Accupro EM99943851 Chamfer Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO EM99943851 is a solid carbide chamfer mill designed for precise chamfering, deburring, and edge-breaking operations on a range of workpiece materials. The cutter features a 3/16 inch (0.1875 inch) head diameter, a 4 inch overall length, and a matching 3/16 inch shank diameter. With 2 flutes and a right-hand cutting direction, it delivers clean, consistent chamfer profiles. The AlTiN coating improves heat resistance and wear life, making this mill well suited for harder ferrous materials and high-speed dry cutting conditions. Machinists and CNC operators working in job shops, production facilities, or tool rooms will find this cutter appropriate for light-duty chamfering on steel, stainless, and cast iron.

This chamfer mill is used in machining centers, knee mills, and CNC milling applications where controlled chamfer geometry is required. It handles edge preparation on drilled holes, milled pockets, and part perimeters. The single end type concentrates cutting geometry at one end for straightforward tool holding in standard collets or end mill holders. Its compact 3/16 inch diameter suits close-tolerance work and smaller features where larger chamfer mills cannot reach.

Key Features

• Solid carbide construction for rigidity and extended tool life compared to HSS alternatives
• AlTiN coating for improved thermal resistance and reduced wear in ferrous and high-alloy applications
• 2 flutes with right-hand cutting direction for smooth chip evacuation during chamfering
• 3/16 inch cutter head diameter with 0.1880 inch length of cut for precise edge geometry
• 4 inch overall length provides reach in standard tool holders without excessive overhang
• Single end design for straightforward mounting in collet chucks and end mill holders

Compatibility

Designed as a direct-fit replacement chamfer mill for CNC machining centers and manual mills accepting a 3/16 inch shank diameter in standard collet or end mill holder systems.

Installation Notes

A licensed machinist or CNC operator should install this tool using a properly sized collet or end mill holder rated for the 3/16 inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Do not exceed the tool holder manufacturer recommended runout tolerances, as carbide tools are sensitive to improper seating. Verify feed and speed parameters against the workpiece material before initiating a cut.
