Osg 482-2501 Square End Mill 1/4 Inch 2 Flute Carbide

Product Description

The OSG 482-2501 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 1/4 inch cutting diameter and 1 inch length of cut, this two-flute end mill delivers clean, accurate profiles in a range of ferrous and non-ferrous materials. The micrograin carbide construction provides rigidity and wear resistance in demanding cutting conditions. A 30-degree helix angle promotes efficient chip evacuation, and the centercutting geometry allows direct plunge entry into the workpiece. Machinists and tool-and-die professionals install this tool in CNC machining centers and manual mills.

This end mill is suited for slotting, profiling, and plunge operations in job shop, production, and maintenance machining environments. The 1/4 inch shank fits standard collets and end mill holders, making it a practical choice for light-duty CNC work, mold and die detail work, and precision contouring. The uncoated finish allows for direct inspection of tool wear and is compatible with coolant or dry cutting strategies depending on the material and machine setup.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• 2-flute design promotes chip clearance in slotting and profiling cuts
• 30-degree spiral flute helix angle aids chip evacuation
• Centercutting geometry enables direct plunge milling
• Right-hand cut and right-hand flute configuration for standard spindle rotation
• Uncoated finish for versatile use across a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct substitution for 1/4 inch shank square end mills in standard ER collets, end mill holders, and shrink-fit tooling systems accepting a 0.2500 inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC operators. Power down and lock out the machine spindle before inserting or removing tooling. Ensure the collet or tool holder is clean and free of debris before seating the shank to the correct engagement depth. Follow the machine tool manufacturer torque specifications for collet nut tightening and verify runout with a dial indicator before initiating a cut.
