Iscar 5621693 Corner Chamfer End Mill 0.375 in 4 Flute

Product Description

The ISCAR 5621693 is a solid carbide corner chamfer end mill designed for precision edge preparation and chamfering operations on ferrous and non-ferrous workpiece materials. The tool measures 0.375 inches in cutting diameter with a 0.75-inch length of cut and a 0.012-inch chamfer width at the corner. A TiAlN coating provides thermal resistance and extended tool life at elevated cutting speeds. The 45-degree helix and four-flute geometry promote smooth chip evacuation and stable cutting action. Machinists and CNC operators install this end mill in milling machines and machining centers for deburring, edge breaking, and chamfer blending on precision components.

This end mill is suited for production and job-shop environments where consistent chamfer geometry is required. The centercutting design allows plunge entry, adding application flexibility on vertical machining centers and similar equipment. The right-hand cutting and right-hand flute direction make it compatible with standard spindle configurations. At 3 inches overall length with a 3/8-inch shank diameter, it fits standard ER and side-lock toolholders commonly used in CNC setups.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cutting conditions
• TiAlN coating for high-temperature performance and extended tool life
• 0.012-inch chamfer width for precise, repeatable corner geometry
• Centercutting design allows plunge milling capability
• Four-flute, right-hand spiral geometry promotes stable cuts and efficient chip removal
• Regular length profile fits standard toolholders without extended-reach adapters

Compatibility

Designed as an OEM-style solid carbide corner chamfer end mill compatible with standard 3/8-inch bore ER collet chucks, side-lock holders, and shrink-fit toolholders used in CNC milling applications.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before seating or removing the tool from the toolholder. Ensure the shank is fully engaged in the collet or holder to the recommended grip depth and that runout is verified before cutting. Refer to the machine tool manufacturer and cutting tool guidelines for appropriate speeds and feeds for the workpiece material.
