Harvey Tool 888447-C4 Square End Mill 3/64 in 3 Flute Carbide

Product Description

The HARVEY TOOL 888447-C4 is a solid carbide square end mill engineered for precision milling in demanding machining environments. With a 3/64 inch (0.0469 inch) cutting diameter and a 3/16 inch length of cut, this tool is built for tight-tolerance work in small-feature applications. The three-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth cutting action. An amorphous diamond coating extends tool life and reduces friction, making this end mill well-suited for cutting abrasive or composite materials. Licensed machinists and CNC programmers working with fine-feature parts will find this tool appropriate for their applications.

This end mill is designed for single-end use with right-hand cutting and right-hand flute direction. The 1/8 inch shank diameter fits standard collets used on CNC machining centers and high-speed spindles. The 2-1/2 inch overall length provides adequate reach for most small-feature milling operations without sacrificing rigidity. It is center-cutting, allowing plunge entry into the workpiece. Typical applications include slot milling, profiling, and contour work on small, precision components in aerospace, medical device, and general manufacturing environments.

Key Features

• 3/64 inch cutting diameter for fine-feature and small-slot milling
• Three-flute design balances chip evacuation and cutting edge strength
• 30-degree helix angle promotes smooth, stable cutting action
• Amorphous diamond coating for extended tool life in abrasive materials
• Center-cutting geometry allows direct plunge entry
• Solid carbide construction for rigidity and wear resistance

Compatibility

Designed for use with 1/8 inch collets on CNC machining centers and high-speed milling spindles. Suitable for right-hand spindle rotation. Compatible with standard ER and precision collet systems accepting a 1/8 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully powered down and at a complete stop before inserting or removing the end mill from the collet. Confirm collet size matches the 1/8 inch shank before tightening to avoid runout or tool pull-out. Follow machine manufacturer guidelines and applicable shop safety procedures for tool holding and speeds and feeds setup.
