Osg 484-125008 Square End Mill 1/8 in 4 Flute Carbide Ticn

Product Description

The OSG 484-125008 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. With a 1/8 inch cutting diameter, a 1 inch length of cut, and a 3 inch overall length, this tool fits standard 1/8 inch collet and toolholder setups. The four-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation and smooth surface finish. A titanium carbonitride (TiCN) coating adds surface hardness and wear resistance, extending tool life in demanding cutting conditions. The micrograin carbide substrate provides edge retention at higher feed rates. Centercutting geometry allows both plunge and conventional milling entries.

This end mill is suited for machining operations requiring tight tolerances and fine detail work, particularly in milling centers and CNC machining environments. The extra-long length classification with a 1 inch length of cut makes it appropriate for slot milling, profiling, and peripheral cuts in shallow-to-moderate depth applications. It is typically used by machinists and tool-and-die professionals working in job shops, production facilities, and maintenance machine shops.

Key Features

• Solid micrograin carbide construction for edge retention and rigidity
• TiCN coating for increased surface hardness and wear resistance
• 4-flute right-hand spiral design with 30-degree helix angle for efficient chip flow
• Centercutting capability allows direct plunge entry into workpiece
• Right-hand cut and right-hand flute geometry for standard spindle compatibility
• Mill diameter tolerance of +0.000 / -0.001 inches for consistent fit and finish

Compatibility

Designed for use in CNC machining centers and manual mills equipped with 1/8 inch collets or end mill holders; part of the OSG Series 484 product line.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer's clamping specifications. Ensure the spindle is fully powered down and the machine is in a safe state before changing tooling. Verify collet size and runout with a dial indicator before operation. Follow applicable shop safety standards and machine tool manufacturer guidelines for speeds and feeds based on workpiece material.
