Osg 414-5000-BN Ball End Mill 0.5in 4 Flute Solid Carbide

Product Description

The OSG 414-5000-BN is a 4-flute solid carbide ball end mill designed for both roughing and finishing operations in a wide range of metalworking applications. Built on a micrograin carbide substrate, it carries a 0.5-inch mill diameter, a 0.625-inch length of cut, and a 30-degree right-hand helix. The straight cylindrical shank measures 0.5 inches in diameter and the overall length is 2.5 inches. The bright uncoated finish suits general-purpose cutting where coating is not required. This end mill is part of OSG Series 414BN, engineered to consistent tolerances for predictable tool life and repeatability on production setups.

The 414-5000-BN is suited for milling operations on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It fits standard machining centers and CNC mills wherever a 1/2-inch shank toolholder is used. The single-end design and standard length make it a practical choice for contour milling, profiling, slotting, and 3D surface work where a ball nose profile is required. Machinists and tooling specialists in job shops and production environments will find it applicable across a broad material range without requiring a coated variant.

Key Features

• Micrograin solid carbide construction for consistent edge integrity and dimensional tolerance
• 4-flute configuration supports both roughing and finishing in a single tool
• 30-degree medium helix angle balances chip evacuation with cutting stability
• 0.25-inch nose radius enables true ball-end profiling and contour work
• Bright uncoated finish — compatible with most cutting fluids and general-purpose applications
• Right-hand cut and right-hand flute direction; no chipbreaker, no variable helix, no coolant-through

Compatibility

Designed for use in standard 1/2-inch straight-bore toolholders on CNC machining centers and manual mills. Rated for secondary workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO material codes P, M, K, N, S, H).

Installation Notes

Installation is performed by qualified machinists or tooling technicians. The machine spindle must be at a full stop and the toolholder must be clean and free of debris before seating the shank. Confirm runout with a dial indicator after seating to stay within tolerance for the application. Follow the machine tool manufacturer and OSG cutting data recommendations for speeds, feeds, and depth of cut — do not infer these values from this listing.
