Osg 462-3750 Square End Mill 0.375 in 2 Flute Solid Carbide

Product Description

The OSG 462-3750 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 0.375-inch cutting diameter, a 1.125-inch length of cut, and a 3-inch overall length, making it suited to long-reach profiling and slotting tasks. The 2-flute geometry paired with a 30-degree helix angle promotes efficient chip evacuation, especially in softer metals and non-ferrous materials. Manufactured from micrograin solid carbide, this uncoated end mill offers consistent dimensional accuracy and edge integrity across production and job-shop environments. It is installed and operated by machinists and CNC programmers.

This end mill fits standard milling machines, CNC machining centers, and manual mills equipped with collets or end mill holders accepting a 0.375-inch shank. The long series designation and 1.125-inch length of cut allow access to deeper features and stepped profiles that shorter end mills cannot reach. It is commonly applied to slotting, profiling, and peripheral milling in aluminum, brass, plastics, and mild steels. The Series 462 designation identifies it within the OSG catalog for direct reorder and cross-referencing.

Key Features

• Micrograin solid carbide construction for high edge strength and wear resistance
• 2-flute design with 30-degree right-hand spiral helix for effective chip removal
• Centercutting geometry allows direct plunge entry without a pilot hole
• Right-hand cut and right-hand flute for use with standard spindle rotation
• Long series length of cut (1.125 inches) for deeper feature access
• Uncoated finish suitable for general-purpose and non-ferrous machining

Compatibility

Designed as a direct-fit replacement or standard selection for milling setups requiring a 0.375-inch shank end mill with a 0.375-inch cutting diameter and long series reach in the OSG Series 462 line.

Installation Notes

Installation is performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Use a properly sized collet or end mill holder rated for 0.375-inch shank tooling and torque the retention mechanism per the tool holder manufacturer specifications. Confirm correct spindle rotation direction (right-hand) before initiating a cut.
