Osg 404-4688 Square End Mill 15/32 in 4 Flute Solid Carbide

Product Description

The OSG 404-4688 is a solid carbide square end mill designed for precision milling operations in ferrous and non-ferrous materials. Built from micrograin carbide, it delivers consistent edge integrity and extended tool life under demanding cutting conditions. The 15/32 inch (0.4688 inch) cutting diameter, 30-degree helix angle, and spiral flute geometry work together to produce clean cuts, efficient chip evacuation, and reduced cutting forces. With 4 flutes and a center-cutting configuration, this end mill handles both plunge and peripheral milling. It is suited for use in manual mills and CNC machining centers. Installation and operation are performed by machinists and toolroom professionals.

This end mill fits applications requiring a 1/2 inch shank in standard ER collets, side-lock holders, or shrink-fit tooling. The 1 inch length of cut and 3 inch overall length make it appropriate for shallow-to-medium depth pocketing, slotting, and contouring in production and job-shop environments. It is uncoated and optimized for use with cutting fluid or dry machining depending on the workpiece material. The Series 404 designation places it within OSG's regular-length square end mill line.

Key Features

• Solid micrograin carbide construction for wear resistance and edge stability
• 4-flute, center-cutting design supports both plunge entry and peripheral cutting
• 30-degree helix angle promotes smooth chip flow and reduced vibration
• Right-hand cut, right-hand flute configuration for standard spindle operation
• Uncoated finish suitable for a wide range of workpiece materials
• Regular length profile balances rigidity and reach for general-purpose milling

Compatibility

Designed as an OEM-style tooling solution for use with 1/2 inch collet chucks, end mill holders, and shrink-fit toolholders in manual and CNC milling machines.

Installation Notes

This end mill is installed and operated by qualified machinists. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Seat the shank fully in the holder to the minimum engagement depth recommended by the toolholder manufacturer. Verify runout with a dial indicator before cutting to protect edge life and workpiece accuracy.
