Accupro EM99943842 Chamfer Mill 3/16 in 2 Flute Carbide

Product Description

The ACCUPRO EM99943842 is a single-end chamfer mill designed for chamfering, deburring, and edge-breaking operations on metallic workpieces. Built from solid carbide, it provides the rigidity and wear resistance required for consistent cuts in steel, stainless, aluminum, and similar materials. The cutting geometry features two right-hand flutes with a 3/16 inch cutter head diameter, producing clean, repeatable chamfer profiles. An AlTiN coating extends tool life by reducing heat buildup at the cutting edge, particularly during dry or semi-dry machining. This tool is sized for precision work in tight setups and is commonly used by machinists in production and job-shop environments.

The EM99943842 is suited for use on CNC machining centers and manual mills where edge preparation is required prior to assembly, inspection, or welding. Its 3/16 inch shank diameter is compatible with standard collet chucks and tool holders found on most light-duty to mid-range CNC platforms. The 2 inch overall length provides clearance for most standard workholding setups without excessive overhang. This chamfer mill is a single-use replacement-grade tool packaged individually.

Key Features

• Solid carbide construction for high rigidity and wear resistance
• AlTiN coating reduces thermal load and extends cutting life
• Two right-hand flutes for efficient chip evacuation
• 3/16 inch cutter head diameter for precision edge work
• 0.784 inch length of cut for controlled chamfer depth
• No coolant-through design - suitable for dry or flood coolant from exterior

Compatibility

Designed as a direct replacement chamfer mill for use in standard 3/16 inch collet chucks and compatible tool holders on CNC machining centers and manual milling machines requiring a single-end chamfer geometry.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Inspect the collet and holder for debris or wear before seating the shank. Verify tool projection and runout with a dial indicator before initiating a cut.
