Accupro EM99943864 Chamfer Mill 1/2 in 4 Flute Carbide Altin

Product Description

The ACCUPRO EM99943864 is a solid carbide chamfer mill designed for deburring, chamfering, and edge-breaking operations on a wide range of workpiece materials. The cutter features a 0.5-inch head diameter, four flutes, and a single-end configuration with right-hand cutting direction. An AlTiN coating improves heat resistance and extends tool life in ferrous and hardened materials. The 0.784-inch length of cut provides adequate engagement depth for standard chamfering work. This tool is installed and used by machinists, toolroom technicians, and CNC mill operators in production and job-shop environments.

This chamfer mill is suited for use on vertical machining centers, CNC mills, and manual milling machines where precise edge preparation is required. Its 0.5-inch shank diameter fits standard ER collet chucks and end mill holders commonly found in shop environments. The 3-inch overall length allows clearance in most standard setups without excessive tool overhang. It is appropriate for chamfering operations on steel, stainless steel, cast iron, and other ferrous materials where an AlTiN coating provides the best performance advantage.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• AlTiN coating improves oxidation resistance and supports dry or minimal-coolant cutting
• Four-flute design increases feed rate capability compared to two-flute alternatives
• Right-hand cutting direction compatible with standard spindle rotation on most machining centers
• Single-end configuration with 0.784-inch length of cut for consistent chamfer depth
• No coolant-through requirement simplifies toolholder selection

Compatibility

Designed as a direct-fit replacement for 0.5-inch shank chamfer mills used in standard ER collet chucks and end mill holders on CNC and manual milling machines.

Installation Notes

Installation is performed by a machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool is seated to the correct gauge length in the holder before tightening. Use a calibrated torque wrench on collet nuts per the toolholder manufacturer's specification. Verify runout with a dial indicator before beginning production cuts to avoid premature edge chipping on this solid carbide tool.
