wear resistance, and toughness, capable of withstanding high cutting temperatures and forces, minimizing insert chipping.
• Innovative TiCN-Al2O3-TiN multilayer coating: outer TiN reduces friction, middle Al2O3 ensures high-temperature stability, inner TiCN enhances coating adhesion, extending tool life by 30%-50% compared to standard coated inserts.
• Smooth coating surface enables efficient chip evacuation, reducing built-up edge (BUE) and ensuring superior workpiece surface finish.

• Triangular shape with 3 cutting edges maximizes insert utilization and reduces per-part processing costs.
• 0.02 mm small corner radius is ideal for high-precision profiling and thin-walled component machining, preventing workpiece surface scratches.
• Optimized rake angle and edge preparation minimize cutting forces and vibration, enhancing machining stability—perfect for high-precision processing of critical components.

• Compatible with machining of carbon steel, alloy steel, stainless steel, cast iron, and other materials, meeting complex processing needs across multiple industries.
• Suitable for finishing, semi-finishing, and profiling operations, compatible with turning centers, CNC lathes, and other machining equipment.
• Compatible with high cutting speeds and feeds, improving production efficiency while maintaining processing quality, reducing unit time costs.

• Complies with ISO standards and Sandvik's strict quality control system—each insert undergoes precision inspection to ensure dimensional accuracy and performance consistency.
• Backed by Sandvik's century-old technical expertise and global service network, providing professional technical consultation and application solutions.

• Automotive Manufacturing: Turning of precision components such as engine crankshafts, camshafts, and transmission gears.
• Aerospace: Semi-finishing and finishing of aluminum alloy and titanium alloy structural parts.
• General Engineering: Batch processing of gears, shafts, and sleeves.
• Mold Making: Profiling of mold cavities and cores.
• Medical Devices: High-precision cutting of stainless steel and titanium alloy medical components.

1. Ensure the tool holder is compatible with the insert (recommended Sandvik CoroTurn 107/200 series holders). Clean the contact surfaces of the holder and insert during installation to avoid positioning errors caused by impurities.
2. Recommended cutting parameters: Cutting speed (vc) = 100-300 m/min, Feed rate (f) = 0.05-0.2 mm/rev, Depth of cut (ap) = 0.1-2 mm (adjust based on workpiece material and machine performance).
3. Regularly inspect the cutting edge wear. Rotate or replace the insert when wear reaches 0.2-0.3 mm to maintain processing quality.
4. Use cutting fluid for machining sticky materials (e.g., stainless steel) to improve chip evacuation and extend tool life.

• Packaging: 10 inserts/box, moisture-proof and anti-static packaging to ensure product integrity during transportation.
• Warranty: 12-month warranty under normal usage conditions. Return or exchange is available with purchase proof for quality issues.
• Technical Support: Professional services including cutting parameter optimization and processing solution customization. A global rapid response team is available to resolve usage-related issues.
