Osg 3056210 Ball End Mill 1mm 2 Flute Solid Carbide

Product Description

The OSG 3056210 is a 2-flute solid carbide ball end mill designed for high-precision finishing operations in hard materials and hardened steels. It features a 1.00mm mill diameter with a 0.50mm nose radius, a 30-degree medium helix angle, and an extended long-neck geometry with a 9.90mm neck length and 0.95mm neck diameter. The DUROREY PVD coating provides wear resistance suited to demanding cutting conditions. With a 4.00mm straight-cylindrical shank and 45.00mm overall length, this end mill is used in CNC machining centers running tight-tolerance finishing passes where reach into deep cavities or restricted geometries is required.

This tool is intended for use in precision CNC milling applications where standard-reach tooling cannot access deep pockets, narrow slots, or contoured cavity walls. Primary workpiece materials are hard materials and hardened steels. The long-neck, extended-reach design allows the tool to maintain rigidity while reaching features that shorter tools cannot access. It is a single-end tool with right-hand cutting and right-hand flute direction. The Series 8590 designation places it within OSG's high-hardness finishing line.

Key Features

• 1.00mm mill diameter with 0.50mm ball nose radius for fine finishing in hard steels
• Extended long-neck geometry: 9.90mm neck length and 0.95mm neck diameter for deep-cavity reach
• DUROREY PVD coating for wear resistance in high-hardness workpiece materials
• Solid carbide construction with 30-degree medium helix and helical flute type
• Right-hand cut, right-hand flute, single-end configuration
• Mill diameter tolerance of plus or minus 0.005mm for tight-tolerance finishing

Compatibility

Designed as an OEM-style precision cutting tool for CNC machining centers accepting a 4.00mm straight-cylindrical shank. Suited for hard material and steel workpiece applications as specified by OSG Series 8590.

Installation Notes

Installation and tool changes should be performed by qualified machinists or CNC operators following machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool from the holder. Use an appropriate collet or tool holder rated for 4.00mm shank diameter to maintain concentricity and minimize runout. Verify tool projection and neck clearance against the workpiece geometry before running the program.
