Osg 414-375011 Square End Mill 3/8 in 4 Flute Solid Carbide

Product Description

The OSG 414-375011 is a solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It measures 0.375 inches in diameter with a 0.625-inch length of cut and a 2.0-inch overall length. The 4-flute, 30-degree helix spiral geometry promotes efficient chip evacuation and surface finish quality. A TiAlN coating increases heat resistance and tool life in elevated-temperature cutting environments. The micrograin carbide substrate provides rigidity and edge retention suited to production machining operations. This tool is installed by machinists and CNC programmers in job shop, tool room, and production environments.

This end mill is suited for slotting, profiling, and peripheral milling in stub-length applications where rigidity is a priority over reach. The 3/8-inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting without reduction. Right-hand cut and right-hand flute orientation are standard for conventional vertical machining center spindles. Centercutting capability allows plunge entry without a pre-drilled hole, supporting ramp and helical interpolation strategies.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• TiAlN finish for elevated heat resistance in dry or semi-dry cutting
• 4-flute, 30-degree helix spiral design for balanced chip evacuation and finish
• Centercutting geometry supports plunge, ramp, and helical entry
• Right-hand cut, right-hand flute — compatible with standard CNC spindle rotation
• Stub length type provides maximum rigidity in short-reach applications

Compatibility

Designed for use in standard 3/8-inch collets, end mill holders, or shrink-fit tooling systems on vertical and horizontal machining centers. Part of OSG Series 414.

Installation Notes

Installation requires a properly sized collet or end mill holder rated for the 3/8-inch shank diameter. Ensure the machine spindle is fully stopped and the tool is secured to the recommended gauge length before engaging the workpiece. Follow shop-standard runout inspection procedures after tool mounting. Handle carbide tooling carefully to avoid chipping the cutting edges during loading and storage.
