Harvey Tool 875447-C6 Square End Mill 3/64 in 4 Flute Altin

Product Description

The HARVEY TOOL 875447-C6 is a solid carbide square end mill designed for precision milling in demanding metalworking applications. With a 3/64 inch (0.0470 inch) mill diameter and a 9/64 inch (0.141 inch) length of cut, this tool is built for tight-tolerance work in small-feature machining. The 4-flute, right-hand cutting geometry paired with a 34-degree variable helix promotes chip evacuation and reduces chatter, resulting in improved surface finishes on ferrous and non-ferrous materials. The AlTiN coating adds thermal resistance and extends tool life under high-speed cutting conditions. This end mill is a single-end tool and is not center-cutting.

This end mill is suited for CNC milling operations requiring fine detail work, including slotting, profiling, and finishing passes on hard metals and alloys. The 1/8 inch shank diameter fits standard collets and end mill holders commonly found in vertical machining centers and high-speed spindle setups. The 1-1/2 inch overall length keeps the tool rigid during high-feed passes. It is typically installed and operated by machinists and tool-and-die professionals working on precision components in aerospace, medical device, and mold-making environments.

Key Features

• 3/64 inch mill diameter with 0.0470 inch decimal equivalent for precise small-feature machining
• 4-flute, right-hand cutting and flute direction for improved chip flow and finish quality
• 34-degree variable helix reduces vibration and chatter during high-speed passes
• AlTiN coating provides thermal resistance and extends tool life in ferrous materials
• Solid carbide construction delivers rigidity and wear resistance in hard-material applications
• 1/8 inch shank diameter compatible with standard collets and end mill holders

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide end mill for CNC vertical machining centers and high-speed spindle setups accepting a 1/8 inch shank diameter.

Installation Notes

This end mill is installed by qualified machinists following standard tooling change procedures. Power down and lock out the spindle before seating or removing the tool from the collet or end mill holder. Ensure the shank is clean and fully seated to the correct insertion depth before torquing the collet nut. Follow the machine manufacturer and tooling manufacturer guidelines for speed, feed, and depth-of-cut parameters appropriate for the workpiece material.
