Osg 402-0781 Square End Mill 5/64 in 2 Flute Solid Carbide

Product Description

The OSG 402-0781 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. Built from micrograin solid carbide, it delivers the rigidity and edge retention required for cutting ferrous and non-ferrous materials at tight tolerances. The 2-flute configuration provides efficient chip evacuation in slotting and light profiling work. With a 30-degree helix angle and right-hand spiral flute geometry, this end mill produces smooth cuts with consistent finish quality. Centercutting capability allows direct plunge entry without a pre-drilled hole. This tool is sized for small-feature work, fitting CNC machining centers, knee mills, and manual machines equipped with 1/8 inch collets.

This end mill is suited for detailed milling passes on small components where tight dimensional control is required. The 5/64 inch diameter and 1/4 inch length of cut make it well-matched for slot milling, profiling, and finishing passes in dies, molds, fixtures, and precision parts. The regular-length body keeps deflection low in shallow-depth applications. Machinists and tool-and-die makers working with aluminum, brass, steel, and similar materials in job shop and production environments will find this tool appropriate for fine-feature work.

Key Features

• Micrograin solid carbide construction for superior hardness and wear resistance
• 2-flute design promotes chip clearing in slot and contour milling
• 30-degree helix angle for smooth cutting action and reduced cutting forces
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute for standard spindle rotation
• Uncoated finish suitable for general-purpose milling across common workpiece materials

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with 1/8 inch collets or toolholders. Part of the OSG Series 402 end mill line.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer guidelines. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the shank fully and evenly in a clean, undamaged collet to the recommended grip depth before torquing. Confirm runout within acceptable limits before commencing a cut.
