Osg 8549750 Square End Mill 5mm 4 Flute Solid Carbide

Product Description

The OSG 8549750 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 5 mm cutting diameter and a 12.5 mm length of cut, with four flutes ground from micrograin carbide for consistent edge integrity. The 43-degree helix angle promotes efficient chip evacuation and reduced cutting forces. A DUROREY coating adds surface hardness and thermal resistance, extending tool life in demanding materials. This end mill ships as a single-end tool and is installed by machinists and CNC operators on vertical machining centers, knee mills, and multi-axis platforms.

This end mill is suited for finish and semi-finish milling of ferrous and non-ferrous materials in both job-shop and production environments. The 6 mm shank diameter fits standard ER collet chucks and shrink-fit toolholders. The 60 mm overall length keeps the tool compact for close-tolerance work in shallow-to-medium pockets. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling passes. Centercutting geometry allows plunge entry when needed.

Key Features

• 5 mm cutting diameter with 12.5 mm length of cut for controlled depth passes
• 4-flute configuration in micrograin solid carbide for edge sharpness and rigidity
• 43-degree helix angle for aggressive chip evacuation and smooth surface finish
• DUROREY coating for improved wear resistance and thermal protection
• Centercutting design permits direct plunge entry
• Right-hand cut and right-hand flute direction for standard spindle rotation

Compatibility

Designed as a standard-shank solid carbide square end mill with a 6 mm shank diameter, compatible with ER collet systems and other toolholding systems accepting 6 mm round shanks on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the toolholder manufacturer torque and runout specifications. Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before changing tooling. Seat the shank to the minimum recommended insertion depth for the collet or chuck in use. Verify runout at the cutting diameter before beginning a production cut.
