Accupro EM99943837 Chamfer Mill 0.25 in 3 Flute Altin Carbide

Product Description

The ACCUPRO EM99943837 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous workpieces. It features a 0.25 inch cutter head diameter, three flutes for efficient chip evacuation, and an AlTiN coating that extends tool life in high-heat cutting environments. The right-hand cutting geometry produces clean, consistent chamfer angles in a single pass. This tool is installed and used by machinists, toolroom operators, and CNC programmers working with machining centers and manual mills.

This chamfer mill is suited for production and job-shop environments where repeatable edge preparation is required. The single-end design with a 0.25 inch shank diameter makes it compatible with standard collet chucks and end mill holders found on vertical machining centers, knee mills, and multi-axis CNC platforms. The AlTiN coating performs well in dry cutting and semi-dry conditions, reducing the need for flood coolant on compatible materials.

Key Features

• Solid carbide construction for rigidity and wear resistance
• AlTiN coating for elevated-temperature performance and extended tool life
• Three flutes for balanced chip load and smooth finish
• Right-hand cutting direction for standard spindle rotation
• 0.165 inch length of cut for controlled edge engagement
• No coolant-through design, suited for external coolant or dry cutting

Compatibility

Designed as an OEM-style replacement chamfer mill for use in standard 0.25 inch collet chucks and end mill holders on CNC and manual milling platforms.

Installation Notes

Installation is performed by machinists or CNC setup technicians. The machine spindle must be fully stopped and the tool changer or spindle lock engaged before changing tooling. Secure the shank fully within the collet or holder to the recommended engagement depth per the toolholder manufacturer before torquing. Verify runout with a dial indicator after installation to prevent premature edge wear or tool failure.
