Iscar 5621457 Corner Chamfer End Mill 0.2362 in 3 Flute

Product Description

The ISCAR 5621457 is a solid carbide corner chamfer end mill designed for precision chamfering and edge-breaking operations on ferrous and non-ferrous materials. It features a 0.2362-inch cutting diameter, a 0.5118-inch length of cut, and a 0.0118-inch chamfer width. The three-flute geometry promotes efficient chip evacuation while maintaining surface finish quality. A TiAlN coating provides thermal resistance and extended tool life in demanding cutting environments. With a right-hand cutting and right-hand flute spiral direction, this tool is suited for conventional CNC milling centers. It is centercutting capable, allowing plunge entry when required.

This end mill is intended for use in precision machining applications where consistent chamfer geometry is critical. It fits standard CNC machining centers and manual mills equipped with an appropriate collet or toolholder accepting a 6 mm shank. The regular-length configuration and fine pitch make it well suited for detailed chamfering work on tight-tolerance components in metalworking, toolroom, and production environments. Machinists working in aerospace, die and mold, and general job-shop applications will find this tool appropriate for controlled chamfer blending and edge preparation tasks.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• TiAlN coating for elevated thermal resistance and extended tool life
• Three-flute spiral design with fine pitch for smooth chip flow and surface finish
• Centercutting geometry allows direct plunge entry
• 0.0118-inch chamfer width for precise, repeatable edge preparation
• Right-hand cut and right-hand flute direction for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style solid carbide corner chamfer end mill for use in standard CNC or manual milling machines accepting a 6 mm shank toolholder or collet system.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholding specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Verify collet or chuck bore matches the 6 mm shank diameter and that tool runout is within acceptable tolerance before beginning a cut. Confirm feeds, speeds, and depth of cut are appropriate for the workpiece material and machine capability before operation.
