Osg 412-1875-BN Ball End Mill 0.1875 in 2 Flute Carbide

Product Description

The OSG 412-1875-BN is a solid carbide ball end mill from the OSG Series 412BN lineup, designed for precision milling of curved surfaces, contours, and 3D profiles. It features a 0.1875-inch (3/16-inch) mill diameter and a 0.375-inch length of cut, with a 30-degree helix angle and a helical flute geometry that supports both roughing and finishing operations. The micrograin carbide construction delivers consistent edge integrity under demanding cutting conditions. This tool ships in a bright, uncoated finish and is configured as a single-end mill with a straight-cylindrical shank.

This end mill is suited for shops and machining operations requiring tight-tolerance contouring on a range of workpiece materials. Rated secondary workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The 2-inch overall length and standard length classification make it a practical choice for general CNC milling setups where reach is not a limiting factor. It is commonly used in job shop, tool room, and production environments requiring precise ball-nose profiling at small diameters.

Key Features

• Solid micrograin carbide construction for consistent tolerancing and edge stability
• Ball nose geometry for 3D contouring, radii, and profiled surface cuts
• 30-degree medium helix angle supports chip evacuation in both roughing and finishing passes
• Bright, uncoated finish suitable for a broad range of workpiece materials including superalloys and titanium
• Right-hand cutting and right-hand flute direction; single-end configuration
• Mill diameter tolerance of +0.0000 / -0.0020 inches and shank diameter tolerance of +0.0000 / -0.0005 inches

Compatibility

Designed as a direct-application solid carbide ball end mill for CNC machining centers and manual mills accepting a 0.1875-inch straight-cylindrical shank. Compatible workpiece material categories include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials as designated by material codes P, M, K, N, S, and H.

Installation Notes

Installation is performed by machinists using a compatible collet or end mill holder sized for a 0.1875-inch straight shank. Confirm runout and clamping torque specifications per the toolholder manufacturer's guidelines before cutting. Ensure the spindle is fully stopped and the machine is in a safe state before inserting or removing the tool. Do not use this tool beyond its rated length of cut or in applications requiring coolant-through delivery, as this series does not support coolant-through capability.
