Osg 402-234411 Square End Mill 15/64 in 2 Flute Carbide

Product Description

The OSG 402-234411 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. Built from micrograin carbide stock and finished with a TiAlN coating, this tool delivers extended tool life and heat resistance in ferrous and non-ferrous materials. The 2-flute, 30-degree helix spiral geometry promotes efficient chip evacuation and smooth cutting action. With a 15/64-inch cutting diameter and a 3/4-inch length of cut, it handles slotting, profiling, and peripheral milling operations in a compact, regular-length profile. The 1/4-inch shank fits standard collets and tool holders common to CNC mills and manual knee mills alike.

This end mill is suited for job shops, tool rooms, and production environments where tight-tolerance features are required in steel, aluminum, stainless, and similar workpiece materials. The centercutting geometry allows direct plunge entry into the workpiece, expanding its use across ramping, helical interpolation, and full-slot entry cuts. Right-hand cut and right-hand flute orientation match standard spindle rotation on conventional machining centers. The Series 402 designation places it within OSG's catalog of general-purpose carbide end mills.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiAlN finish increases surface hardness and thermal resistance during high-speed cuts
• 30-degree helix spiral flute promotes efficient chip evacuation and reduces heat buildup
• Centercutting design allows direct plunge, ramp, and helical entry
• Right-hand cut, right-hand flute — compatible with standard CNC and manual mill spindles
• Regular length profile suits general-purpose slotting and profiling without added deflection risk

Compatibility

Designed as a general-purpose solid carbide square end mill for use in standard 1/4-inch collets, ER collet chucks, and end mill holders on CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by machining professionals familiar with toolholder torque procedures and collet runout specifications. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Verify collet bore size matches the 1/4-inch shank before seating the tool. Consult the machine manufacturer and applicable shop safety standards when setting cutting parameters for new tooling.
