Osg 3182439 Square End Mill 0.1535 in 2 Flute Solid Carbide

Product Description

The OSG 3182439 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 0.1535-inch cutting diameter and a 35-degree helix angle, this tool delivers smooth chip evacuation and reduced cutting forces in both roughing and finishing passes. The WXL coating provides enhanced wear resistance and lubricity at the cutting edge. At 2 flutes, it is suited for applications where chip clearance is a priority, such as slotting and profiling in tight geometries. This end mill is installed by machinists and tool-and-die professionals on CNC machining centers and manual mills.

This end mill fits applications requiring a small-diameter, high-precision tool in a 6.00-millimeter shank configuration. The 0.4606-inch length of cut allows for moderate-depth slotting and contour milling. The right-hand cut and right-hand flute direction make it compatible with standard spindle rotation on conventional machining equipment. Typical use cases include mold and die work, prototype machining, and finish profiling of small features. It is centercutting, allowing direct plunge entry without a pre-drilled start hole.

Key Features

• 0.1535-inch cutting diameter with 0.4606-inch length of cut for small-feature milling
• Solid carbide micrograin substrate for rigidity and edge retention
• WXL coating for improved wear resistance and reduced friction at the cutting edge
• 35-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Centercutting geometry allows direct plunge entry
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual milling machines accepting a 0.2362-inch (6.00 mm) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or tool crib technician. Ensure the spindle is fully powered down and the machine is in a safe lockout state before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention hardware per the machine tool manufacturer's specification. Inspect the cutting edges under magnification before use to confirm no chipping or coating damage occurred during handling.
