Osg 20152711 Corner Radius End Mill 1in 4 Flute Tialn Carbide

Product Description

The OSG 20152711 is a solid carbide corner radius end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a 1-inch cutting diameter, a 1-1/2-inch length of cut (LOC), and a 0.06-inch corner radius that reduces stress concentrations at the base of cuts and extends tool life. The TiAlN coating provides thermal resistance and hardness at elevated cutting temperatures. With four flutes and a right-hand helix, the tool delivers efficient chip evacuation and a fine pitch for smooth surface finishes. This is a centercutting tool, allowing plunge entry and slotting capability.

The OSG 20152711 is suited for milling operations in machining centers and CNC mills across aerospace, die and mold, and general metalworking applications. Its regular-length geometry fits standard toolholding setups. The 1-inch shank diameter provides rigid clamping in collets and end mill holders. The 4-inch overall length (OAL) keeps deflection low during side milling, contour milling, and pocket roughing or finishing passes. This tool is intended for use by machinists and tooling specialists working with tighter tolerances and corner-profile requirements.

Key Features

• 1-inch cutting diameter with 1-1/2-inch LOC for substantial material removal depth
• 0.06-inch corner radius reduces stress risers and extends cutter life at part corners
• TiAlN coating provides high-temperature hardness and wear resistance
• Solid carbide construction for rigidity and dimensional accuracy
• Centercutting design allows direct plunge entry into workpieces
• Right-hand cut, right-hand helix, fine pitch for smooth finishes and stable cutting forces

Compatibility

Designed as an OEM-style replacement or standard fitment for CNC machining center setups requiring a 1-inch shank, 4-flute solid carbide corner radius end mill in the OSG Series 2015 line.

Installation Notes

Installation is performed by qualified machinists and toolroom personnel. Secure the 1-inch shank firmly in a compatible collet, end mill holder, or hydraulic chuck before operation. Ensure the toolholder and spindle are clean and undamaged prior to mounting. Follow machine manufacturer guidelines and applicable shop safety procedures for runout inspection and tool offset entry before engaging the cut.
