Harvey Tool 830645-C3 Chamfer Mill 0.04in 2 Flute Altin

Product Description

The HARVEY TOOL 830645-C3 is a solid carbide chamfer mill designed for precision chamfering, deburring, and edge-breaking operations on metalwork. With a 0.04-inch cutter head diameter and a 0.02-inch length of cut, this is a fine-geometry tool suited for small-feature work where control and repeatability matter. The AlTiN coating improves heat resistance and tool life in ferrous and hardened materials. Two right-hand flutes provide a clean, efficient cut. Machinists and tool-and-die professionals reach for this style of end mill when working tight tolerances on small components or detailed chamfer profiles.

This chamfer mill is well suited for CNC machining centers and manual mills handling small precision parts. The 1/8-inch shank diameter makes it compatible with standard collets and tool holders found in most machine shops. The 2.5-inch overall length provides adequate reach without sacrificing rigidity at this diameter. Typical applications include chamfering drilled hole entries, deburring edges on machined components, and producing consistent angular profiles on ferrous alloys, stainless steel, and similar materials where AlTiN coating delivers an advantage.

Key Features

• 0.04-inch cutter head diameter for fine, small-feature chamfering
• AlTiN coating for elevated heat resistance and extended tool life in hard and ferrous materials
• Solid carbide construction for rigidity and wear resistance
• 2 right-hand flutes for clean chip evacuation and efficient cutting
• 1/8-inch shank diameter fits standard collets and tool holders
• 2.5-inch overall length balances reach with stability

Compatibility

Designed as an OEM-style replacement and standard production chamfer mill compatible with CNC machining centers and manual mills accepting a 1/8-inch collet or tool holder.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully powered down and locked out. Ensure the collet and tool holder are clean and free of debris before seating the shank to the full collet depth. At this diameter, avoid excessive runout in the tool holder, as even small amounts of runout will significantly reduce tool life and chamfer quality. Follow the tool manufacturer and machine OEM guidelines for speeds and feeds appropriate to the workpiece material and coating type.
