Iscar 5621679 Chamfer Mill 2mm 4 Flute Solid Carbide

Product Description

The ISCAR 5621679 is a solid carbide chamfer mill designed for chamfering and countersinking operations on metal workpieces. It features a 2 mm cutter head diameter, a 4-flute configuration, and a TiAlN coating that improves heat resistance and tool life during high-speed cutting. With a 6 mm shank diameter and an overall length of 57 mm, this tool is sized for compact, precision work in CNC machining centers and manual mills. The right-hand cutting direction suits standard spindle configurations. Machinists and tool-and-die professionals use this tool for deburring edges, preparing hole entries, and generating angled chamfer profiles.

This chamfer mill is suited for applications in carbon steel, hard alloys, and stainless steel. Its solid carbide construction handles the demands of harder workpiece materials where high-speed steel tooling would wear prematurely. Typical use cases include chamfering drilled or bored holes before tapping, preparing mating part edges for assembly, and countersinking fastener seats. The TiAlN coating supports dry or semi-dry cutting conditions, reducing the need for flood coolant in many setups.

Key Features

• 2 mm cutter head diameter for small-diameter chamfer and countersink work
• 4-flute geometry for improved finish and chip evacuation
• Solid carbide construction for rigidity and wear resistance in hard materials
• TiAlN coating enhances heat resistance and extends tool life
• 6 mm shank diameter for standard ER and collet chuck compatibility
• Right-hand cutting direction for use in standard CNC and manual spindles

Compatibility

Designed for use on carbon steel, hard alloys, and stainless steel workpieces. Compatible with standard 6 mm collet chucks and ER-style tool holders used in CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist following standard toolholding procedures. Ensure the spindle is fully stopped and the machine is powered down before loading or unloading the tool. Seat the shank fully and evenly in the collet or chuck and torque the retention nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut, as runout on a small-diameter tool accelerates wear and affects chamfer quality.
