Osg 84100223 Ball End Mill 0.0938 in 2 Flute Solid Carbide

Product Description

The OSG 84100223 is a 2-flute solid carbide ball end mill designed for high-precision finishing in hard materials and steels. It carries a 0.0938 inch mill diameter with a 0.075 inch reach length and a 0.25 inch straight-cylindrical shank. The DUROREY PVD coating provides wear resistance and thermal protection during aggressive cutting cycles. The stub-length geometry keeps the tool rigid at tight overhangs, reducing deflection when working close tolerances. This tool is suited for CNC machining centers and is installed by machinists and tooling technicians operating in precision metalworking environments.

This end mill is built for cutting hard materials, with a primary workpiece material classification of hard material and a secondary classification of steel. The low, right-hand helical flute design moves chips efficiently while maintaining a clean cutting edge on high-hardness workpieces. The stub length and short 0.075 inch length of cut make it appropriate for finishing passes and detail work in die, mold, and precision component machining. It is a single-end tool from OSG Series 8410.

Key Features

• DUROREY PVD coating for improved wear resistance in hard and steel materials
• Solid carbide construction provides rigidity and edge retention at small diameters
• 2-flute, right-hand helical geometry for efficient chip evacuation
• Stub-length design minimizes deflection for high-precision finishing passes
• Ball nose profile with 0.0469 inch nose radius for contour and 3D surface work
• Straight-cylindrical shank compatible with standard ER and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-application solid carbide ball end mill for CNC machining operations involving hard materials and steel. Part of the OSG Series 8410 high-precision finishing line.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. The machine spindle must be fully stopped and the tool changer disabled before changing tooling. Use a calibrated torque wrench and the appropriate collet or end mill holder to seat the 0.25 inch shank securely. Verify runout with a dial indicator before beginning a cutting program, as runout at small diameters significantly affects tool life and surface finish.
