Accupro EM99943853 Chamfer Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO EM99943853 is a solid carbide chamfer mill designed for precision chamfering and deburring operations on metal workpieces. Built with a 1/2 inch cutter head diameter and 4 flutes in a right-hand cutting configuration, this tool delivers clean, consistent chamfer geometry at the spindle. The AlTiN coating provides elevated heat resistance and extended tool life in high-speed dry or semi-dry cutting environments. With a 6 inch overall length and a 1/2 inch shank diameter, it fits standard end mill holders used across vertical and horizontal machining centers. This is a single-end tool intended for professional CNC or manual milling setups.

This chamfer mill is suited for use in job shops, production machining environments, and toolroom applications where precise edge preparation is required. It performs well on ferrous metals and hardened steels where the AlTiN coating's thermal stability offers a measurable advantage. Typical applications include pre-weld chamfering, countersinking thread lead-ins, and part deburring on prismatic components. It is installed and operated by machinists and CNC technicians working with standard milling equipment.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for high-temperature performance and extended tool life
• 4-flute design for efficient chip evacuation and surface finish
• Right-hand cutting direction for standard spindle compatibility
• Single-end geometry with 0.158 inch length of cut
• 6 inch overall length with 1/2 inch shank for broad holder compatibility

Compatibility

Designed as a direct-fit replacement chamfer mill for standard 1/2 inch end mill holders and collet chucks used in CNC machining centers and manual milling machines.

Installation Notes

Installation is performed by a qualified machinist or CNC technician. Ensure the spindle is fully stopped and the machine is in a safe lockout state before changing tooling. Seat the 1/2 inch shank fully in the holder and tighten to the holder manufacturer's specified clamping torque using the appropriate wrench. Verify runout with a dial indicator before beginning production cuts.
