Osg 402-156211 Square End Mill 5/32 Inch Solid Carbide

Product Description

The OSG 402-156211 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. It features a 5/32-inch cutting diameter, a 9/16-inch length of cut, and a 30-degree helix angle with a TiAlN finish for extended tool life in ferrous and nonferrous materials. The micrograin carbide substrate provides hardness and wear resistance suited to high-speed cutting operations. This is a centercutting, right-hand cut, right-hand flute tool in a spiral flute configuration, making it effective for both plunge entry and peripheral milling. Machinists and CNC operators working in job shops, toolrooms, and production environments are the primary users of this tool.

This end mill fits standard milling machines and CNC machining centers where a 3/16-inch shank diameter is compatible with the collet or tool holder in use. The regular-length design and 2-inch overall length suit close-tolerance work in slots, pockets, and contour cuts on steel, stainless, aluminum, and similar workpiece materials. The 2-flute geometry provides improved chip evacuation in softer materials and slotting operations where chip clearance is critical.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• TiAlN coating extends tool life in dry and semi-dry cutting conditions
• 30-degree helix angle improves cutting action and surface finish
• Centercutting design allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute configuration for standard spindle operation
• 2-flute geometry maximizes chip clearance in slotting and softer materials

Compatibility

Designed for use in milling machines and CNC machining centers accepting a 3/16-inch shank diameter via ER collet, end mill holder, or equivalent tooling system.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with speeds, feeds, and tool runout requirements for carbide end mills. Ensure the spindle and tool holder are clean and free of chips before seating the shank. Confirm proper collet size and torque the retention mechanism to the tool holder manufacturer specification before engaging the spindle. Inspect the cutting edges for chipping before each use and replace if damage is visible.
