Osg 5732400 Square End Mill 11/16 in 2 Flute Vanadium Hss

Product Description

The OSG 5732400 is a square end mill designed for general-purpose milling in ferrous and non-ferrous materials. Built from 3% vanadium high speed steel, it offers improved wear resistance and edge retention compared to standard M2 HSS tooling. The 11/16-inch diameter cutting face paired with a 30-degree right-hand spiral flute geometry promotes efficient chip evacuation and stable cutting action. With two flutes and a centercutting design, this end mill handles slotting, profiling, and plunge operations. Machinists and tool-and-die shops reach for this tool when carbide is unnecessary or cost-prohibitive for the application.

This end mill suits light-to-medium milling operations on manual knee mills, CNC machining centers, and bridgeport-style machines running conventional or climb milling passes. The 1-5/16-inch length of cut accommodates moderate-depth slot and pocket work. The 5/8-inch shank diameter fits standard ER and side-lock holders commonly found in production and job-shop environments. It is sold as a single-end tool and is not regrind-designated by the input data.

Key Features

• 3% vanadium high speed steel construction for enhanced hardness and wear resistance over standard HSS
• 30-degree right-hand spiral flute for positive chip lift and reduced cutting forces
• Centercutting geometry allows direct plunge entry without pre-drilling
• Two-flute design maximizes chip clearance in slot milling and deep-pocket applications
• Uncoated finish suitable for use with cutting fluids on a wide range of workpiece materials
• Regular-length series 573 geometry provides rigidity with adequate reach for most shop applications

Compatibility

Designed as a standard shank square end mill compatible with 5/8-inch end mill holders, ER collet chucks, and side-lock (Weldon) holders used in vertical milling machines and CNC machining centers.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked. Ensure the holder bore and shank are clean and free of chips or coolant residue before seating the tool. Tighten the set screw or collet nut to the holder manufacturer's specified torque range using the appropriate wrench — do not use extensions that could over-torque the retaining hardware. Verify runout with a dial indicator before commencing cuts when tight tolerances are required.
