Osg 3182054 Square End Mill 0.2126in 2 Flute Solid Carbide

Product Description

The OSG 3182054 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.2126-inch cutting diameter, a 0.4252-inch length of cut, and a 0.2362-inch shank diameter, this end mill suits tight-tolerance work where dimensional accuracy is critical. The 2-flute, right-hand cut geometry pairs with a 30-degree helix angle to promote chip evacuation and reduce heat buildup during cutting. The WXL coating enhances wear resistance and extends tool life in demanding materials. Manufactured from micrograin solid carbide, this tool delivers the rigidity and edge retention required for consistent performance in production environments.

This end mill is suited for use in CNC machining centers and manual mills where small-diameter, high-precision cuts are required. The centercutting design allows for plunge milling as well as peripheral cutting. With an overall length of approximately 50 millimeters and a 6.00-millimeter shank, it fits standard collet and toolholder systems used in light to medium milling applications across aerospace, tool-and-die, and general metalworking shops.

Key Features

• 0.2126-inch cutting diameter with 0.4252-inch length of cut for controlled material removal
• 2-flute, right-hand cut and right-hand flute configuration for standard climb and conventional milling
• 30-degree helix angle promotes efficient chip flow and reduces chatter
• Centercutting geometry allows plunge entry without a pre-drilled hole
• WXL coating improves wear resistance and tool life in ferrous and non-ferrous materials
• Micrograin solid carbide construction provides superior rigidity and edge retention

Compatibility

Designed as a replacement-grade solid carbide square end mill in the OSG Series 3721 line, compatible with standard collet systems and toolholders accepting a 0.2362-inch (6.00 mm) shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety protocols. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or toolholder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a production cut.
