Osg 3182434 Square End Mill 0.1339 in 2 Flute Solid Carbide

Product Description

The OSG 3182434 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.1339-inch (3.40 mm) cutting diameter and a 0.4016-inch (10.20 mm) length of cut, this tool handles slotting, profiling, and peripheral milling in tight tolerances. The WXL finish coating improves wear resistance and tool life in ferrous and non-ferrous materials. A 35-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Two flutes keep the geometry open for efficient material removal at small diameters. This end mill is installed by machinists and CNC operators working in tool-and-die, aerospace, and general precision machining environments.

This end mill is suited for light to medium milling passes in small-bore and fine-feature work where a sub-0.140-inch diameter tool is required. The centercutting design allows direct plunge entry without a pre-drilled hole. Right-hand cut and right-hand flute geometry are standard for conventional CNC milling spindles. The 6.00 mm shank diameter fits standard ER and collet toolholding systems. Overall length is 45.00 mm, making it appropriate for shallow-to-moderate reach applications without the rigidity loss associated with extended-reach configurations.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• WXL finish coating for extended tool life in demanding materials
• 35-degree helix angle promotes chip evacuation and reduces cutting forces
• Centercutting geometry allows direct plunge milling without pilot hole
• 2-flute design keeps gullets open for efficient chip clearance at 0.1339-inch diameter
• Right-hand cut and right-hand flute — compatible with standard CNC spindle rotation

Compatibility

Designed for use in standard ER collet chucks and precision toolholders accepting a 6.00 mm shank diameter. Suitable for CNC machining centers and manual mills configured for right-hand rotation.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and locked out before seating or removing the end mill from its toolholder. Verify collet size matches the 6.00 mm shank before tightening. Inspect the cutting edges for chips or coating damage before each use, as solid carbide tooling is brittle and sensitive to improper handling or side-loading during setup.
