Osg 484-375011 Square End Mill 3/8 in 4-flute Solid Carbide

Product Description

The OSG 484-375011 is a 4-flute solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide with a TiAlN coating, it delivers hardness and heat resistance suited to ferrous and non-ferrous materials at elevated cutting speeds. The 0.375-inch cutting diameter, 1.75-inch length of cut, and 30-degree helix angle combine to produce clean, efficient chip evacuation in slotting, profiling, and peripheral milling. The extra-long 4-inch overall length provides reach in deeper setups without sacrificing rigidity. This tool is installed by machinists, toolroom technicians, and CNC operators in production and job-shop environments.

The 484-375011 fits standard CNC machining centers, vertical mills, and manual milling machines accepting a 0.375-inch shank. The centercutting geometry allows direct plunge entry into workpiece material, making it suitable for pocket milling as well as conventional profiling passes. Its right-hand cut and right-hand spiral flute configuration follow standard spindle rotation conventions. The Series 484 extra-long length type is appropriate when standard-length tools cannot reach the required depth of cut in stepped or deep-pocket features.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• TiAlN finish for thermal protection at higher cutting speeds
• 4-flute spiral geometry with 30-degree helix angle for efficient chip evacuation
• Centercutting design enables direct plunge milling
• Extra-long 4-inch OAL for deep-reach applications
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style replacement or direct-use cutting tool for milling machines and CNC machining centers that accept a 0.375-inch round shank end mill with standard ER or side-lock toolholding systems.

Installation Notes

Installation is performed by qualified machinists or CNC toolroom personnel. The shank must be fully seated in a compatible toolholder and secured per the toolholder manufacturer torque specifications before spindle operation. Inspect the cutting edges for chips or damage before each use. Do not exceed the tool's rated depth-of-cut parameters for the workpiece material being machined.
