Osg 5463108 Square End Mill 3/4 Inch 4 Flute Ticn

Product Description

The OSG 5463108 is a 4-flute square end mill designed for milling operations in ferrous and non-ferrous metals. It features a TiCN (Titanium Carbonitride) coating that improves surface hardness and wear resistance compared to uncoated tooling. The 30-degree helix angle promotes smooth chip evacuation and reduces cutting forces during full-depth slotting and profiling passes. Built from M42 cobalt high-speed steel, this tool handles harder workpiece materials at moderate cutting speeds. It is used by machinists and tool-and-die professionals on manual mills and CNC machining centers.

This end mill suits long-reach applications where standard-length tooling cannot achieve the required depth of cut. With a 3-inch length of cut and an overall length of 5.25 inches, it is classified as a long-series tool appropriate for deep pockets, open slots, and stepped features. The centercutting design allows plunge milling directly into a workpiece without a pre-drilled entry point. Right-hand cut and right-hand helix geometry follow standard milling conventions on conventional and climb-milling setups.

Key Features

• TiCN coating increases surface hardness and extends tool life on harder steels
• M42 cobalt HSS substrate maintains hardness at elevated cutting temperatures
• 30-degree helix angle promotes chip flow and reduces cutting pressure
• Centercutting geometry allows direct plunge entry without pilot hole
• Long-series length of cut supports deep pocket and slot milling
• 4-flute configuration balances material removal rate with chip clearance

Compatibility

Designed as a direct-fit tooling replacement for milling applications requiring a 3/4 inch diameter, 3/4 inch straight shank end mill with a long length of cut in OSG Series 546.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Secure the 3/4 inch straight shank in a matching collet chuck or end mill holder and verify runout before cutting. Confirm spindle speed and feed rate are appropriate for the workpiece material and coating type before engaging the cut. Inspect the cutting edges for chipping or wear at regular intervals, and never exceed the rated depth of cut for the flute length.
