Accupro EM99943849 Chamfer Mill 1/4 in 3 Flute Carbide

Product Description

The ACCUPRO EM99943849 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous workpieces. It features a 1/4 inch cutter head diameter, three flutes for efficient chip evacuation, and a right-hand cutting direction. The AlTiN coating provides elevated heat resistance and extended tool life in demanding cutting environments. With a 4 inch overall length and a 1/4 inch shank diameter, this tool is sized for standard 1/4 inch collet or end mill holders commonly found on CNC machining centers and manual mills. Machinists and tool-room operators working in production and job-shop settings will find this a reliable single-end chamfer solution.

This chamfer mill suits applications where controlled chamfer geometry and clean edge preparation are required. The single-end configuration makes it straightforward to index and set. It is appropriate for use on steel, stainless, cast iron, aluminum, and similar materials where AlTiN coatings perform well at moderate to high surface speeds. The 0.1580 inch length of cut keeps the cutting zone compact, which reduces deflection and improves surface finish on shallow chamfer passes.

Key Features

• Solid carbide construction for rigidity and wear resistance compared to HSS alternatives
• AlTiN coating for high-temperature performance and extended tool life
• Three flutes for balanced chip load and smooth cutting action
• Right-hand cutting direction compatible with standard spindle rotation
• Single-end design for straightforward tool setting and replacement
• 0.1580 inch length of cut minimizes deflection on shallow chamfer passes

Compatibility

Designed as an OEM-style chamfer mill for use in standard 1/4 inch end mill holders, collet chucks, or side-lock holders on CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist. Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the holder and torque the retention mechanism to the holder manufacturer specification. Verify runout with a dial indicator before commencing production cuts, as excessive runout accelerates edge wear on carbide tooling.
