Osg 404-2812 Square End Mill 9/32 Inch 4 Flute Carbide

Product Description

The OSG 404-2812 is a solid carbide square end mill designed for precise milling operations in metalworking and machining applications. It features a 9/32 inch (0.2813 inch) cutting diameter, a 3/4 inch length of cut, and a 5/16 inch shank diameter with a 2-1/2 inch overall length. Built from micrograin solid carbide, this uncoated, four-flute tool delivers consistent performance in general-purpose milling. The 30-degree right-hand spiral flute geometry promotes efficient chip evacuation, and the centercutting design allows for direct plunge entry into the workpiece. It is suited for CNC machining centers and manual mills used in production and job-shop environments.

This end mill is sized for close-tolerance slotting, profiling, and pocketing work where a smaller diameter cutter is required. The regular length configuration and 5/16 inch shank make it compatible with standard collet and end mill holder setups. Machinists working with ferrous and non-ferrous materials will find the uncoated micrograin carbide construction appropriate for dry cutting or flood coolant applications. It is a single-end tool sold individually and suited for light to moderate material removal at smaller feature sizes.

Key Features

• Micrograin solid carbide construction for wear resistance and edge retention
• 4-flute design balances chip clearance with surface finish quality
• 30-degree right-hand helix promotes smooth chip evacuation
• Centercutting geometry allows plunge milling capability
• Uncoated finish suitable for use with or without coolant
• Regular length profile fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for CNC machining centers and manual milling machines accepting a 5/16 inch shank diameter with standard collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the collet or end mill holder and torque the retention hardware according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut to protect the tool and workpiece.
