Osg 3181838 Square End Mill 0.1496in 2 Flute Solid Carbide

Product Description

The OSG 3181838 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. With a mill diameter of 0.1496 inches (3.8 mm) and a 2-flute spiral configuration, this tool is built for efficient material removal in tight-tolerance applications. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces. The WXL coating improves wear resistance and extends tool life in demanding materials. This end mill is a stub-length design, offering added rigidity over longer-reach alternatives. It is installed and operated by machinists and CNC tooling professionals.

The OSG 3181838 is suited for use in CNC machining centers and manual milling applications where a small-diameter, right-hand cut end mill is required. The stub-length format is ideal for setups where overhang must be minimized to maintain rigidity and dimensional accuracy. With a shank diameter of 0.2362 inches (6.00 mm) and a length of cut of 0.2244 inches (5.7 mm), this tool fits standard collet and end mill holder configurations used in precision shop environments.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or end mill holder and torque the retention mechanism to the tool holder manufacturer's specification. Verify runout with a dial indicator before commencing cutting operations.
