Accupro 95168832 Corner Radius End Mill 0.5in 5 Flute Altin

Product Description

The ACCUPRO 95168832 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and hard alloy materials. It features a 0.500 inch diameter with a 0.0300 inch corner radius and five flutes arranged in a variable helix spiral geometry, which reduces chatter and improves surface finish at higher feed rates. The AlTiN coating provides thermal resistance and wear protection, making this tool well suited for dry or semi-dry cutting applications in hardened steels, cast iron, and similar materials. At 6.000 inches overall length with an extended reach design, it is intended for machinists and tool-and-die professionals requiring access to deep features or pockets without sacrificing rigidity.

This end mill is used in CNC machining centers for profiling, slotting, and contouring operations where a defined corner radius is required to reduce stress concentrations in the finished part. The extended reach of 3.375 inches and a reduced neck diameter of 0.450 inches allow cutting in deeper cavities while maintaining clearance. The single-end, centercutting configuration supports both peripheral and plunge entry. The long length-of-cut classification and 0.625 inch cutting length make it applicable to mold and die work, aerospace component finishing, and production machining of complex profiles.

Key Features

• 0.0300 inch corner radius reduces edge stress and improves part geometry at pocket floors and walls
• Five-flute variable helix design dampens vibration and supports higher material removal rates
• AlTiN coating delivers elevated heat resistance for cutting hardened and abrasive materials
• Extended reach at 3.375 inches with 0.450 inch neck diameter for deep-cavity access
• Centercutting geometry allows direct plunge entry without a pre-drilled start hole
• Right-hand cut and right-hand flute spiral — compatible with standard CNC spindle rotation

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in CNC machining centers and milling machines accepting a 0.500 inch straight shank. No specific compatible machine models were provided in the product data.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's guidelines for tool holding and runout tolerance. Ensure the spindle is fully stopped and the machine is in an e-stop or lock-out state before changing tooling. Use a precision collet or hydraulic chuck to minimize runout, as carbide end mills are sensitive to radial deflection. Inspect the cutting edges and coating before each setup — do not use a chipped or damaged tool.
