Osg 462-7874 Square End Mill 0.7874 in 2 Flute Solid Carbide

Product Description

The OSG 462-7874 is a solid carbide square end mill engineered for precision milling in demanding metalworking and machining applications. With a 0.7874 inch (20 mm) cutting diameter and a 2.2441 inch length of cut, this long-series end mill delivers extended reach for deeper pocketing and slotting operations where standard-length tools fall short. The two-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation, reducing heat buildup during cuts. Manufactured from micrograin carbide in a bright, uncoated finish, this tool is suited for machinists, tool-and-die makers, and CNC operators running production or prototype work.

The OSG 462-7874 belongs to the Series 462 long-length program and is intended for milling operations in ferrous and non-ferrous materials where depth of cut exceeds what a standard-reach tool can reach. The centercutting geometry allows plunge entry, making it versatile for pocketing, slotting, and peripheral milling in vertical and horizontal machining centers. Its 0.7874 inch shank diameter matches the cutting diameter, enabling direct chuck or collet holding without adapters in most standard toolholding systems.

Key Features

• 0.7874 inch (20 mm) cutting diameter with matching 0.7874 inch shank diameter
• 2.2441 inch length of cut for deep pocketing and extended-reach operations
• 2-flute right-hand spiral with 30-degree helix for effective chip removal
• Centercutting design supports direct plunge entry
• Micrograin solid carbide construction for wear resistance and edge retention
• Bright, uncoated finish — no coating buildup to affect tolerances
• Long-series length type for applications beyond standard reach

Compatibility

Designed as an OEM-style replacement and standard production end mill in the OSG Series 462 long-length program, suitable for use in CNC machining centers and manual mills with standard collet or chuck toolholding sized for a 0.7874 inch shank.

Installation Notes

Installation and tool changes should be performed with the machine fully powered down and the spindle confirmed stationary. Secure the shank fully within the collet or chuck to the recommended grip depth for the toolholder in use, following the toolholder manufacturer guidelines. Inspect the cutting edges for chips or damage before mounting. Follow applicable shop safety protocols and machine manufacturer specifications for spindle speed and feed rates.
