R245-12T3E-W 1030 Sandvik Milling Inserts Steel Machining Coated Inserts

The Sandvik R245-12T3E-W 1030 insert is a high-performance carbide indexable cutting tool engineered for precision metal turning. Integrating Sandvik’s century-old cutting expertise with advanced material technology, it is designed for machining carbon steel, alloy steel, stainless steel, and cast iron. The optimized groove design and wear-resistant grade 1030 carbide ensure smooth chip evacuation, low cutting force, and extended tool life, making it an ideal choice for general machinery, automotive manufacturing, aerospace, and other industries to improve processing efficiency and reduce production costs.

1. Super Wear-Resistant Material: Adopts Sandvik-exclusive grade 1030 carbide with special wear-resistant additives, featuring a hardness of over HRA92 and excellent high-temperature resistance. The service life is 30%-50% longer than ordinary inserts, reducing tool change frequency.
2. Optimized Groove Design: E-type groove combined with W-type chip breaker enables smooth chip flow, preventing chip entanglement on workpieces or tools, reducing machining vibration, and ensuring cutting stability.
3. High-Precision Machining: 3.0mm nose radius (T3 specification) and ISO class M cutting edge precision deliver a surface roughness of Ra≤0.8μm, meeting strict requirements for semi-finishing and finishing operations.
4. Versatile Application: Compatible with carbon steel, alloy steel, stainless steel (austenitic/martensitic), and cast iron. Suitable for general turning, profile turning, and other processes, offering strong versatility.
5. Easy Installation: Standard indexable design, compatible with corresponding Sandvik tool holders, enabling quick and convenient installation and replacement, reducing operational complexity.

• Industries: General Machinery Manufacturing, Automotive Parts Processing (Engine Blocks, Crankshafts), Aerospace Components (Lightweight Alloy Structural Parts), Mold Making, Construction Machinery Accessories Production.
• Processing Scenarios: Semi-finishing/finishing of steel parts, low-load cutting of stainless steel, surface turning of cast iron, especially suitable for mass production with high requirements for machining precision and tool life.

1. Genuine Guarantee: 100% original Sandvik products, complying with international cutting tool standards, free from counterfeits.
2. Technical Support: Backed by Sandvik’s global cutting technology system, providing professional cutting parameter optimization advice.
3. Cost-Effectiveness: Extended service life reduces per-workpiece tool costs, while high-efficiency cutting boosts productivity, delivering significant comprehensive benefits.
4. Sufficient Inventory: Spot supply, supporting bulk purchases and customized needs with short delivery cycles.

1. Ensure tight fit between the insert and tool holder during installation, with uniform screw torque to avoid vibration affecting machining precision.
2. Recommended Cutting Parameters (Reference): Cutting speed v_c=100-250m/min, feed rate f=0.1-0.3mm/r, depth of cut a_p=0.1-2.0mm (adjust according to workpiece material and machine performance).
3. Regularly inspect cutting edge wear, and index or replace the insert in a timely manner to prevent chipping and ensure processing quality.
