Osg 484-3937 Square End Mill 0.3937 in 4 Flute Carbide

Product Description

The OSG 484-3937 is a solid carbide square end mill designed for precise milling operations in metal, alloy, and composite workpiece materials. With a 0.3937-inch (10 mm) mill diameter and a 1.7717-inch (45 mm) length of cut, this tool handles slotting, profiling, and peripheral milling where dimensional accuracy matters. The four-flute configuration and 30-degree spiral helix promote efficient chip evacuation and surface finish quality. Manufactured from micrograin carbide, the 484-3937 offers rigidity and wear resistance suited to demanding cutting conditions. It is centercutting, allowing plunge entry into the workpiece. This tool is used by machinists and toolroom professionals in production and job shop environments.

The OSG 484-3937 is suited for use in vertical machining centers, CNC mills, and manual knee mills where a 10 mm shank diameter is compatible with the spindle toolholder. The 100 mm overall length fits standard toolholding setups without requiring extended-reach adapters. Right-hand cut and right-hand flute geometry follow conventional milling conventions. The uncoated finish makes this end mill a straightforward option for general-purpose applications or situations where a specific coating is not required. It fits into Series 484, OSG's line of standard solid carbide square end mills.

Key Features

• 0.3937-inch (10 mm) mill diameter with matching 10 mm shank diameter for direct collet or end mill holder fitment
• 1.7717-inch (45 mm) length of cut handles moderate-depth slotting and profiling passes
• Four-flute spiral design with 30-degree helix angle balances chip flow and cutting stability
• Centercutting geometry allows direct plunge milling without pre-drilling
• Micrograin solid carbide construction provides rigidity and edge retention
• Right-hand cut, right-hand flute — standard orientation for conventional and climb milling

Compatibility

Designed as a standard replacement or stock end mill for setups requiring a 10 mm diameter, 4-flute solid carbide square end mill with a 10 mm shank, within the OSG Series 484 product line.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the tool is secured with appropriate torque in a collet chuck or end mill holder rated for the 10 mm shank diameter before operation. Verify runout with a dial indicator before cutting to avoid premature tool wear or dimensional error. Follow the machine manufacturer's recommended speeds and feeds for solid carbide tooling in the target workpiece material.
