Accupro EM99943872 Chamfer Mill 1/2 in 4 Flute Carbide

Product Description

The ACCUPRO EM99943872 is a solid carbide chamfer mill designed for precision chamfering, deburring, and edge-breaking operations on metal workpieces. With a 0.5 inch cutter head diameter, 4 flutes, and a right-hand cutting direction, this tool delivers clean, consistent chamfer profiles in a single pass. The AlTiN coating provides high heat resistance and improved tool life in demanding cutting environments. The single-end configuration keeps the tool compact while maintaining rigidity during operation. Machinists and toolroom technicians working with ferrous and non-ferrous metals will find this tool suited to both production and prototype work.

This chamfer mill is appropriate for use in vertical machining centers and milling machines where chamfering, countersinking, or edge preparation is required. The 0.5 inch shank diameter is compatible with standard ER and end mill holders. With a 3 inch overall length and a 0.21 inch length of cut, the EM99943872 is best suited for shallow chamfer depths on flat or near-flat surfaces. It is a solid option for shops running steel, stainless, aluminum, and similar materials where a coated carbide tool provides a performance and longevity advantage over uncoated alternatives.

Key Features

• Solid carbide construction for rigidity and wear resistance in high-speed cutting
• AlTiN coating improves heat resistance and extends tool life in ferrous applications
• 4-flute geometry provides smoother surface finish and faster feed rates compared to 2-flute designs
• Right-hand cutting direction compatible with standard CNC and manual milling setups
• Single-end configuration with 0.5 inch shank fits common end mill holders and collet chucks
• 3 inch overall length provides clearance for most standard workholding setups

Compatibility

Designed as an OEM-style replacement and standard tooling option for milling machines and machining centers that accept 1/2 inch shank end mill holders or collet-style toolholders.

Installation Notes

Installation and tool changes must be performed with the machine spindle fully stopped and locked out per applicable safety procedures. Ensure the shank is fully seated and properly torqued in the toolholder before operation. Inspect the collet or end mill holder for wear before mounting this tool. Verify spindle speed and feed rate settings against material specifications before cutting.
