Built from 3% vanadium high speed steel, this tool delivers good wear resistance and edge retention across a range of ferrous and non-ferrous materials. It cuts at 0.9063 inches (29\/32 inches) diameter with a 1.875-inch length of cut and an overall length of 4.125 inches. The right-hand cut, right-hand spiral flute geometry at a 30-degree helix angle promotes efficient chip evacuation. Centercutting capability allows both plunge and ramp entry. This end mill is intended for use by machinists and toolroom professionals on manual and CNC milling machines.\u003c\/p\u003e\u003cp\u003eThe OSG 5743400 fits standard milling applications in job shops, maintenance machining, and production environments. The 0.75-inch shank diameter suits common R8, collet chuck, and end mill holder setups found on Bridgeport-style knee mills and CNC machining centers. The regular-length geometry makes it well-suited for side milling, slotting, and profiling in steel, cast iron, aluminum, and similar materials. It carries no specialized coating, making it a straightforward uncoated HSS option for lower-speed cuts or where re-sharpening is a priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e29\/32 inch (0.9063 inch) cutting diameter with 1.875-inch length of cut\u003c\/li\u003e\n\u003cli\u003e3% vanadium high speed steel construction for improved wear resistance over standard M2 HSS\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes at 30-degree helix angle for balanced chip flow and surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design enables plunge milling and ramp entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle operation\u003c\/li\u003e\n\u003cli\u003eUncoated finish — suitable for re-sharpening and use with cutting fluids\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement end mill for use in standard 0.75-inch collet chucks, R8 collet holders, and end mill holders on manual knee mills and CNC vertical machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist. Ensure the milling machine spindle is fully stopped and locked before inserting or removing the tool from the holder. Verify runout with a dial indicator after seating the shank to confirm proper tool holding.
