Osg 3182046 Square End Mill 0.1811 in 2 Flute Carbide

Product Description

The OSG 3182046 is a solid carbide square end mill designed for high-performance milling in metal cutting and precision machining applications. With a 0.1811 inch (4.60 mm) cutting diameter and a 0.3622 inch (9.20 mm) length of cut, this two-flute tool delivers accurate material removal in tight geometries. The WXL finish provides enhanced wear resistance and lubricity, extending tool life in ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. Centercutting geometry allows direct plunge entry without a pre-drilled pilot hole. This end mill is a single-end tool with right-hand cut and right-hand flute orientation.

This end mill is suited for precision milling operations in tool rooms, job shops, and production environments handling tight-tolerance features such as slots, pockets, and profiles. The 0.1811 inch diameter targets small-feature work common in mold making, die work, and aerospace component machining. The solid carbide construction supports use in CNC machining centers where rigidity and repeatability are required. The 6.00 mm (approximately 0.236 inch) shank diameter is compatible with standard collet and end mill holder systems.

Installation Notes

Installation is performed by a machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the end mill. Verify runout after installation using a dial indicator before commencing the cut. Follow machine tool manufacturer torque specifications for collet nut tightening — do not use improvised methods to secure the holder.
