Harvey Tool 804816-C3 Corner Chamfer End Mill 0.25in 4F

Product Description

The HARVEY TOOL 804816-C3 is a solid carbide corner chamfer end mill designed to machine precise chamfered edges while simultaneously performing standard milling operations. Built for demanding metal-removal applications, it features a 0.25-inch mill diameter, a 0.75-inch length of cut, and a 0.02-inch chamfer width at a 45-degree chamfer angle. The AlTiN PVD coating provides thermal resistance and wear protection, extending tool life in ferrous and high-strength materials. With 4 helical flutes at a 30-degree helix angle and a center-cutting design, this end mill handles both roughing and finishing passes in a single tool. Machinists and CNC operators in job shops and production environments rely on this geometry for edge-break and chamfering work without a tool change.

This end mill is suited for use on steel, stainless steel, cast iron, and non-ferrous metals. It fits applications requiring tight chamfer tolerances on small-diameter features, particularly in aerospace, medical, and precision machining contexts. The 1/8-inch straight-cylindrical shank allows it to run in standard collet chucks and end mill holders on CNC machining centers and manual mills. The regular length type and single-end construction make it a direct-reach tool for most standard setups without extension.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN PVD coating for elevated-temperature performance and extended tool life
• 45-degree chamfer angle with 0.02-inch chamfer width for consistent edge breaks
• Center-cutting design allows plunge entry and versatile toolpath options
• Right-hand cut, right-hand flute direction with 30-degree helix for efficient chip evacuation
• Compatible with steel, stainless steel, cast iron, and non-ferrous metals

Compatibility

Rated for primary workpiece materials including steel, stainless steel, cast iron, and non-ferrous metals. Fits standard 1/8-inch bore collet chucks and end mill holders. Part of the Harvey Tool Miniature End Mills series.

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the control is in an E-stop or safe state before loading or unloading the tool. Verify collet bore matches the 0.125-inch shank diameter and that tool runout is within acceptable limits before cutting. Follow the tool manufacturer feed-and-speed recommendations for the specific workpiece material and do not exceed the tool's rated length of cut.
