Osg 404-375005 Square End Mill 3/8 in 4 Flute Carbide Tin

Product Description

The OSG 404-375005 is a solid carbide square end mill designed for precision material removal in professional machining applications. Built from micrograin carbide and coated with TiN (Titanium Nitride), it delivers extended tool life and reduced friction at the cutting edge. The 4-flute, single-end configuration provides excellent surface finish and chip evacuation across a wide range of workpiece materials. With a 3/8 inch mill diameter, a 1 inch length of cut, and a 2.5 inch overall length, this end mill fits standard tool holders and suits general-purpose CNC milling and manual mill operations in job shops and production environments.

This end mill is suited for milling steel, stainless steel, cast iron, aluminum and other non-ferrous metals, and hardened materials. The 30-degree right-hand helix and right-hand cutting direction make it a reliable choice for conventional and climb milling passes. Center-cutting capability allows for direct plunge entry where the operation requires it, adding versatility for pocketing and slotting work in both residential toolroom and industrial production contexts.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiN coating reduces friction and extends tool life on ferrous and non-ferrous materials
• 4-flute design improves surface finish and increases feed rates versus 2-flute alternatives
• 30-degree right-hand spiral helix promotes efficient chip evacuation
• Center-cutting geometry permits direct plunge entry for pocketing and slotting
• Single-end configuration with 3/8 inch shank fits standard collets and end mill holders

Compatibility

Designed for use in standard 3/8 inch collets and end mill holders on CNC machining centers and manual vertical mills. Primary workpiece materials include steel, stainless steel, cast iron, aluminum and non-ferrous alloys, and hardened materials.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle at a full stop and machine power isolated. Seat the shank fully into the collet or end mill holder and torque the retention hardware per the machine manufacturer specification. Confirm runout with a dial indicator before beginning the cut. Follow applicable shop safety procedures and machine guarding requirements during operation.
