Osg 482-1181 Square End Mill 0.1181 in 2 Flute Carbide

Product Description

The OSG 482-1181 is a solid carbide square end mill designed for precision material removal in demanding machining environments. With a cutting diameter of 0.1181 inches (3.00 mm) and a length of cut of 0.9843 inches (25.00 mm), this tool delivers consistent performance in tight-tolerance applications. The two-flute, right-hand spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Micrograin carbide construction provides the hardness and edge retention needed for high-speed cutting. This is a center-cutting tool, allowing plunge entry into the workpiece.

The 482-1181 is suited for milling operations in ferrous and non-ferrous materials where a small-diameter, extra-long reach tool is required. Its uncoated micrograin carbide construction makes it a versatile option for slotting, profiling, and contouring in die, mold, and precision component work. The extra-long length of cut classification supports access to deep features and recessed pockets that standard-length end mills cannot reach. Machinists and tool-and-die professionals will find this tool at home in CNC machining centers and manual mills handling small, detailed workpieces.

Key Features

• 0.1181 inch (3.00 mm) cutting diameter for small-diameter precision work
• 0.9843 inch (25.00 mm) length of cut — extra-long classification for deep-feature access
• 2-flute, right-hand cut with right-hand spiral flute for efficient chip clearing
• 30-degree helix angle promotes smooth cutting action and reduced chatter
• Center-cutting design allows direct plunge entry without a pre-drilled pilot hole
• Micrograin solid carbide construction for superior hardness and edge retention

Compatibility

Designed as a direct-fit replacement or standard tooling selection within the OSG Series 482 extra-long square end mill line, compatible with collet and tool holders accepting a 3.00 mm (0.1181 inch) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or tool holder and torque the retention mechanism to the tool holder specification. Verify runout with a dial indicator before beginning a cut, as runout is especially critical at small diameters.
