Osg 414-0312-BN Ball End Mill 0.0313 in 4 Flute Carbide

Product Description

The OSG 414-0312-BN is a solid carbide ball end mill built for precision milling in demanding production environments. With a 0.0313-inch (1/32 inch) mill diameter and a 4-flute helical design, this tool is engineered for both roughing and finishing operations in a single setup. The 30-degree helix angle and micrograin carbide construction provide rigidity and edge retention when cutting ferrous and non-ferrous materials. The bright, uncoated finish suits applications where coating buildup or heat is not a primary concern. Machinists and toolroom professionals reach for this series when tight tolerances and repeatable results are required on small-feature work.

This end mill is suited for use on CNC machining centers and manual mills handling small-diameter, close-tolerance cuts. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The standard-length geometry and straight cylindrical shank make it compatible with collets and end mill holders accepting a 1/8-inch shank. It performs in both roughing and finishing passes without a tool change, reducing cycle time on intricate part geometries.

Key Features

• Solid micrograin carbide construction for edge retention and dimensional stability
• 4-flute helical design supports both roughing and finishing in one tool
• 30-degree medium helix angle balances chip evacuation and cutting forces
• Bright uncoated finish suitable for a wide range of workpiece materials
• Single-end configuration with a straight cylindrical 1/8-inch shank
• Nose radius of 0.0157 inches produces consistent ball-end profiles on finished surfaces

Compatibility

Designed for use with standard collet chucks and end mill holders accepting a 0.1250-inch straight cylindrical shank. Compatible workpiece materials 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 a machinist or toolroom technician using a properly sized collet or end mill holder. Confirm the spindle and holder are clean and free of debris before seating the shank to full depth. Power down and lock out the machine before changing tooling in accordance with shop safety procedures. Verify runout with a dial indicator after clamping to ensure the small diameter is held within tolerance before beginning the cut.
