Osg 3182055 Square End Mill 0.2165 in 2 Flute Solid Carbide

Product Description

The OSG 3182055 is a solid carbide square end mill designed for precise milling operations in metal and engineered materials. With a 0.2165-inch (5.5 mm) cutting diameter and a 0.4331-inch (11 mm) length of cut, this tool delivers clean, flat-bottomed profiles in slots, pockets, and peripheral cuts. The 0.2362-inch (6 mm) shank seats securely in standard collet or end mill holders. Center-cutting geometry allows direct plunge entry. This end mill is installed and operated by machinists and toolroom professionals on CNC machining centers and manual milling machines.

This end mill is suited to precision slot milling, step milling, and profiling in applications where tight tolerances and clean surface finish are required. The 2-flute configuration provides efficient chip evacuation in softer metals and provides the chip clearance needed for deeper passes. The 30-degree helix angle balances cutting forces and improves surface quality across a range of work materials. The WXL coating enhances wear resistance and tool life in ferrous and non-ferrous applications. Overall length is 50 mm, making this a compact, rigid tool appropriate for close-tolerance work.

Key Features

• Solid carbide micrograin construction for rigidity and extended tool life
• WXL coating improves wear resistance and reduces heat buildup at the cutting edge
• 30-degree helix angle balances chip flow and cutting forces
• Center-cutting design allows direct plunge entry without pre-drilling
• Right-hand cut, right-hand flute — standard orientation for conventional CNC setups
• 2-flute geometry supports efficient chip evacuation in softer materials

Compatibility

OSG Series 3721 square end mill compatible with standard collet chucks and end mill holders accepting a 0.2362-inch (6 mm) shank diameter. Length of cut range is 0.3000 to 0.5000 inches, suitable for applications within that depth envelope.

Installation Notes

Installation should be performed by qualified machinists following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the holder and torque the set screw or collet nut to the holder manufacturer's specification. Verify runout with a dial indicator after mounting before beginning any cutting operation.
