Accupro EM99943835 Chamfer Mill 1/4 in 3 Flute Solid Carbide

Product Description

The ACCUPRO EM99943835 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on ferrous and non-ferrous materials. The cutter head measures 0.250 inches in diameter with a 0.355-inch length of cut. Three right-hand flutes provide efficient chip evacuation and a clean, consistent chamfer profile. An AlTiN (aluminum titanium nitride) coating improves heat resistance and extends tool life in demanding cutting conditions. This tool is built for machinists and tool-and-die professionals working in job shops, production environments, and maintenance machining operations.

This chamfer mill is suited for general-purpose chamfering and deburring on CNC machining centers and manual mills. The 1/4-inch shank diameter fits standard collets and end mill holders commonly found in both vertical and horizontal milling setups. The 2.5-inch overall length provides adequate reach for most workholding configurations without sacrificing rigidity. Single-end construction means the tool is replaced rather than reground when the cutting edge is spent.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed applications
• AlTiN coating for improved thermal resistance and extended tool life
• 3-flute geometry with right-hand cutting direction for efficient chip removal
• 0.355-inch length of cut suitable for standard chamfering depths
• Single-end design with 1/4-inch shank for compatibility with standard collet systems
• No coolant-through requirement simplifies setup

Compatibility

Designed for use in standard 1/4-inch collets and end mill holders on CNC machining centers and manual milling machines. Confirm holder runout tolerance before use to protect the cutting edge.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a locked-out, de-energized state per applicable machine safety procedures. Seat the shank fully into the collet or holder and torque the drawbar or collet nut to the toolholder manufacturer's specification. Inspect the cutting edges for chips or damage before each use. Solid carbide tools are brittle - avoid side loads or interrupted cuts beyond the tool's rated capacity.
