Osg 5743908 Square End Mill 1 in 4 Flute Vanadium Hss Ticn

Product Description

The OSG 5743908 is a single-end square end mill designed for general-purpose milling operations in ferrous and non-ferrous materials. Built from 3% vanadium high speed steel, it delivers improved wear resistance and edge retention compared to standard M2 HSS tooling. The TiCN coating further extends tool life by reducing friction and heat buildup at the cutting edge. At 1 inch in diameter with a 2-inch length of cut and a 4-flute configuration, this end mill suits slotting, profiling, and peripheral milling in a wide range of shop and production environments. Machinists and toolroom operators are the primary users of this tool.

This end mill is suited for use on vertical machining centers, knee mills, and manual or CNC milling machines where a 1-inch shank is accommodated. The 30-degree helix angle promotes smooth chip evacuation and stable cutting action during side milling and full-slot operations. The centercutting geometry allows plunge entry, giving operators flexibility when programming tool paths or working manually. At 4-1/2 inches overall length, this is a standard-reach tool appropriate for most conventional setups without requiring extended-reach holders.

Key Features

• 3% vanadium high speed steel construction for enhanced hardness and wear resistance over standard HSS
• TiCN coating reduces friction and extends tool life in ferrous materials
• Centercutting design permits direct plunge entry without pre-drilling
• 30-degree helix angle promotes chip clearance and reduces cutting forces
• 4-flute spiral configuration balances material removal rate with surface finish quality
• Right-hand cut and right-hand flute geometry for standard milling machine spindle direction

Compatibility

Designed for use in milling machines and machining centers accepting a 1-inch straight shank, standard ER or end mill holders, or equivalent toolholding systems.

Installation Notes

Installation and tool changes must be performed with the machine powered off and the spindle fully stopped. Secure the shank in a properly sized end mill holder or collet chuck and torque the set screw or collet nut according to the holder manufacturer's specifications. Inspect the cutting edges and coating for chips or damage before each use. Consult applicable shop safety standards and machine manufacturer guidelines when selecting speeds and feeds for the material being cut.
