Osg 86301509 Square End Mill 5/8 in 3 Flute Solid Carbide Dlc

Product Description

The OSG 86301509 is a solid carbide square end mill designed for high-performance milling operations in metalworking and machining applications. It features a 5/8 inch mill diameter, a 3-1/8 inch length of cut, and three flutes with a 40-degree helix angle. The DLC (Diamond-Like Carbon) coating reduces friction and improves wear resistance, extending tool life in demanding cutting conditions. The micrograin carbide substrate provides hardness and edge retention suitable for finishing and semi-finishing cuts in ferrous and non-ferrous materials. This tool is single-end and center-cutting, allowing plunge entry as well as peripheral milling.

This end mill is suited for CNC machining centers, vertical mills, and manual milling machines where a 5/8 inch shank is compatible. With a 6 inch overall length and 3-1/8 inch length of cut, it handles deeper pocketing and profiling operations where additional reach is needed. The right-hand cutting and right-hand flute direction are standard for conventional spindle setups. Machinists, tool-and-die makers, and CNC operators in job shops, production facilities, and maintenance departments are the primary users of this tool.

Key Features

• DLC coating reduces friction and extends tool life in demanding milling operations
• Micrograin solid carbide substrate for improved hardness and edge retention
• 40-degree helix angle promotes efficient chip evacuation
• Center-cutting design allows direct plunge entry into workpiece material
• 3-1/8 inch length of cut supports deep pocket and profile milling
• Right-hand cut and right-hand flute direction for standard CNC and manual mill spindles

Compatibility

Designed as an OEM-style solid carbide square end mill for use in standard 5/8 inch collets, end mill holders, and shrink-fit toolholding systems on CNC machining centers and manual vertical mills.

Installation Notes

Installation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet system is locked out before changing tooling. Secure the shank to the full recommended grip depth in the holder to prevent pullout under cutting loads. Always verify runout with a dial indicator after seating the tool before beginning a cut.
