Osg 3056208 Ball End Mill 1mm 2 Flute Solid Carbide

Product Description

The OSG 3056208 is a 2-flute solid carbide ball end mill engineered for high-precision finishing of hard materials and high-hardness steels. It carries a 1.00 mm (0.0394 inches) mill diameter with a 0.50 mm nose radius and a DUROREY PVD coating applied to extend tool life in demanding cutting conditions. The extended-reach long neck design — with a 4.00 mm straight-cylindrical shank and 45.00 mm overall length — provides clearance for deep-cavity and fine-detail work that standard-length end mills cannot reach. A 30-degree medium helix angle promotes chip evacuation and stable cutting action. This tool is installed by machinists and tool-and-die professionals working in precision machining environments.

The OSG 3056208 is suited for finishing and light roughing passes in hard materials and steel alloys. Its extended neck geometry makes it well matched to mold and die work, micro-feature machining, and deep-slot finishing where tool-to-workpiece clearance is critical. The single-end configuration and right-hand cut and flute direction are standard for CNC vertical machining centers and high-speed spindle setups. The 8590 Series positions this tool for high-hardness steel applications where surface finish and dimensional accuracy are the primary objectives.

Key Features

• 1.00 mm mill diameter with 0.50 mm nose radius for fine-detail ball-end profiling
• DUROREY PVD coating for extended tool life in hard and high-hardness steel cutting
• Extended-reach long neck design with 0.95 mm neck diameter and 9.70 mm reach length for deep-cavity access
• 30-degree medium helix angle promotes chip flow and cutting stability
• Solid carbide construction delivers rigidity and wear resistance at small diameters
• Right-hand cut, right-hand helical flutes — compatible with standard CNC spindle rotation

Compatibility

Designed for use in CNC machining centers with straight-cylindrical collet or toolholder systems accepting a 4.00 mm shank diameter. Primary workpiece materials are hard materials and steel alloys. No coolant-through capability; external coolant or misting is required when cutting strategies demand it.

Installation Notes

This tool should be installed by qualified machinists using a precision collet or shrink-fit holder rated for the 4.00 mm shank diameter to minimize runout at this scale. Confirm tool projection and reach length in CAM setup before cutting to avoid holder-to-workpiece interference on deep-cavity passes. Power down and lock out the spindle before tool changes. At 1.00 mm diameter, excessive feed rates or interrupted cuts increase the risk of tool fracture — verify cutting parameters against the OSG Series 8590 application data for the target workpiece hardness.
