Accupro EM99943862 Chamfer Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO EM99943862 is a single-end chamfer mill designed for chamfering, deburring, and edge-breaking operations on a range of workpiece materials. Built from solid carbide with an AlTiN (aluminum titanium nitride) coating, this tool delivers heat resistance and extended wear life in demanding cutting conditions. The cutter head measures 0.375 inches in diameter with a matching 3/8-inch shank, and the overall tool length is 2.5 inches. Three flutes and a right-hand cutting direction make it suitable for general-purpose chamfering on CNC machining centers and manual mills where consistent edge quality is required.

This chamfer mill is used in metalworking environments where precise chamfer angles and clean edge preparation are critical. The AlTiN coating makes it well suited for dry or near-dry machining of hardened steels, stainless, and high-temperature alloys. Its compact 2.5-inch overall length fits standard toolholders without extended reach. Machinists, toolroom technicians, and CNC operators working in production or job-shop settings will find this tool appropriate for both roughing chamfers and finish edge work.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN coating provides high-temperature resistance and reduced tool wear in dry cutting
• 3-flute geometry balances chip evacuation and finish quality
• Right-hand cutting direction compatible with standard CNC spindle rotation
• 0.375-inch shank fits common collet and toolholder systems
• Single-end design for straightforward setup and tool-length offsets

Compatibility

Designed as an OEM-style replacement chamfer mill for use in standard 3/8-inch collets and toolholders on CNC machining centers and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Ensure the spindle is fully stopped and machine is powered down or in an e-stop state before changing tooling. Seat the shank fully in the collet or toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify tool-length offset in the control before initiating a cutting cycle.
