Osg 8549922 Square End Mill 12mm 4-flute Solid Carbide

Product Description

The OSG 8549922 is a solid carbide square end mill designed for precision milling operations in metalworking and machining environments. It features a 12 mm (0.4724 inch) cutting diameter, a 30 mm length of cut, and four flutes with a variable helix geometry that helps reduce chatter and improve chip evacuation. The Duarise coating provides enhanced surface hardness and wear resistance for extended tool life in demanding cutting conditions. This end mill is intended for use by machinists and tool-and-die professionals working on CNC machining centers and manual mills.

This end mill suits a range of milling applications including slotting, profiling, and peripheral milling on ferrous and non-ferrous materials. With a 10 mm shank diameter and 150 mm overall length, it fits standard collet and end mill holders common in production and job-shop environments. The single-end, right-hand cutting configuration and right-hand flute direction make it a straightforward drop-in for conventional right-hand spindle setups. The centercutting capability allows plunge entry where required.

Key Features

• 12 mm cutting diameter with 0.4724 inch decimal equivalent for cross-reference
• 30 mm length of cut suits moderate-depth slotting and profiling passes
• Variable helix design reduces harmonic vibration and improves surface finish
• Duarise coating delivers enhanced wear resistance and thermal stability
• Micrograin solid carbide substrate provides rigidity and edge retention
• Centercutting geometry allows direct plunge entry without a pre-drilled hole

Compatibility

Designed for use in standard 10 mm collet chucks and end mill holders on CNC machining centers and manual vertical mills with right-hand spindle rotation.

Installation Notes

This tool should be installed by a qualified machinist following the machine tool manufacturer's toolholding torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Verify collet condition and holder concentricity before use, as excessive runout will accelerate edge wear. Follow applicable shop safety standards and machine guarding requirements during operation.
