Osg 3042003 Ball End Mill 0.0787 in 2 Flute Solid Carbide

Product Description

The OSG 3042003 is a 2-flute solid carbide ball end mill engineered for high-precision finishing operations in hard materials and hardened steels. The tool features a 2.00 mm (0.0787 inch) mill diameter with a 1.00 mm nose radius, a 6.00 mm straight-cylindrical shank, and a 50.00 mm overall length. It carries OSG DUROREY PVD coating, which provides thermal resistance and surface hardness suited to aggressive cutting conditions in hard workpiece materials. The extended-reach geometry with a 12.00 mm reach length and a 1.95 mm neck diameter allows the tool to access deep or restricted features without sacrificing rigidity. Machinists and toolroom operators working in die and mold, aerospace, and precision component manufacturing will find this tool well matched to finishing passes on hardened steel.

The OSG 3042003 is designed for use in hard materials (material code H) as the primary application, with steel (material code P) as the secondary workpiece material. The extended-reach design and small 2.00 mm cutting diameter make it suitable for fine-detail work in cavities, contoured surfaces, and tight-tolerance features on CNC machining centers. The 25-degree medium helix angle supports chip evacuation during both roughing and finishing passes. A 1.60 mm length of cut and helical flute geometry allow smooth entry and consistent surface finish on hardened workpieces.

Key Features

• DUROREY PVD coating for elevated hardness and thermal resistance in hard material cutting
• 2.00 mm ball diameter with 1.00 mm nose radius for fine-detail and contour finishing
• Extended-reach design: 12.00 mm reach length with 1.95 mm neck diameter for deep-cavity access
• Right-hand cut, right-hand helical flutes at 25-degree medium helix angle
• Solid carbide substrate for rigidity and wear resistance at elevated cutting speeds
• Single-end construction; Series 8510 for consistent dimensional tolerances (mill diameter tolerance: 0.005 mm)

Compatibility

Designed for use in CNC machining centers and high-speed milling spindles accepting a 6.00 mm straight-cylindrical shank. Primary workpiece materials are hard materials and hardened steels. Part of the OSG Series 8510 high-precision finishing end mill line.

Installation Notes

Installation and tool changes should be performed with the spindle fully stopped and the machine control in a safe state. Use a properly sized collet or end mill holder rated for the 6.00 mm shank diameter to ensure secure clamping and runout control. Verify tool projection and reach clearance before initiating the cut cycle, particularly when working in deep cavities. Follow the machine tool manufacturer guidelines and the cutting tool data sheet for recommended speeds and feeds appropriate to workpiece hardness.
