Osg 86300809 Square End Mill 3/8 Inch 3 Flute Solid Carbide

Product Description

The OSG 86300809 is a solid carbide square end mill designed for precision milling in demanding metal-cutting applications. With a 3/8-inch cutting diameter and a 1-1/8-inch length of cut, this tool removes material efficiently in slots, pockets, and peripheral milling operations. The DLC (Diamond-Like Carbon) finish reduces friction and extends tool life in abrasive materials. A 40-degree helix angle promotes smooth chip evacuation and helps maintain surface finish quality. Three flutes provide a balance between chip clearance and rigidity. Centercutting geometry allows plunge entry directly into the workpiece. This end mill is suited for use in CNC machining centers and manual mills operated by machinists and tool-and-die professionals.

The OSG 86300809 is a single-end configuration intended for use in ferrous and non-ferrous milling applications where tight tolerances and surface quality are required. The solid carbide construction provides the stiffness needed for high-speed cutting in steel, stainless steel, aluminum, and similar materials. The right-hand cut and right-hand flute direction are standard for conventional CNC setups. With a 3/8-inch shank diameter and a 3-inch overall length, this end mill fits standard collet chucks and end mill holders commonly found in production and job-shop environments.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• DLC finish reduces friction and extends tool life in demanding cuts
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry without a pre-drilled pilot hole
• 3 flutes balance chip clearance with core strength for stable milling
• Right-hand cut and right-hand flute direction compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style replacement and production end mill for CNC machining centers and manual mills accepting a 3/8-inch shank via standard collet chucks or end mill holders.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling change procedures. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill from the holder. Verify collet or holder bore matches the 3/8-inch shank diameter before clamping. Consult the machine manufacturer and OSG cutting data guidelines for recommended speeds, feeds, and depth-of-cut parameters for the specific workpiece material.
