Harvey Tool 63047-C6 Corner Radius End Mill 0.047 in 3 Flute

Product Description

The HARVEY TOOL 63047-C6 is a solid carbide corner radius end mill engineered for high-performance material removal in demanding machining applications. Measuring 0.047 inches in diameter with a 0.005-inch corner radius, this single-end tool carries a 3-flute, variable-helix geometry that reduces harmonic chatter and improves chip evacuation. An AlTiN (aluminum titanium nitride) PVD coating delivers elevated heat resistance, making it well suited for prolonged cuts in abrasive, high-temperature workpiece materials. The extended-reach, stub-flute design provides rigidity in tight-clearance operations while maintaining access to deep features. Licensed machinists and CNC operators working with difficult-to-machine alloys will find this tool optimized for both roughing and finishing passes in a single setup.

This end mill is designed for use in steel, stainless steel, cast iron, and hard alloys. The extended-reach configuration targets applications where standard-length tools cannot access recessed pockets, slots, or contoured features without interference. The stub flute length of approximately 1.125 inches (converted from stated LOC data) keeps deflection low despite the extended 0.570-inch reach, making it a practical choice for precision mold, die, and aerospace component work where dimensional accuracy is critical. A high-precision toolholder is recommended for best results with this diameter class.

Key Features

• Variable-helix geometry reduces resonance and chatter at elevated spindle speeds
• AlTiN PVD coating enhances heat resistance and tool life in hard and high-temp alloys
• Extended-reach, stub-flute design balances rigidity with deep-feature access
• Center-cutting capability allows plunge entry without a pre-drilled pilot hole
• Right-hand cut and right-hand flute direction for standard CNC mill setups
• Corner radius tolerance held to plus or minus 0.0010 inches for consistent edge blending

Compatibility

Designed for use in the HARVEY TOOL Variable Helix End Mills for High Temp Alloys series. Intended for use with a high-precision toolholder. Primary workpiece materials include steel, stainless steel, cast iron, and hard alloys (material codes P, M, K, H).

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom professional. Secure the 0.125-inch straight cylindrical shank in a high-precision collet or hydraulic toolholder, verifying runout before cutting. Power down and lock out the spindle before changing or inspecting tooling. At this diameter, avoid side-loading the tool beyond programmed parameters, as micro-diameter carbide end mills are susceptible to breakage from unexpected fixture contact or workpiece movement.
