Accupro EM99943847 Chamfer Mill 5/8 in 6 Flute Carbide

Product Description

The ACCUPRO EM99943847 is a single-end chamfer mill designed for producing chamfered edges, beveled profiles, and deburring operations on ferrous and non-ferrous workpiece materials. It features a 0.625-inch cutter head diameter and is ground from solid carbide for rigidity and wear resistance. The AlTiN coating extends tool life in high-temperature cutting environments by reducing heat transfer into the substrate. With 6 flutes and a right-hand cutting direction, this mill provides smooth chip evacuation and surface finish on CNC machining centers and manual mills. It is suited for production shops, tool rooms, and precision fabrication environments where consistent chamfer geometry is required.

This chamfer mill is used in metalworking applications where edge preparation, countersinking, or angled profile milling is required. The 3.5-inch overall length and 0.625-inch shank diameter make it compatible with standard end mill holders, collet chucks, and ER-style tooling systems. It is appropriate for ferrous alloys, stainless steel, and hardened steels where AlTiN coating performance is advantageous. Machinists, CNC programmers, and toolroom technicians are the primary users. Coolant-through is not available on this tool, so flood or mist coolant at the periphery is the recommended cooling method.

Key Features

• Solid carbide construction for high rigidity and dimensional stability under load
• AlTiN coating for elevated heat resistance and extended tool life in ferrous and hardened materials
• 6-flute geometry for improved surface finish and reduced vibration during cut
• Single-end design with right-hand cutting direction for standard spindle operation
• 0.273-inch length of cut suited for precise, controlled chamfer depth
• 0.625-inch shank diameter fits standard collet and end mill holder systems

Compatibility

Designed as an OEM-style chamfer mill for use in standard end mill holders, ER collet chucks, and shrink-fit tooling systems accepting a 0.625-inch shank diameter.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is in a safe position before inserting or removing the tool. Verify shank seating depth and holder runout with a dial indicator before initiating a cutting pass. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material and coating type.
