Osg 462-3125 Square End Mill 5/16 Inch 2 Flute Solid Carbide

Product Description

The OSG 462-3125 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 5/16 inch cutting diameter, a 1-1/8 inch length of cut, and a 3 inch overall length, placing it in the long series category. The two-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting performance. Manufactured from micrograin solid carbide, this end mill delivers consistent edge integrity and dimensional accuracy. It is centercutting, allowing it to plunge directly into workpiece material. The uncoated finish suits a range of general-purpose milling tasks where coating is not specified.

This end mill is suited for milling slots, pockets, profiles, and contours in ferrous and non-ferrous materials. The long series length of cut makes it well-suited for deeper slot milling and step milling operations where standard-length tools fall short. It is commonly used in manual mills, CNC machining centers, and vertical mills in job shops, toolrooms, and production environments. A right-hand cut and right-hand flute configuration is standard for conventional spindle setups.

Key Features

• Solid micrograin carbide construction for edge stability and wear resistance
• Two-flute spiral design with 30-degree helix for efficient chip removal
• Centercutting capability allows direct plunge entry into material
• Long series length of cut at 1-1/8 inches supports deeper milling passes
• Uncoated finish for general-purpose use across a variety of materials
• Right-hand cut and right-hand flute for standard spindle compatibility

Compatibility

Designed as an OEM-style general-purpose square end mill compatible with standard 5/16 inch collets, ER collet chucks, and end mill holders used in CNC and manual milling equipment.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully within the collet or tool holder to the recommended grip depth, and verify runout with a dial indicator before beginning cuts. Follow the machine manufacturer and tooling guidelines for appropriate feed rates and speeds for the workpiece material.
