Harvey Tool 57878-C6 Square End Mill 5/64 in 7 Flute Altin

Product Description

The HARVEY TOOL 57878-C6 is a solid carbide square end mill designed for high-performance milling in demanding machining environments. With a 5/64 inch (0.0780 inch) cutting diameter and 7 flutes, this end mill delivers smooth surface finishes and efficient chip evacuation in tight-tolerance applications. The AlTiN coating provides heat resistance and wear protection, making it well suited for hard metals and abrasive materials at elevated cutting speeds. A variable helix design reduces harmonic vibration and chatter during the cut. This tool is installed and run by machinists and CNC operators in production and job-shop settings.

This end mill is intended for use in CNC machining centers and manual mills where small-diameter, multi-flute tooling is required. The 5/64 inch diameter and 15/64 inch length of cut make it appropriate for slotting, profiling, and contouring in confined areas or on small features. The 1/8 inch shank diameter fits standard collets and tool holders common in both vertical and horizontal milling setups. Right-hand cutting and right-hand flute direction are standard for conventional and climb milling operations.

Key Features

• Solid carbide construction for rigidity and extended tool life
• AlTiN coating improves heat resistance and wear performance in hard and abrasive materials
• 7-flute geometry increases feed rates and improves finish quality at small diameters
• Variable helix angle reduces chatter and vibration during cutting
• Right-hand cut and right-hand flute direction for standard milling operations
• 1/8 inch shank diameter fits widely available collets and tool holders

Compatibility

Designed as a replacement-style solid carbide square end mill for CNC and manual milling machines accepting a 1/8 inch shank diameter collet or tool holder.

Installation Notes

This tool is installed by machinists and CNC operators. Ensure the spindle is fully powered down and at rest before changing tooling. Seat the shank fully and evenly in a clean, undamaged collet to the recommended engagement depth per the tool holder manufacturer. Do not exceed the tool's rated length-of-cut range of 0.2000 to 0.3000 inches when programming axial depth of cut.
