Accupro EM99943854 Chamfer Mill 1/4 in 2 Flute Carbide

Product Description

The ACCUPRO EM99943854 is a solid carbide chamfer mill designed for chamfering, deburring, and edge-breaking operations on ferrous and non-ferrous metals. The 1/4 inch cutter head diameter and 2-flute geometry deliver clean, controlled cuts in both manual and CNC machining centers. An AlTiN coating provides elevated hardness and heat resistance, extending tool life in high-temperature cutting environments. Overall length is 2.5 inches with a 1/4 inch shank diameter, making it a compact, direct-mount option for high-speed finishing passes. Right-hand cutting direction suits standard spindle rotation without adapters.

This chamfer mill is suited for production machining and tool-and-die work where consistent edge geometry is required. The single-end configuration and solid carbide construction make it appropriate for use in vertical machining centers, CNC mills, and manual knee mills. Typical applications include chamfering drilled hole entries, deburring part edges prior to assembly, and producing defined angular profiles on steel, aluminum, and similar machinable materials. Machinists and toolroom technicians in job shops, OEM manufacturing, and maintenance environments will find this a standard-fit tool for everyday chamfering work.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating improves heat resistance and extends tool life in dry or high-speed cutting
• 1/4 inch cutter head and 1/4 inch shank for direct collet or end mill holder mounting
• 2-flute design balances chip clearance and edge strength for chamfering operations
• Right-hand cutting direction compatible with standard CNC and manual spindle rotation
• Single-end configuration with 0.229 inch length of cut for precise edge control

Compatibility

Designed for use with standard 1/4 inch collets, end mill holders, and shrink-fit toolholders in CNC machining centers and manual mills performing chamfering and deburring operations.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the 1/4 inch shank in a clean, properly torqued collet or end mill holder before spindle engagement. Inspect the tool edge and coating for chips or wear before each use. Do not exceed the recommended spindle speeds and feed rates for the workpiece material and tool diameter.
