Osg 414-7500-BN11 Ball End Mill 0.75in 4 Flute Tialn Carbide

Product Description

The OSG 414-7500-BN11 is a solid carbide ball end mill designed for precision milling operations in metalworking and machining applications. With a 0.75 inch diameter and a 1 inch length of cut, this single-end tool features four flutes and a 30-degree right-hand helix for efficient chip evacuation and smooth surface finishes. The micrograin carbide substrate provides rigidity and wear resistance, while the TiAlN coating extends tool life when cutting ferrous and hardened materials at elevated temperatures. Machinists and toolroom operators working on CNC mills and machining centers will find this tool suitable for profiling, contouring, and finishing passes.

This end mill is built for applications requiring accurate ball-nose geometry, including 3D contouring, die and mold work, and curved surface finishing. Its stub-length configuration keeps deflection low during aggressive cuts. The 0.75 inch shank diameter matches the cutter diameter for straightforward toolholder compatibility in standard ER, side-lock, or shrink-fit holders. It is well suited for use on steel, stainless steel, cast iron, and other ferrous alloys where TiAlN coating performance is maximized.

Key Features

• 0.75 inch ball nose diameter for accurate radius profiling and 3D contouring
• 4-flute, right-hand spiral design promotes efficient chip removal and improved surface finish
• TiAlN coating provides high heat resistance and extended tool life in ferrous materials
• Micrograin solid carbide substrate delivers rigidity and edge retention
• 30-degree helix angle balances cutting forces and reduces chatter
• Stub-length (Series 414BN) design minimizes deflection in tight-clearance setups

Compatibility

Designed as an OEM-style replacement and direct-fit tool for standard 0.75 inch diameter toolholders including ER collet chucks, side-lock holders, and shrink-fit systems used in CNC vertical and horizontal machining centers.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and locked out before changing tooling. Confirm the shank is fully seated to the recommended insertion depth in the holder and that the collet nut or set screw is torqued per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning cuts to protect both the tool and the workpiece.
