Osg 403-0787 Square End Mill 0.0787 in 3 Flute Carbide

Product Description

The OSG 403-0787 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0787 inch (2.00 mm) cutting diameter and a 0.2756 inch (7.00 mm) length of cut, this tool is built for small-feature work where tight tolerances and clean square floors are required. The 3-flute geometry balances chip evacuation with rigidity, making it well suited to a range of ferrous and non-ferrous materials. A 30-degree helix angle promotes smooth cutting action and reduces cutting forces. Licensed machinists and CNC operators are the primary users of this tool in production and job-shop environments.

This end mill fits applications requiring a compact cutting diameter with a regular-length reach. It is center-cutting, allowing plunge entry directly into the workpiece, which expands its use in slotting, profiling, and pocket-milling operations. The right-hand cut and right-hand spiral flute configuration is the standard setup for conventional CNC machining centers and manual mills. The uncoated carbide substrate is appropriate for dry or lubricated cutting depending on the workpiece material and shop practice.

Key Features

• 0.0787 inch (2.00 mm) cutting diameter for small-feature and fine-detail milling
• 3-flute design balances chip clearance and tool strength
• 30-degree helix angle for smooth, reduced-force cutting
• Center-cutting geometry permits direct plunge entry
• Right-hand cut with right-hand spiral flute — standard CNC configuration
• Solid carbide construction for rigidity and wear resistance

Compatibility

Designed as a standard square end mill replacement for CNC machining centers and manual mills accepting a 3.00 mm (0.118 inch) shank diameter, part of the OSG Series 403 regular-length end mill line.

Installation Notes

Installation is performed by machinists using an appropriate collet or end mill holder rated for the 3.00 mm shank diameter. Ensure the spindle and machine are fully powered down and locked out before changing tooling. Confirm runout with a dial indicator after seating to protect tool life and part accuracy. Follow the machine tool manufacturer and shop safety standards when determining feeds, speeds, and cutting fluid use.
