Accupro 12177314 Corner Radius End Mill 0.5mm 2 Flute Carbide

Product Description

The ACCUPRO 12177314 is a solid carbide corner radius end mill designed for high-precision milling operations in demanding machining environments. It features a 0.5 mm mill diameter with a 0.05 mm corner radius and a 0.5 mm length of cut, making it suited for fine detail work and tight-tolerance finishing passes. The tool carries an AlTiN (aluminum titanium nitride) coating, which improves hardness and heat resistance at the cutting edge. With a 2-flute, right-hand spiral configuration and a 30-degree helix angle, it is built for accurate material removal in small-diameter applications. Machining centers, CNC mills, and Swiss-type machines are typical platforms for this tool.

This end mill is intended for use in precision CNC milling applications where corner geometry control is critical. It is a single-end, centercutting tool, meaning it can be used for plunge and slot operations as well as peripheral cuts. The extended reach design, with a 5 mm reach length and a 4 mm shank diameter, allows it to access recessed features or stepped pockets without interference. It is commonly installed by CNC machinists and tool-and-die professionals working in aerospace, medical device, mold-and-die, and precision parts manufacturing.

Key Features

• 0.5 mm mill diameter with 0.05 mm corner radius for precise edge geometry
• AlTiN coating provides elevated heat and wear resistance during high-speed cuts
• Solid micrograin carbide construction for rigidity and edge retention in small diameters
• 2-flute, right-hand spiral with 30-degree helix angle for efficient chip evacuation
• Centercutting design allows plunge milling and slotting operations
• Extended reach with 5 mm reach length suits recessed or deep-pocket features

Compatibility

Designed as an OEM-style precision cutting tool compatible with CNC milling machines and machining centers accepting a 4 mm straight shank.

Installation Notes

Tool installation should be performed by a qualified CNC machinist with the spindle fully stopped and machine in a safe, locked-out state. Use a precision collet or end mill holder rated for the 4 mm shank diameter to ensure runout is minimized. Verify tool projection and reach length against the workpiece setup before starting the program. Follow the tool manufacturer cutting data recommendations for feed rate and spindle speed when working at this diameter.
