Osg 3182042 Square End Mill 0.1654 in 2 Flute Solid Carbide

Product Description

The OSG 3182042 is a solid carbide square end mill designed for precision milling operations in metal fabrication, moldmaking, and general machining applications. It features a 0.1654-inch (4.2 mm) mill diameter, a 0.3307-inch length of cut, and a 0.2362-inch shank diameter. The two-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting performance. The WXL coating enhances wear resistance and tool life in demanding materials. Micrograin carbide construction provides the rigidity needed for tight-tolerance work. This end mill is a single-end, right-hand cut tool suited for machinists running CNC mills or manual knee mills.

This end mill is suited for applications requiring small-diameter precision cutting, including slot milling, contouring, and profiling in ferrous and non-ferrous materials. The Series 3721 designation places it within OSG's line of high-performance carbide end mills. It is appropriate for job shops, tool-and-die operations, and production environments where consistent dimensional accuracy and extended tool life are priorities.

Installation Notes

Installation is performed by machinists familiar with toolholder torque procedures and runout requirements. Power down and lock out the spindle before changing tooling. Seat the shank fully in the collet or end mill holder and verify runout before beginning a cut. Follow machine manufacturer guidelines for speeds, feeds, and depth of cut appropriate to the workpiece material and tool diameter.
