Osg 404-0787 Square End Mill 0.0787 in 4 Flute Carbide

Product Description

The OSG 404-0787 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. With a 0.0787 inch (2.00 mm) cutting diameter and a 0.2362 inch (6.00 mm) length of cut, this tool is built for tight-tolerance work in small-feature milling. The four-flute spiral design with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, the 404-0787 delivers rigidity and wear resistance suited to demanding shop environments. It ships uncoated and is centercutting-capable, allowing direct plunge entry into workpiece material.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and pocketing operations where small diameters and precise feature geometry are required. The 3.00 mm shank diameter and 38.00 mm overall length suit compact toolholding setups. It is appropriate for machinists and toolroom operators working with ferrous and non-ferrous metals, plastics, and composites where micrograin carbide performance is specified. Right-hand cut and right-hand flute orientation are standard for conventional toolholder compatibility.

Key Features

• 0.0787 inch (2.00 mm) cutting diameter for small-feature and fine-detail milling
• 4-flute spiral design with 30-degree helix angle for efficient chip removal
• Micrograin solid carbide construction for rigidity and extended tool life
• Centercutting geometry allows direct plunge entry without pre-drilling
• Right-hand cut and right-hand flute for standard spindle and toolholder compatibility
• Uncoated finish suitable for use with cutting fluids or dry machining depending on application

Compatibility

Designed as a direct-fit replacement or standard toolroom selection for OSG Series 404 solid carbide square end mills. Compatible with toolholders accepting a 3.00 mm shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder matched to the 3.00 mm shank diameter to prevent runout and tool pullout. Follow shop safety procedures and machine manufacturer guidelines when setting tool length offsets and cutting parameters.
