Accupro EM99943861 Chamfer Mill 3/8 in 3 Flute Carbide

Product Description

The ACCUPRO EM99943861 is a single-end chamfer mill designed for producing chamfers, bevels, and angled edges on a variety of workpiece materials. The cutter head measures 0.375 inches in diameter with a 3/8 inch shank diameter and an overall length of 2.5 inches. Constructed from solid carbide and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures and abrasive materials well. The three-flute geometry provides a balance of chip evacuation and surface finish. Right-hand cutting direction suits standard CNC and manual milling setups. Machining professionals and toolroom operators use this end mill for edge preparation and deburring operations.

This chamfer mill fits residential and industrial machining environments where precise edge preparation is required. It is suited for use on hardened steels, stainless steel, cast iron, and high-temperature alloys where the AlTiN coating provides thermal and wear resistance. The 0.588 inch length of cut allows clean chamfer passes at consistent depth. It is appropriate for use in vertical machining centers, CNC mills, and manual milling machines with standard R8 or collet toolholding that accepts a 3/8 inch shank.

Key Features

• Solid carbide construction for rigidity and extended tool life in abrasive materials
• AlTiN coating improves heat resistance and wear performance at elevated cutting speeds
• 3-flute design balances chip clearance and finish quality
• 0.588 inch length of cut for consistent chamfer depth
• Right-hand cutting direction compatible with standard spindle rotation
• Single-end configuration with 3/8 inch shank for broad toolholder compatibility

Compatibility

Designed as an OEM-style replacement chamfer mill for use in standard 3/8 inch collet or toolholder systems on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool path program is cleared before changing tooling. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the drawbar or collet nut per the toolholder manufacturer specification. Verify runout with a dial indicator before commencing a production cut.
