Accupro EM99943844 Chamfer Mill 3/8 in 2 Flute Carbide

Product Description

The ACCUPRO EM99943844 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on ferrous and non-ferrous materials. The cutter features a 3/8 inch head diameter, 2 flutes, and a right-hand cutting direction. An AlTiN coating increases surface hardness and heat resistance, extending tool life in dry or semi-dry cutting environments. The 2.5 inch overall length and 3/8 inch shank diameter make it compatible with standard end mill holders and collet chucks found in CNC machining centers and manual mills. Machinists and tool and die professionals select this geometry for consistent chamfer angles and clean edge finishes on production and prototype work.

This chamfer mill is suited for use in job shops, production machining, and maintenance environments where precise edge preparation is required. It performs on a wide range of materials including steel, stainless steel, cast iron, and aluminum alloys. The single-end design and compact overall length make it practical for close-tolerance setups where tool clearance is limited. It is typically installed in CNC vertical machining centers, knee mills, and drill press setups with appropriate collet toolholding.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-material applications
• AlTiN coating provides elevated heat resistance and extended tool life in dry cutting
• 3/8 inch cutter head diameter with 0.364 inch length of cut for controlled chamfer depth
• 2-flute geometry balances chip clearance with edge strength
• Right-hand cutting direction compatible with standard CNC and manual spindle rotation
• 3/8 inch shank diameter fits common collet and end mill holder systems

Compatibility

Designed as a standard-shank chamfer mill compatible with 3/8 inch collets and end mill holders used in CNC machining centers and conventional milling machines.

Installation Notes

Installation should be performed by a qualified machinist or toolroom professional. Power down and lock out the spindle before inserting or removing the tool from the holder. Ensure the shank is fully seated and the collet nut or set screw is torqued according to the toolholder manufacturer specifications. Verify spindle rotation direction matches the right-hand cutting geometry before engaging the workpiece.
