Osg 414-375008 Square End Mill 3/8 Inch 4 Flute Solid Carbide

Product Description

The OSG 414-375008 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin carbide with a TiCN (Titanium Carbonitride) finish, this stub-length end mill delivers wear resistance and edge retention in ferrous and non-ferrous materials. It features a 3/8 inch cutting diameter, a 5/8 inch length of cut, and a 2 inch overall length. The 4-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. This tool is installed by machinists and toolroom professionals working with CNC mills and manual milling machines.

This end mill is suited for slotting, profiling, and peripheral milling in production and job-shop environments. The centercutting geometry allows plunge cutting without a pilot hole, making it versatile across a range of milling strategies. The 3/8 inch shank diameter fits standard ER collets, end mill holders, and milling chucks commonly found in CNC machining centers and knee mills. Its stub length classification provides added rigidity, which is well suited to applications where deflection control is critical.

Key Features

• Solid micrograin carbide construction for extended tool life and edge integrity
• TiCN coating enhances surface hardness and reduces friction during cutting
• 4-flute spiral design with 30-degree helix angle for balanced chip evacuation and finish quality
• Centercutting capable — supports direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute orientation for standard spindle compatibility
• Stub length configuration increases rigidity and reduces deflection in tight setups

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for milling applications requiring a 3/8 inch diameter, 3/8 inch shank, and stub-length reach in standard end mill holders and collet chucks.

Installation Notes

Installation is performed by qualified machinists. Ensure the spindle is fully stopped and the machine is powered down or in an E-stop state before changing tooling. Seat the shank fully into the holder and torque the retention mechanism per the holder manufacturer specification. Inspect the collet or chuck for wear before seating this tool, as shank runout directly affects surface finish and tool life.
